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, and releasing oxygen as a byproduct.

Front

What is the main product of photosynthesis?

Back

The main product of photosynthesis is glucose (C6H12O6), which serves as an energy source for the plant.

Front

What is respiration in plants?

Back

Respiration is the process by which plants convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What are the two main stages of photosynthesis?

Back

The two main stages of photosynthesis are the light-dependent reactions and the light-independent reactions (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 green pigment in chloroplasts that absorbs light energy, primarily from the sun, to drive 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 the role of mitochondria in plant cells?

Back

Mitochondria are the powerhouses of the cell, where respiration occurs, converting glucose into ATP (energy) for cellular activities.

Front

What is ATP and why is it important?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, providing energy for various cellular processes.

Front

What is the relationship between photosynthesis and respiration?

Back

Photosynthesis produces glucose and oxygen, which are used in respiration to produce ATP, while respiration releases carbon dioxide and water, which are used in photosynthesis.
