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, 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, which plants use for energy.

Front

What gas do plants release during photosynthesis?

Back

Plants release oxygen as a byproduct of photosynthesis.

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

When do plants perform photosynthesis?

Back

Plants perform photosynthesis mainly during the daytime when there is sunlight.

Front

Why can't humans perform photosynthesis?

Back

Humans cannot perform photosynthesis because our cells do not contain chloroplasts, which are necessary for the process.

Front

What is the relationship between photosynthesis and respiration?

Back

Photosynthesis produces oxygen and glucose, which are used in cellular respiration to release energy, while respiration produces carbon dioxide and water, which are used in photosynthesis.

Front

What is the equation for photosynthesis?

Back

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

Front

What is the importance of photosynthesis to life on Earth?

Back

Photosynthesis is crucial because it provides oxygen for living organisms and is the foundation of the food chain.
