3 Photosynthesis and Cellular Respiration

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

TRUE or FALSE: Plants use both photosynthesis and respiration.

Back

True

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, to drive the process of photosynthesis.

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose and oxygen.

Front

What is the chemical equation for photosynthesis?

Back

6CO2 + 6H2O + light energy → C6H12O6 + 6O2.

Front

What is the significance of oxygen in photosynthesis?

Back

Oxygen is released as a byproduct of photosynthesis and is essential for the survival of aerobic organisms.

Front

What is the primary function of the thylakoids in chloroplasts?

Back

Thylakoids are membrane-bound structures in chloroplasts where the light-dependent reactions of photosynthesis occur.

Front

What does H2O represent in biological terms?

Back

H2O represents water, which is a crucial reactant in the process of photosynthesis.

Front

What is the relationship between photosynthesis and cellular respiration?

Back

Photosynthesis converts light energy into chemical energy stored in glucose, while cellular respiration breaks down glucose to release energy for cellular activities.
