Subject: Biology, asked on 8/7/18

How does:
i) the thickness of cuticle
ii) the distribution of stomata
iii) the size of the leaf
influence the amount of light and the amount of CO2 entering the leaf?
Please mention whether they are directly or inversely proportional to the factors mentioned above.

Please solve q.9

Subject: Biology, asked on 3/5/18

Plz EXPLAIN:
The graph shows the relation between influence of light intensity of CO2 concentration on the rate of photosynthesis of Chlorella:
​Which on of the following statements explains the diagram correctly?
(A) At low light intensity, the light- dependent reaction is rate limiting but at high light intensity, CO2 is rate limiting
(B) The number of chlorophyll molecules limits the rate of photosynthesis.
(C) Photosynthesis is independent of light intensity provided there is not total darkness.
(D) Chlorophyll responds equally to light intensities and CO2 concentrations, thereby limiting the rate of photosynthesis.
