Current Question (ID: 12271)

Question:

Rearrange the following zones as seen in the root in the vertical section and choose the correct option: I: Root hair zone, II: Zone of meristems, III: Root cap zone, IV: Zone of maturation, V: Zone of elongation

Options:

1. III, II, V, I, IV
2. I, II, III, IV, V
3. IV, V, I, III, II
4. V, IV, III, II, I

Solution:

Root Cap Zone: protective covering at the root apex, secretes mucilage to soften the hard soil for the growth of root. Zone of Meristem: region of actively dividing densely packed cells resulting into root growth. Zone of Elongation: divided cells grow in size and elongate increasing the length of root. They cannot divide further. Root Hair Zone: root hair arises and grow in this region, helps in water and mineral absorption from the soil. Zone of Maturation: the cells of root at this region are fully differentiated and mature, performing different functions of root.
