Question

The rate of photosynthesis carried on by plants living in a body of water depends upon the
a. oxygen content of the water
b. amount of light that penetrates the water
c. nitrogen content of the water
d. elevation of the body of water​

Answer 1

B

plants need light(sunlight),carbon(iv)oxide to photosynthesize

Answer 2

b. amount of light that penetrates the water

Rate of photosynthesis depends upon:

1. Light intensity,
2. carbon dioxide concentration, and
3. temperature.

The rate of photosynthesis carried on by plants living in a body of water depends upon the amount of light that penetrates the water.

• The rate of the light-dependent reaction, and hence photosynthesis in general, increases proportionately as the light intensity increases.

Thus, correct option is b.
