Question

1. all of the following are steps of photosynthesis except:

a. chlorophyll is absorbed through plant roots.
b. during photolysis a photon of light is absorbed by the chlorophyll pigment,
which then is in an excited (higher energy) state.
c. water is separated into hydrogen and oxygen atoms.
d. an adp molecule is phosphorylated to atp.

Explanation:

• Chlorophyll is a pigment produced by the plant itself, not absorbed through roots.
• Option B is a valid step in the light - dependent reactions (photolysis).
• Option C occurs during the splitting of water in the light - dependent reactions.
• Option D (ADP phosphorylation to ATP) is a key part of the light - dependent reactions.

Answer:

A. Chlorophyll is absorbed through plant roots.
