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 oxygen, ATP, and NADPH.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a pigment that absorbs light energy, primarily from the sun, which is essential for the light-dependent reactions of photosynthesis.

Front

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

Back

The main product of the light-independent reactions (Calvin cycle) 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 is the function of stomata in leaves?

Back

Stomata are small openings on the surface of leaves that allow for gas exchange, enabling the intake of carbon dioxide and the release of oxygen.

Front

What is the difference between light-dependent and light-independent reactions?

Back

Light-dependent reactions require light to occur, while light-independent reactions (Calvin cycle) can occur in the absence of light.

Front

What is the significance of water in photosynthesis?

Back

Water is a reactant in photosynthesis that provides electrons and protons for the light-dependent reactions and is split to release oxygen.
