B-LS1-5 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 are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose and oxygen.

Front

What is the role of sunlight in photosynthesis?

Back

Sunlight provides the energy needed for photosynthesis to occur, enabling plants to convert carbon dioxide and water into glucose and oxygen.

Front

Which gas do plants absorb during photosynthesis?

Back

Plants absorb carbon dioxide during photosynthesis.

Front

What is the chemical equation for photosynthesis?

Back

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

Front

What is the significance of glucose in plants?

Back

Glucose serves as an energy source for plants and is used to build other organic compounds necessary for growth and development.

Front

Do all plants perform photosynthesis?

Back

No, not all plants perform photosynthesis. Some plants, like parasitic plants, obtain nutrients from other organisms.

Front

What is chlorophyll and its role in photosynthesis?

Back

Chlorophyll is a green pigment found in the chloroplasts of plants that absorbs light energy, primarily from the sun, to drive the photosynthesis process.

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

How does temperature affect photosynthesis?

Back

Temperature can affect the rate of photosynthesis; higher temperatures can increase the rate up to a certain point, after which it may decrease due to enzyme denaturation.
