Answer: 90 stomata per unit area.

Explanation: Here stomatal index (I) = 25

Epidermal cell per unit area ( S) = 30

No. Of stomata per unit area( E) =?

Using formula

I= s/ (E+S)*100

25 = 30/(E+30)*100

25(E+30)=30*100

25E+750= 3000

25 E = 3000-750

25E = 2250

E= 2250/25

E = 90

Answer:

Stomatal number is classified as the average number of stomata in the leaf epidermis per sq mm.

Explanation:

Stomatal index is defined as the percentage of the total number of epidermal cells produced by the number of stomata, where each stoma is counted as a single cell.

Stomatal index is calculated by using this equation:

Stomatal Index (I) = S x 100/E+S

Given:

stomatal index (I) = 25

Epidermal cell per unit area ( S) = 30

No. Of stomata per unit area( E) =?

Put the given values in the equation:

25 = 30 x 100/E+30

25 (E+30) = 30 x 100

25E +750 = 3000

25 E = 3000 - 750

25E = 2250  

E= 2250/25

E = 90

Hence,  No. Of stomata per unit area is 90.
