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

Which organisms perform photosynthesis?

Back

Organisms that perform photosynthesis include plants, algae, and some bacteria.

Front

What are the main ingredients needed for photosynthesis?

Back

The main ingredients needed for photosynthesis are light, carbon dioxide, and water.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a green pigment found in plants that absorbs light energy from the sun, which is essential for the process of photosynthesis.

Front

What type of organisms are autotrophs?

Back

Autotrophs are organisms that can produce their own food from inorganic substances, using light or chemical energy. Examples include plants and algae.

Front

What type of organisms are heterotrophs?

Back

Heterotrophs are organisms that cannot produce their own food and must consume other organisms for energy. Examples include animals and fungi.

Front

What is the byproduct of photosynthesis?

Back

The byproduct of photosynthesis is oxygen, which is released into the atmosphere.

Front

What is the chemical equation for photosynthesis?

Back

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

Front

What color of light does chlorophyll absorb the most?

Back

Chlorophyll absorbs red and blue light most effectively, but it reflects green light, which is why plants appear green.

Front

Why are plants considered autotrophs?

Back

Plants are considered autotrophs because they can produce their own food through the process of photosynthesis.
