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 products of photosynthesis?

Back

The main products of photosynthesis are oxygen and glucose.

Front

What do plants need for photosynthesis?

Back

Plants need light, carbon dioxide, and water for the process of photosynthesis.

Front

What is a heterotroph?

Back

A heterotroph is an organism that cannot produce its own food and instead obtains its nutrients by consuming other organisms. Examples include animals like bears.

Front

What is the role of chlorophyll in photosynthesis?

Back

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

Front

What happens to water and carbon dioxide during photosynthesis?

Back

During photosynthesis, the atoms in water and carbon dioxide rearrange to form glucose and oxygen.

Front

What is the equation for photosynthesis?

Back

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

Front

Why is photosynthesis important for life on Earth?

Back

Photosynthesis is important because it produces oxygen, which is essential for the survival of most living organisms, and it is the foundation of the food chain.

Front

What is the difference between autotrophs and heterotrophs?

Back

Autotrophs are organisms that can produce their own food through photosynthesis or chemosynthesis, while heterotrophs must consume other organisms for energy.
