Photosynthesis Study Guide

Front

What is the net flow of gases during photosynthesis?

Back

Carbon dioxide moves into the plant cells, and oxygen moves out.

Front

What molecule is absorbed at the beginning of the second step of photosynthesis?

Back

CO2 (carbon dioxide)

Front

Which substance is NOT a reactant in the process of photosynthesis?

Back

Glucose

Front

What are the photosynthetic reactions that do not require light called?

Back

Light-independent reactions (Calvin cycle)

Front

What is the name of the green pigment that absorbs light in the chloroplasts?

Back

Chlorophyll

Front

What are the two main stages of photosynthesis?

Back

Light-dependent reactions and light-independent reactions (Calvin cycle).

Front

Where do light-dependent reactions occur in the chloroplast?

Back

In the thylakoid membranes.

Front

What is the primary purpose of light-dependent reactions?

Back

To convert solar energy into chemical energy (ATP and NADPH).

Front

What is produced as a byproduct of photosynthesis?

Back

Oxygen (O2).

Front

What is the role of chlorophyll in photosynthesis?

Back

To absorb light energy, primarily in the blue and red wavelengths.
