Photosynthesis and Cellular respiration

1. What is chlorophyll and how does it help plants?

• A.Chlorophyll is a pigment that absorbs light energy and makes glucose.

• B.Chlorophyll is a protein that changes shape in the presence of sunlight.

• C.Chlorophyll is a receptor that binds carbon dioxide when energized by light

• D.Chlorophyll is an enzyme that catalyzes the production of glucose when exposed to light.

Choose the correct order of the two stages of photosynthesis.

• 1st stage is Light-Dependent Reactions. 2nd stage is Dark Reactions.

• 1st stage is Dark Reactions. 2nd stage is Light-Dependent Reactions.

Pick the 2 options that show where the two stages of photosynthesis occur.

• Dark Reactions (Calvin Cycle) - in the stroma

• Light-Dependent Reactions - on the thylakoid

• Dark Reactions (Calvin Cycle) - on the thylakoid
