Photosynthesis GATE

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 is the chemical equation for photosynthesis?

Back

6 CO2 + 6 H2O --> C6H12O6 + 6 O2

Front

What role do chloroplasts play in photosynthesis?

Back

Chloroplasts are the organelles in plant cells where photosynthesis occurs, containing chlorophyll that captures light energy.

Front

What is chlorophyll?

Back

Chlorophyll is a green pigment found in chloroplasts that absorbs light energy for photosynthesis.

Front

What do plants take in during photosynthesis?

Back

Plants take in carbon dioxide (CO2) and water (H2O) during photosynthesis.

Front

What do plants release after photosynthesis?

Back

Plants release oxygen (O2) as a byproduct of photosynthesis.

Front

What is the importance of photosynthesis?

Back

Photosynthesis is crucial for life on Earth as it produces oxygen and organic compounds that serve as food for most living organisms.

Front

What is the light-dependent reaction?

Back

The light-dependent reaction is the first stage of photosynthesis where light energy is converted into chemical energy (ATP and NADPH) and oxygen is released.

Front

What is the light-independent reaction (Calvin Cycle)?

Back

The light-independent reaction, also known as the Calvin Cycle, is the second stage of photosynthesis where ATP and NADPH are used to convert carbon dioxide into glucose.

Front

Why are chloroplasts not found in animal cells?

Back

Chloroplasts are not found in animal cells because animals do not perform photosynthesis.
