Fibres are likely to be absent in
1 secondary phloem
2 secondary xylem
3 primary phloem
4 leaves
Explanation:
(d)Leaves The leaves of the plants are mainly the organ of photosynthesis. It has specialized parenchymatous cells having chlorophyll. It does not have any fibrous cells.

Root hairs develop from the region of
1 maturation
2 elongation
3 root cap
4 meristematic activity
Explanation:
(b)The root is covered at the apex. A few millimeters above the root cap is the region of meristematic activity. The cells of this region are very small, thin-walled and with dense protoplasm. They divide repeatedly. The cells proximal to this region undergo rapid elongation and enlargement and are responsible for the growth of the root in length. This region is called the region of elongation. Root hairs arise from this region.

The quiescent centre in root meristem serves as a
1 site for storage of food, which is utilised during maturation.
2 reservoir of growth hormones.
3 reserve for replenishment of damaged cells of the meristem.
4 region for absorption of water.
Explanation:
(c)Quiescent centre having low rate of cell division & acts as reservoirs of active initials for replenishment of damaged cells of meristem.
