Q961
Compensation point is the value of a factor where there is
A.
Beginning of photosynthesis
B.
Little photosynthesis
C.
Photosynthesis equal to rate of respiration
AnswerD.
Neither photosynthesis nor respiration
Answer: Option C
Solution
Answer: Option C
Solution:
The compensation point is the value of a factor where there is photosynthesis equal to the rate of respiration.The light compensation point (Ic) is the light intensity on the light curve where the rate of photosynthesis exactly matches the rate of cellular respiration.
At this point, the uptake of CO2 through photosynthetic pathways is equal to the respiratory release of carbon dioxide, and the uptake of O2 by respiration is equal to the photosynthetic release of oxygen.
