Photosynthesis and 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 are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the Light Reactions and the Calvin Cycle.

Front

Where does photosynthesis occur in plant cells?

Back

Photosynthesis occurs in the chloroplasts of plant cells.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a pigment that absorbs light energy, primarily from the sun, which is essential for the photosynthesis process.

Front

What is the equation for photosynthesis?

Back

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

Front

What is respiration in living organisms?

Back

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

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen and produces more energy, while anaerobic respiration occurs without oxygen and produces less energy.

Front

What is the Calvin Cycle?

Back

The Calvin Cycle is the part of photosynthesis that uses carbon dioxide to produce glucose, occurring in the stroma of chloroplasts.

Front

Who was Van Helmont and what was his experiment?

Back

Van Helmont was a scientist who conducted an experiment to show that plants gain mass from water, not soil, by measuring the mass of soil before and after growing a tree.

Front

What is the primary product of photosynthesis?

Back

The primary product of photosynthesis is glucose.
