Question

The numbers of stomata and epidermal cells in 1 mm2 leaf area of lower epidermis of leaves of X, Y and Z plants are given below. Arrange the plants in decreasing order of their stomatal index. (A) X Y Z (B) Y Z X (C) Z Y X (D) Y X Z

Tardigrade Admin · Accepted Answer

Stomal index (Si) =(S/S+E)× 100 where, S = Number of stomata. E = Number of epidermal cells

Q. The numbers of stomata and epidermal cells in 1 $m m^{2}$ leaf area of lower epidermis of leaves of X, Y and Z plants are given below. Arrange the plants in decreasing order of their stomatal index.

X Y Z

Y Z X

Z Y X

Y X Z

Stomal index (Si) $= \frac{S}{S + E} \times 100$ where, S = Number of stomata. E = Number of epidermal cells
