Photosynthesis and Respiration GATE

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 is cellular respiration?

Back

Cellular respiration is the process by which cells obtain energy from glucose, breaking it down in the presence of oxygen to produce carbon dioxide, water, and energy (ATP).

Front

What is the role of sunlight in photosynthesis?

Back

Sunlight provides the energy needed to convert carbon dioxide and water into glucose and oxygen during photosynthesis.

Front

What are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the Light Reactions (Stage 1) and the Calvin Cycle (Dark Reactions, Stage 2).

Front

Where does photosynthesis occur in plant cells?

Back

Photosynthesis occurs in the chloroplasts of plant cells.

Front

What is the chemical equation for photosynthesis?

Back

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

Front

What is the primary product of photosynthesis?

Back

The primary product of photosynthesis is glucose (C6H12O6).

Front

What is the significance of chlorophyll in photosynthesis?

Back

Chlorophyll is the green pigment in plants that absorbs light energy, primarily from the sun, which is essential for photosynthesis.

Front

What is the difference between aerobic and anaerobic respiration?

Back

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

Front

What is the role of the stomata in plants?

Back

Stomata are small openings on the surfaces of leaves that allow for gas exchange, enabling carbon dioxide to enter and oxygen to exit.
