The world. Plant development from seed

At the dawn of human history, the spring awakening of life in a germinating seed should have attracted the attention of our distant ancestor, and, undoubtedly, was perceived by him as a miracle.

From casual observations of seed germination primitive passed on to their conscious sowing, which for many centuries was performed as a religious rite. Thus, for example, religious legends and myths associated with the sowing and germination of seeds served the priests of a slave-owning society as a means of forcing the population to work in the fields, where this work was carried out under the guise of serving a deity.

I was interested in the topic of the development of plants from seeds. I was interested to know whether a plant from a seed will germinate in the same way or not under any conditions, how the absence of light or water affects the growth of a plant, how development occurs if the plant is exposed to harmful radiation. I decided to conduct a study and identify the most suitable conditions for the growth and development of a plant at home. For the experiment, I took bean seeds.

Relevance of the topic: Growing flowers and other plants in their apartments, a person not only decorates his home. Plants are a source of oxygen useful substances, energy, have the properties of medicine. As a result of the activity of plants, the air in cities is cleaned of gases, dust, and soot. Plant development is becoming increasingly dependent on environmental factors that change soil properties, plant growth and quality. Modern man cannot imagine his life without electromagnetic devices. Therefore, the identification of the most favorable conditions for plant growth today is relevant and useful.

The purpose of the study: experimentally compare various conditions for the development of a plant from a seed, depending on environmental factors (light, heat, humidity, radiation) and to identify the most favorable ones.

Having studied the literature on this topic, I found out that each seed resembles a small bag in which the future plant is packed. The seed contains not only the new plant, but also all the substances necessary for its nutrition.

The tiny sprout that is in the seed is called the germ, or embryo. A stem and leaves grow from its upper part. A process departs from the rest of the embryo, from which a root then develops. Seeds grow at favorable conditions. For seed germination various kinds plants require different conditions, but some conditions are necessary for all seeds without exception. These conditions are warmth, sufficient moisture, oxygen and sunlight. Under these conditions, the stock nutrients begins to nourish the embryo. The embryo grows, the root and shoot systems are formed - having broken the seed peel, they go outside. Now they can be planted in the soil and, very importantly, placed at the same time less often so that young plants can grow freely. Appears soon young plant, which gradually becomes similar to the parent plant.

Beans are a widespread plant in the legume family. The stem is strongly branched, covered with short hairs, has the ability to curl, but in the absence of support, the plant spreads along the soil, the leaves are alternate, have a long petiole, and are equipped with small stipules; moth-type flowers, collected in a rare axillary raceme, are white, pinkish or purple. The fruit is a bean, cylindrically straight or somewhat curved, the color of bean beans can be very different: from white and pink to brown and dark purple.

II STAGE. Survey of gardeners.

The second stage was aimed at exploring the various opinions of amateur gardeners about the conditions in which seedlings should be kept in order to successfully grow and mature.

My grandmothers are amateur gardeners. Each time in the spring they begin to plant different seeds, wait until the plant is ready for planting in the garden. Each grandmother has her own place in the apartment, where, in her opinion Better conditions for the development of plants and its method of planting, loosening and watering. One grandmother has this place - a window sill on the sunny side with rare watering. The second grandmother places pots with sprouts on the floor near the radiator, where the light is less bright and she waters the sprouts more often.

So what are the best conditions? It is impossible to understand this between two people, you need to take a third gardener, who will be my grandmother's neighbor in the garden, aunt Natasha.

Aunt Natasha has her own excellent view on growing seedlings. She puts the seedlings in places that depend on the day from the moment of planting. The first 5 days - the seedlings stand in a dark, warm place and frequent watering. The following days, the seedlings stand in a bright, cool place with more rare watering.

Thus, the opinion of Aunt Natasha united the opinion of the two grandmothers. This can only mean one thing - that there is no consensus on the method and place of growing plants. Suitable conditions can only be determined experimentally.

V STAGE. Final.

The experiments carried out prove that it is really necessary for the development of a plant to create favorable conditions for it.

1. All the bean sprouts appeared at the same time - so I properly soaked the seeds in a well-moistened gauze. Seeds need not only water, but also oxygen; if the seeds are drowned in water, then it prevents the embryos from breathing, and the embryos can “suffocate”.

2. Shoots appear fastest in the dark. Therefore, until the first shoots appear, it is better to keep pots with germinated seeds in a dark place.

3. Plant for full development light, moisture and heat are needed. The plant in pot #4, which grew in a dark, warm place and had limited water, was the first to die. Despite the fact that at first it grew and developed even better than plants in pot No. 1. The plant died two weeks after emergence.

4. During the whole month, plants developed in a pot No. 3. But pale color, lack of leaves, lethargy, not healthy appearance indicate that light is a necessary condition for the good development of plants.

5. The life of plants in pot No. 2, standing in a bright place in the field of electromagnetic radiation, shows that radiation has a detrimental effect on plants. Bean sprouts came first, plants were different rapid growth, but soon the growth and development ceased. It turns out that radiation is more dangerous for plants than the absence of light.

6. For the full growth and development of plants, oxygen, light, heat, moisture, and the absence of harmful radiation are necessary.

Goals:

1. Determine the conditions for the germination and development of a plant from a seed as a result of practical work.
2. Teach students various methods solve a problem or gain new knowledge (experiments, information retrieval, computer, encyclopedia, etc. sources) and practically apply the acquired knowledge and experience in life.

Teacher questions:

– Why is there life on Earth? (formed special conditions: water, soil, air.)

– What would happen on the Earth if it flew around the Sun in a different orbit? (The celestial bodies more distant from the Sun receive too little solar heat, they are very cool, and those closer to the Sun are too hot for living beings.)

- What is the main condition for the emergence and development of life on Earth? (The Earth has air and water shells. Air and water have become the main conditions for the emergence and development of life on Earth.)

What does every living thing on Earth need? (In heat, light, water and air.)

What is the name of the science that studies wildlife? (Biology - "BIOS" - life, "LOGOS" - teaching.)

- How did the science of plants - botany - appear? (Ancient people, collecting plants, accumulated knowledge about them.)

III. Formulation of the problem

SPRING is the sun
SPRING is joy
Spring is life.
The evil blizzard has vanished,
The night became shorter than the day.
A warm wind blows from the south
Drops fall, ringing ...
The blizzards subsided in the fields
in their white beds.
And SPRING is coming everywhere
Drives winter from the yard.

HOW SEEDS GROW

Each seed has a tiny plant embryo inside its tough outer shell. In order for it to grow, each seed contains a supply of nutrients. The most important thing that is necessary for the germination of the embryo is water and heat. Therefore, the young shoot is always directed towards the sunlight. And the root grows down into the soil.

Seed growth begins like this: water penetrates the seed coat, and it swells. The root breaks through the shell first and begins to grow down. Then a sprout breaks up. The root is overgrown with thin, hair-like processes that pull water and minerals from the soil. After the sprout breaks to the surface of the soil, green leaves appear on it.

Relevance

The world of plants is amazing and diverse. Every attentive observer and thoughtful researcher can discover something new in it. At the lessons of the "World around" we got acquainted with plant growing, with the development of plants from seeds. This was the basis for the creation of our project. In our class, several students expressed a desire to grow their own plant and observe its development.

Hypothesis

Among the wide variety of plants, there are those that are not so demanding on the length of daylight hours and can grow in artificial conditions. Therefore, we suggested that both mandarin and tomato seeds can be germinated at home.

Project Implementation Plan

1. Specify the conditions for the growth of mandarin, tomato.
2. Germinate the seeds and place them in the soil.
3. Watch the development of sprouts.
4. Monitor compliance with the conditions.
5. Keep an observation diary.
6. Get the end result.
7. Make a conclusion.

Expected results

It is assumed that as a result of the work a project will be created.

Grade 4 students will show interest and take an active part in finding materials about plants in order to further design the project.

The implementation of the project will solve the problems of educating an active life position children, the formation of a sense of responsibility.

Project implementation

"Development of a plant from a seed"

The project, which was implemented from December 23, 2011 to February 21, 2012, can be described as research. The project involved 3 students of the 4th grade.

Stages of project implementation:

1. introduction to the project (December 23, 2011)
2. individual work in the project (December 23, 2011 - February 10, 2012)
3. registration and presentation of observations in the form of observation diaries (February 16, 2012)
4. creation of a collective project (February 21, 2012)

At the first stage the topic of the project was chosen, after discussing the situation, a hypothesis was identified, project participants were selected.

At the second stage carried out independent work project participants according to their individual tasks. To search for the necessary information, Internet resources and the library fund were used.

At the third stage the results of their observations are presented in the form of observation diaries. The project participants shared their observations with the class.

On the final stagethe focus was on the collective analysis of past cases and the creation of a project.

Project results

Our research has proven that plants such as mandarin or tomato are not as demanding on the length of daylight hours and can grow in artificial conditions.

Life flowering plant starts from the seed. Seeds may vary in shape, size, weight and color, but the principles of structure of all seeds are the same. Nutrients are necessary for the development of any plant.

Instruction

A seed consists of an embryo, a peel and a supply of nutrients. The germ of the future plant is the embryo. It distinguishes germinal root, stalk, kidney and cotyledons. The supply of nutrients necessary for the development of the embryo is located in the endosperm - a special storage tissue inside the seed.

Plants can be dicot or monocot. The embryos of the first have two cotyledons, the second - one. The volume ratio of the embryo and endosperm can also vary: in some plants (ash, wheat, onion), the embryo is small, and the entire volume of the seed is occupied by storage tissue, while in others, on the contrary, as it matures and grows, the embryo displaces the endosperm (in apple and almond ). In a number of plants (beans, pumpkins, arrowheads, chastukhas), the seed can consist only of the embryo and seed coat, and their supply of nutrients is concentrated in the cotyledons and other cells of the embryo.

So, the seed is the germ of the future plant and the "reserve" of nutrients for its future growth. When it rests, the processes of vital activity in it proceed sluggishly and imperceptibly, but as soon as it gets into a favorable environment, these processes are activated. At this time, the seed germinates.

The beginning of a new plant is given only by seeds with a living embryo. For a number of reasons, the embryo may die. Diseases, pests, improper storage, etc. can make the seed unsimilar. Sometimes embryos can die from too long storage of seeds. When water gets inside the seed, all seeds swell, but only viable ones germinate, and those that do not germinate rot.

For seed germination, favorable conditions are needed, the main of which are the presence of water, air and heat. The embryo consumes nutrients exclusively in the form of a solution, however, different amounts of water are needed for different seeds. The same can be said about heat and air.

The root sprouts first from the seed of the plant: having broken the peel and coming out of the seed, it quickly grows and strengthens in the soil, absorbing water and minerals from it. Further, the stalk begins to grow, raising the kidney and cotyledons (future leaves) above the soil surface. In some plants, the cotyledons remain in the soil, and elevated escape develops from the kidney.

The organic matter stored in the seed is used to nourish the future plant until the seedling reaches the soil surface. But if they are used up before the process of photosynthesis begins, the seedling may die.

Goals:

1. Determine the conditions for germination and development of a plant from a seed as a result of practical work.
2. To teach students various methods to solve a problem or gain new knowledge (experiments, information retrieval, computer, encyclopedia, and other sources) and practically apply the knowledge and experience gained in life.
3. Develop educational and cognitive interest; cultivate curiosity, the need for new knowledge, inquisitive mind.
4. To cultivate love for one's land, a value attitude towards the life of people, plants, animals; to educate a successful student in oneself, to strengthen the concept of a “good student” model.
