Photosynthesis HW #3

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 (sugar) and oxygen.

Front

Which wavelengths of light are most effective for photosynthesis?

Back

Violet, blue, and green wavelengths are most effective for photosynthesis.

Front

What role does chlorophyll play in photosynthesis?

Back

Chlorophyll is the green pigment in plants that absorbs light energy, primarily in the blue and red wavelengths, to drive the photosynthesis process.

Front

How does light intensity affect the rate of photosynthesis?

Back

As light intensity increases, the rate of photosynthesis typically increases until it reaches a saturation point.

Front

What is the effect of carbon dioxide concentration on photosynthesis?

Back

Increasing carbon dioxide concentration generally increases the rate of photosynthesis, up to a certain limit.

Front

What happens to photosynthesis if carbon dioxide is removed from the environment?

Back

If carbon dioxide is removed, the rate of photosynthesis will decrease and eventually stop.

Front

What is the significance of oxygen production in photosynthesis?

Back

Oxygen produced during photosynthesis is essential for the survival of aerobic organisms, including humans.

Front

How do plants help mitigate climate change?

Back

Plants absorb carbon dioxide during photosynthesis, which helps reduce greenhouse gas levels in the atmosphere.

Front

What is the relationship between photosynthesis and respiration in plants?

Back

Photosynthesis produces glucose and oxygen, while respiration uses glucose and oxygen to produce energy, carbon dioxide, and water.
