Question: 95. In the given figure, which component has thin outer walls and highly thickened inner walls?
(1) C
(2) D
(3) A
(4) B
Answer: Option (1)
Explanation:
The given figure represents a stomatal apparatus found in the epidermis of a leaf.
In the stomatal apparatus, guard cells are specialized cells that surround the stomatal pore.
Guard cells have a unique wall structure in which the outer walls are thin and elastic,
while the inner walls facing the stomatal pore are highly thickened.
This differential wall thickness helps guard cells change shape during opening and closing of the stomata.
In the given figure, the component labeled C represents the guard cell.
Therefore, the component with thin outer walls and highly thickened inner walls is C.
