Select the correct statements.
I. From the region of elongation, some of the epidermal cells form root hairs.
II. Pneumatophores are seen in Rhizophora.
III. Adventitious roots are seen in the banyan tree.
IV. Maize and sugarcane have prop roots.
II and III
In some plants such as Rhizophora growing in swampy areas, many roots come out of the ground and grow vertically upwards. Such roots are called pneumatophores. They help to get oxygen for respiration.
In banyan tree, adventitious roots are hanging structures arising from nodes of horizontally growing branches. Such roots are called prop roots.
Root hairs arise from the zone of maturation.
Maize and sugarcane have adventitious roots called stilt root for support while maize usually develop adventitious roots from lower internodes.
