Photosynthesis and Respiration

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 the primary source of energy for photosynthesis?

Back

The primary source of energy for photosynthesis is sunlight.

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

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a green pigment found in plants that absorbs light energy, primarily from the blue and red wavelengths, to drive the photosynthesis process.

Front

What is the Calvin Cycle?

Back

The Calvin Cycle is the set of chemical reactions that take place in chloroplasts during photosynthesis, where carbon dioxide is converted into glucose using ATP and NADPH produced in the light reactions.

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

What is the main purpose of cellular respiration?

Back

The main purpose of cellular respiration is to produce ATP, which is used as energy by cells.

Front

What are autotrophs?

Back

Autotrophs are organisms that can produce their own food from inorganic substances, using light (photosynthesis) or chemical energy (chemosynthesis).

Front

What are heterotrophs?

Back

Heterotrophs are organisms that cannot produce their own food and must consume other organisms or organic matter for energy.

Front

What is the equation for photosynthesis?

Back

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