The cork is impervious to water due to ____ deposited in the ____
1 Lignin, cell wall
2 Cellulose, cell wall
3 Suberin, cell wall
4 Suberin, cell membrane
Explanation:
The thin walls of cork cells are saturated with a fatty waxy substance called suberin which makes the cell wall of the cork thick and almost impervious to water.

Lenticel develops through the activity of
1 Vascular cambium
2 Pith
3 Phellogen
4 Intra fascicular cambium
Explanation:
At certain regions, the phellogen cuts off closely arranged parenchymatous cells on the outer side instead of cork cells. These parenchymatous cells soon rupture the epidermis, forming a lens-shaped openings called lenticels

Which of the following sequence represents secondary growth from out to inside?
1 Phellogen Phellem Phelloderm
2 Phellogen Phelloderm Phellem
3 Phellem Phellogen Phelloderm
4 Phelloderm Phellogen Phellem
Explanation:
Secondary growth by sequence from outside to inside can be shown as Phellem Phellogen - Phelloderm.
