Where do grassy plants disappear for the winter? And how do they appear again after the chilly autumn and frosty winter? We will reveal this mystery of nature in our article.
Where grass plants disappear for the winter
Winter is not the best period for the development of plant organisms. Indeed, for normal life they need water in a liquid state, a certain air temperature and a sufficient amount of solar energy. How plants are preparing for winter can be considered on the example of grassy and perennial representatives of this kingdom of wildlife. So, irises, which are one of the most popular and unpretentious decorations of landscapes, have a thickened underground stem - rhizome. When the cold comes, the visible part of this plant dies. And in the thickened rhizome, water accumulates with the nutrients necessary in order to survive in an unfavorable period. With the onset of spring, leaves and flowers again grow from young buds.
Annual plants
What happens to plants in winter, which are annuals? Both the shoot and the root system die off. They do not grow in spring. For example, the well-known Chernobrivtsy will have to be sown again in March-April. Only in this case they will grow again. The thing is that grassy annuals do not have any adaptations to the cold. It is much easier in this regard to trees and shrubs. For the winter, they simply dump the foliage to reduce the intensity of the evaporation process. But gymnosperms, as they say, in the winter and summer in one color. In winter, the stomata of their leaves are clogged with resin, which automatically stops transpiration. Therefore, spruce and pine trees delight us all winter with their lush green cover.
Perennial plants
Where grassy plants that are annuals disappear for the winter, we figured out. They just cease to exist. But the two and perennial have a number of devices. Beets, carrots and radishes have root crops. In the first year, such plants do not produce seeds. They thicken the main root. It accumulates substances due to which plants will live in winter. But next summer, biennial plants will already give seeds that can be used to propagate them. Similarly, the process of experiencing adverse conditions occurs in primroses. They have underground modifications of shoots called bulbs. Tulips, crocuses and primroses bloom for only a few weeks in early spring. They spend the rest of the life cycle underground.
So, we figured out where the herbaceous plants disappear for the winter. Their annual representatives die off completely. Before this, they leave the seeds with which they are distributed. Biennial and perennial herbs undergo an unfavorable period underground. Due to the supply of nutrients and water, they carry out all the necessary processes of life. With the onset of heat, their growth and development resume. And again we can enjoy the bright colors of grassy plants.
