Photosynthesis light and Calvin

What is photosynthesis?

The process by which plants convert light energy into chemical energy stored in glucose.

Where does photosynthesis occur?

In the chloroplasts of plant cells, primarily in the leaves.

True or false: Oxygen is a product of photosynthesis.

True, because during photosynthesis, oxygen is released as a byproduct.

What are the two main stages of photosynthesis?

Light reactions and the Calvin cycle.

Difference between light reactions and Calvin cycle

Light reactions capture energy; Calvin cycle uses it to synthesize glucose.

Fill in the blank: Photosynthesis converts _____ energy to ______ energy.

light; chemical

What captures light energy in plants?

Chlorophyll, a green pigment located in chloroplasts.

What is the role of water in light reactions?

Water is split to provide electrons and produce oxygen.

What happens during the Calvin cycle?

Carbon dioxide is fixed into glucose using ATP and NADPH from light reactions.

True or false: The Calvin cycle requires sunlight directly.

False, because it uses energy stored in ATP and NADPH.

What is produced in light reactions?

ATP, NADPH, and oxygen as a byproduct.

Which organelle is crucial for photosynthesis?

Chloroplasts, which contain the necessary pigments and enzymes.

What is a photon?

A particle of light energy that drives the light reactions.

What is carbon fixation?

The process of converting carbon dioxide into organic compounds in the Calvin cycle.

What is the sugar produced in photosynthesis?

Glucose, which is used by plants for energy and growth.

Fill in the blank: The light reactions occur in the _______ membrane.

thylakoid
