Q. Factors affecting photosynthesis are I. number and size of leaves II. age and orientation of leaves III. amount of chlorophyll IV. amount of $O_{2}$ and $CO_{2}$ Select the correct option
A) I, II and IV
B) II, IV and V
C) IV, V and I
D) I, II, III and IV
Explanation
The rate of photosynthesis is very important in determining the yield of plants including crop plants. Photosynthesis is under the influence of several factors, both internal (plant) and external. The plant factors includes the number, size, age and orientation of leaves, mesophyll cells and chloroplast, internal $CO_{2}$ concentration and the amount of chlorophyll. The plant or internal factors are dependent on the genetic predisposition and the growth of the plant
