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 main source of energy for photosynthesis?

Back

The main source of energy for photosynthesis is the sun.

Front

What do plants produce during photosynthesis?

Back

Plants produce glucose (food) and oxygen during photosynthesis.

Front

What are stomata?

Back

Stomata are tiny openings on the surface of leaves that allow gases, such as carbon dioxide and oxygen, to enter and exit the plant.

Front

What is the chemical equation for photosynthesis?

Back

6CO2 + 6H2O + Light Energy → C6H12O6 + 6O2.

Front

What role does chlorophyll play in photosynthesis?

Back

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

Front

What is the importance of photosynthesis for life on Earth?

Back

Photosynthesis is crucial because it produces oxygen, which is necessary for the survival of most living organisms, and it forms the base of the food chain.

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 do plants obtain water for photosynthesis?

Back

Plants obtain water through their roots from the soil.

Front

What is the role of carbon dioxide in photosynthesis?

Back

Carbon dioxide is one of the raw materials used by plants during photosynthesis to produce glucose.
