Some of the organic matter is not immediately consumed for vital processes, but is stored by the plant.
Organic matter can be deposited in the cells of fruits and seeds (in annual plants).
In biennial and perennial plants, the supply of nutrients can be deposited in the cells of roots, stems and their modifications.
Root crops of carrots, beets, rutabagas, turnips and some other plants are a kind of storehouse of nutrients.
Kohlrabi cabbage forms a thick, globular stem that looks like a turnip. In such a stem, the plant stores nutrients.
In trees and shrubs, the main reserves of organic matter are formed in the core and wood.
In the spring, these substances dissolve in water and rise through the vessels of plants to the blossoming buds. In spring, you can often see sap flowing from the wounds on the tree trunk. Often people cut the bark themselves to drink birch or maple sap.
With damage to the bark and a large loss of sap, trees weaken and may die. Therefore, plants should be protected from damage.
