Cell Energy Cycle 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, using carbon dioxide and water.

Front

What is the main product of photosynthesis?

Back

The main products of photosynthesis are glucose and oxygen.

Front

What gas do plants take in during photosynthesis?

Back

Plants take in carbon dioxide (CO2) during photosynthesis.

Front

What gas do plants release during photosynthesis?

Back

Plants release oxygen (O2) during photosynthesis.

Front

What is the role of chlorophyll 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 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 light intensity affect the rate of photosynthesis?

Back

In general, as light intensity increases, the rate of photosynthesis increases, up to a certain point, after which it levels off.

Front

What is the equation for photosynthesis?

Back

The equation for photosynthesis is: carbon dioxide + water → glucose + oxygen.

Front

What is the importance of photosynthesis to life on Earth?

Back

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

Front

How does temperature affect photosynthesis?

Back

Temperature affects the rate of photosynthesis; generally, higher temperatures increase the rate, but extreme temperatures can inhibit the process.
