Photosynthesis

Front

What do plants use as food and a building block for growth?

Back

Glucose (sugar)

Front

Why do leaves look green?

Back

They contain a molecule named chlorophyll.

Front

What is the powerhouse of the cell that produces ATP?

Back

Mitochondria.

Front

Which organelle performs photosynthesis?

Back

Chloroplast.

Front

What happens to the rate of photosynthesis if a plant is enclosed in an air-proof bottle?

Back

It gradually slows down to zero because CO₂ is used up.

Front

What is photosynthesis?

Back

The process by which green plants use sunlight to synthesize foods with the help of chlorophyll.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy, primarily from the sun, to convert carbon dioxide and water into glucose and oxygen.

Front

What are the two main stages of photosynthesis?

Back

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

Front

What is produced during the light-dependent reactions of photosynthesis?

Back

ATP and NADPH, along with oxygen as a byproduct.

Front

What is the main purpose of the Calvin cycle?

Back

To convert carbon dioxide into glucose using ATP and NADPH produced in the light-dependent reactions.
