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 are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose and oxygen.

Front

What is respiration in living organisms?

Back

Respiration is the biochemical process in which cells convert glucose and oxygen into energy, carbon dioxide, and water.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is the green pigment in plants that absorbs light energy, primarily from the sun, to facilitate photosynthesis.

Front

Where does photosynthesis occur in plant cells?

Back

Photosynthesis occurs in the chloroplasts of plant cells.

Front

What is the equation for photosynthesis?

Back

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

Front

What is the main source of energy for all life on Earth?

Back

The main source of energy for all life comes from the sun.

Front

What are mitochondria and their function?

Back

Mitochondria are organelles in cells that produce energy through respiration, converting glucose and oxygen into ATP (adenosine triphosphate).

Front

Why do muscle cells have many mitochondria?

Back

Muscle cells have many mitochondria because they require a lot of energy for contraction and movement.

Front

What is lactic acid and when is it produced?

Back

Lactic acid is a byproduct of anaerobic respiration, produced when muscles undergo intense activity and oxygen levels are low.
