Now let's go down to the root part of the plant. Primary roots of all green plants are very much alike. The differences appear as the roots grow. In some plants, the fully grown roots are shaped very much like their primary roots. Such roots are called taproots.
Taproots are the longest and the strongest of the different kinds of roots.
Thin roots usually grow along the sides of the taproots. Fibrous roots are formed when the primary roots grow many branches. The size of fibrous roots remains small as compared to taproots. Almost all of the growing parts of fibrous roots have root hairs near the tips. Things like grasses, beans, roses, and apple trees have fibrous roots.
