if stomatal index of a leaf is 25 and epidermal cells per unit area is 30, find the number of stomata per unit area
Answers
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.
