Environmental factors acting on the body.
biotic
abiotic
both answers are correct
What influence has light on the plant?
growth, flowering, fruiting
germination of seeds
both answers are correct
Light is an ecological factor that determines the life of plants, most of which are photoautotrophones. Radiant sun energy - the background of the earthly life. sunlight Regulates the growth and development of plants, and can also have a damaging effect. Light is one of the most important factors in the life of a green plant, as it is a source of energy in the process of photosynthesis. It affects the other functions of the plant organism - on his growth, flowering, fruiting , as well as on germination of seeds. The attitude of plants to the light is different, three groups are distinguished by this sign: light-minded, teothelubiyi and shadowish.
The effect of living organisms on plants.
animals eat, pollinate
darken, used as a support
both answers are correct
Animals feed on plants, pollinate them, spread fruits and seeds. Large plants can shadow Young, small. Some plants use others as a support. Microorganisms decomposing Herbal residues enrich the soil with humus and minerals.
Effect of plants on the environment.
change the composition of the air, soil
fix and protect the soil from destruction
both answers are correct
Plants change the composition of the air: moisturize It is absorbed by carbon dioxide and excrete oxygen. Change the composition of the soil - absorb some substances from it and allocate others in it. Root systems of plants fix the slopes ravines, hills, river valleys, preventing soil from destruction. Forest planting protect fields from Sukhovyev.
Characteristic features of light-affiliated plants.
light affects the form of a plant
light affects the color of the plant: stem, leaf
both answers are correct
Light-loving plants live only on the opened places lit by the sun, where rather rare floral cover. Light has a lot influence on the form of plants. Growing outdoors are usually low, branched, with a wide crown. Light-loving plants have a characteristic structure of leaves. They are usually small, dense, with shiny thick skin and numerous stories. Many plant leaves are covered with wax rod or hairs, which protects them from direct exposure to sunlight. Well developed mechanical fabrics and root system.
Characteristic features of teothelubil plants.
weakly developed mechanical and conductive fabrics
sheet plates fragile and thin. Ust, on the top and bottom sides of the sheet
both answers are correct
Characteristic features of aquatic plants.
minor body surface
powerful root system
no correct answer
Most plants living in water have a very large body surface. They absorb water and dissolved in it with the entire surface of the body, and therefore the root system is poorly developed, and sometimes it is completely absent. Stitz on underwater leaves.
Types of plant communities.
forests, meadows, swamps
steppe, Tundra
both answers are correct
Vegetation is a combination of plant communities that exist in a certain territory. Depending on the prevalence of certain types and conditions of existence, plant communities are combined into large groups. Each type of vegetation has its own specific traitsFor which it can be distinguished from others. Meadows and Steppe - It overgrown herbs with a knee height, in a belt or higher human growth. Some meadow and steppe herbs pass the way from germination to fruiting and death in one season, others - for two, and the third lives throughout the years and decades. Swamps They call the community of plants, partially immersed in water and partially protruding from it. They are formed by cereals, seeds, mkami, shrubs. Plants tundra develop very slowly. Tundra plants, as a rule, low-minded - snow covers and flexs them. IN desertes Where the rains go every year, the communities of the ephemers develop. After the spring rains, the plant covers the soil of the carpet and for 3-8 weeks you have time to grow and bring fruits, and perennials - still stock nutrients. The size of the ephemers depends on moisturizes - plants that in rich moisture years reach the size of 30-39 cm, and in dry years it grows up to 3-4 cm. Some types of desert plants have small, almost imperceptible leaves or without them without them - photosynthesis carry out stalks . Other plants in the wet season leaves are large, and in dry - small.
Life forms of plants that make up a deciduous forest.
first tier: Oak, Lipa, Birch
first tier: herbs, cherry
first tier: Herbs and ferns
Communities of plants occur not by chance: they add up gradually for many millennia. As a result, different types of plants in the community adapt to joint habitat. Liality is most well expressed in forest communities. In the deciduous forest of oaks, linden, birch and other large trees form the first top tier.
Natural change of plant communities can be caused ...
changes in climate
composition or structure of soil; Life activity of the plants themselves
both answers are correct
Natural change of plant communities can be caused by changes in climate, composition or soil structure, the vital activity of the plants themselves. Influenced by these reasons in the community, some plants may appear, while others disappear. Forest communities also change vegetation. Under the birch forest can be perfectly growing with shadowish fir. Follow years. Spruce grows and occupies the top tier of the forest. Old birches are dying. And young light-loving birchs cannot survive - too little light for them under fir crowns. Gradually occurs the change of vegetation and in the lower tier. Thus, there is a change of birch forest by Elov.
