Photosynthesis Review

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 (sugar) using carbon dioxide and water.

Front

What do plants need for photosynthesis?

Back

Plants need sunlight, carbon dioxide, and water to perform photosynthesis.

Front

What is the main product of photosynthesis?

Back

The main product of photosynthesis is glucose (sugar), which plants use for energy.

Front

What gas do plants take in during photosynthesis?

Back

Plants take in carbon dioxide during photosynthesis.

Front

What gas do plants release during photosynthesis?

Back

Plants release oxygen during photosynthesis.

Front

How does light intensity affect photosynthesis?

Back

Higher light intensity increases the rate of photosynthesis, leading to more oxygen and glucose production.

Front

What role does chlorophyll play in photosynthesis?

Back

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

Front

What is the equation for photosynthesis?

Back

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

Front

What happens to plants in the absence of sunlight?

Back

In the absence of sunlight, plants cannot perform photosynthesis, leading to a lack of energy and eventual death.

Front

What is the importance of photosynthesis to life on Earth?

Back

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