Parts of Plants

Do you know what each part of plants do? This morning we studied the function of roots, leaves, stem and flowers.

Root
Roots originate from the lower portion of a plant and they are in the soil. Their functions are to absorb nutrients and moisture, anchor the plant in the soil, support the stem, and store food such as carrots. In some plants, they can be used for propagation.

Stem
The stem is the upper part of the plant and bears branches, leaves, flowers and fruits. Stem is generally green when young and later often become woody and dark brown. It conducts water and minerals from the root to the leaves. Some stems perform the function of storage of food for example potato, ginger and turmeric.

Leaves
Leaves provide trees with all their food because they turn sunlight into food energy through photosynthesis. Leaves also make the oxygen in the air that we breathe.

Flowers
Flowers generally are the showiest part of a plant. Their beauty and fragrance attract pollinators (insects or birds) that play an important role in the reproductive process.
