Photosynthesis and Respiration Review

Front

What is photosynthesis?

Back

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

Front

What is the primary pigment involved in photosynthesis?

Back

Chlorophyll is the primary pigment involved in photosynthesis, which absorbs light energy.

Front

What do plants produce during photosynthesis?

Back

Plants produce glucose and oxygen during photosynthesis.

Front

What is respiration in living organisms?

Back

Respiration is the process by which organisms convert glucose and oxygen into energy, carbon dioxide, and water.

Front

How do plants obtain carbon dioxide for photosynthesis?

Back

Plants obtain carbon dioxide from the air through small openings in their leaves called stomata.

Front

What is the role of sunlight in photosynthesis?

Back

Sunlight provides the energy needed to drive the chemical reactions that convert carbon dioxide and water into glucose.

Front

What is the chemical equation for photosynthesis?

Back

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

Front

Why do leaves appear green?

Back

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

Front

What is the difference between photosynthesis and respiration?

Back

Photosynthesis converts light energy into chemical energy (glucose), while respiration breaks down glucose to release energy.

Front

Which organisms perform photosynthesis?

Back

Plants, algae, and some bacteria perform photosynthesis.
