Photosynthesis

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy in the form of glucose, using carbon dioxide and water.

Front

What is the primary source of energy for photosynthesis?

Back

The primary source of energy for photosynthesis is sunlight.

Front

What are autotrophs?

Back

Autotrophs are organisms that can produce their own food from inorganic substances, using light or chemical energy.

Front

What are heterotrophs?

Back

Heterotrophs are organisms that cannot produce their own food and must obtain it by consuming other living or once-living things.

Front

What is the role of chloroplasts in photosynthesis?

Back

Chloroplasts are the organelles in plant cells where photosynthesis takes place, 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 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

What happens during the light-dependent reactions?

Back

During the light-dependent reactions, sunlight is absorbed by chlorophyll, water is split, and energy carriers ATP and NADPH are produced.

Front

What is the Calvin cycle?

Back

The Calvin cycle is the light-independent stage of photosynthesis where carbon dioxide is fixed into glucose using ATP and NADPH.

Front

What is the equation for photosynthesis?

Back

The equation for photosynthesis is: 6CO2 + 6H2O + light energy → C6H12O6 + 6O2.
