Unit 5 Photosynthesis Flashcard Review

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water.

Front

What are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the light-dependent reactions and the light-independent reactions (Calvin cycle).

Front

Where do light-dependent reactions occur?

Back

Light-dependent reactions occur in the thylakoid membranes of chloroplasts.

Front

What is produced during light-dependent reactions?

Back

Light-dependent reactions produce ATP, NADPH, and oxygen.

Front

Where do light-independent reactions take place?

Back

Light-independent reactions take place in the stroma of chloroplasts.

Front

What is the main product of the light-independent reactions?

Back

The main product of the light-independent reactions is glucose.

Front

How does temperature affect the rate of photosynthesis?

Back

As temperature increases, the rate of photosynthesis generally increases up to a certain point, after which it may decrease due to enzyme denaturation.

Front

What role do stomata play in photosynthesis?

Back

Stomata are small openings on the leaf surface that allow for gas exchange; they enable carbon dioxide to enter and oxygen to exit.

Front

What is the relationship between light intensity and photosynthesis?

Back

As light intensity increases, the rate of photosynthesis increases until it reaches a saturation point.

Front

What gas is produced as a byproduct of photosynthesis?

Back

Oxygen is produced as a byproduct of photosynthesis.
