Question

question 8 of 10
what will most likely happen to a plant that does not receive any water?
a. the light - dependent reactions will not occur.
b. the calvin cycle will produce more glucose.
c. the production of atp and nadph will increase.
d. the dark reactions will occur more quickly.

Explanation:

Water is a key reactant in the light - dependent reactions of photosynthesis. In the light - dependent reactions, water is split to release oxygen, electrons, and protons. Without water, these reactions cannot proceed. The Calvin cycle (dark reactions) depends on the products of the light - dependent reactions (ATP and NADPH). Lack of water will not cause the Calvin cycle to produce more glucose, nor will it increase ATP and NADPH production or speed up the dark reactions.

Answer:

A. The light - dependent reactions will not occur.
