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

Only Autotrophs, such as plants and algae, perform photosynthesis.

Front

What is the main pigment involved in Photosynthesis?

Back

Chlorophyll is the pigment in chloroplasts that captures light energy for photosynthesis.

Front

What do plants give off during Photosynthesis?

Back

Plants give off oxygen during photosynthesis.

Front

What do animals give off that plants need?

Back

Animals give off carbon dioxide, which plants need for photosynthesis.

Front

What happens to the atoms in water and carbon dioxide during Photosynthesis?

Back

The atoms in water and carbon dioxide rearrange to form oxygen and glucose.

Front

What is the role of sunlight in Photosynthesis?

Back

Sunlight provides the energy needed to drive the chemical reactions of 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

Where does Photosynthesis occur in plant cells?

Back

Photosynthesis occurs in the chloroplasts of plant cells.

Front

What is the chemical equation for Photosynthesis?

Back

6CO2 + 6H2O + light energy → C6H12O6 + 6O2.
