Unit 5: Photosynthesis and Cellular Respiration checkpoint 2024

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy in the form of glucose, using carbon dioxide and water.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are oxygen and glucose.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a green pigment found in plants that absorbs light energy, primarily from the sun, 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 is the significance of oxygen in photosynthesis?

Back

Oxygen is a byproduct of photosynthesis and is released into the atmosphere, which is essential for the survival of aerobic organisms.

Front

What is the relationship between photosynthesis and cellular respiration?

Back

Photosynthesis converts carbon dioxide and water into glucose and oxygen, while cellular respiration uses glucose and oxygen to produce energy, carbon dioxide, and water.

Front

What factors affect the rate of photosynthesis?

Back

The rate of photosynthesis is affected by light intensity, carbon dioxide concentration, temperature, and the availability of water.

Front

Why do plants appear green?

Back

Plants appear green because chlorophyll reflects green light and absorbs other wavelengths of light for photosynthesis.

Front

What is the role of sunlight in photosynthesis?

Back

Sunlight provides the energy required for the photosynthesis process, enabling plants to convert carbon dioxide and water into glucose.
