Photosynthesis

Front

What is the fluid-like material that surrounds the stack of thylakoids in chloroplasts?

Back

Stroma

Front

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

Back

The rate gradually slows down to zero because CO₂ is used up.

Front

Why are plants usually green?

Back

Because the chlorophyll reflects green light.

Front

Where does the Calvin Cycle (light independent reaction) take place?

Stroma

Front

Which condition would decrease the rate of photosynthesis in a plant?

Back

Changing the daylight hours from 14 hrs to 10 hrs.

Front

What is photosynthesis?

Back

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

Front

What are the main products of photosynthesis?

Back

Glucose and oxygen.

Front

What role does chlorophyll play in photosynthesis?

Back

Chlorophyll absorbs light energy, primarily from the blue and red wavelengths, to drive the photosynthesis process.

Front

What are thylakoids?

Back

Membrane-bound compartments inside chloroplasts where the light-dependent reactions of photosynthesis occur.

Front

What is the significance of the light-dependent reactions?

Back

They convert solar energy into chemical energy in the form of ATP and NADPH.
