Photosynthesis & Cell 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 function of chlorophyll in photosynthesis?

Back

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

Front

What is the overall equation for photosynthesis?

Back

The overall equation for photosynthesis is: Carbon dioxide + Water → Glucose + Oxygen.

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

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 relationship between photosynthesis and cellular respiration?

Back

Photosynthesis and cellular respiration are interconnected processes; photosynthesis converts carbon dioxide and water into glucose and oxygen, while cellular respiration uses glucose and oxygen to produce energy, carbon dioxide, and water.

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 happens to the glucose produced during photosynthesis?

Back

The glucose produced during photosynthesis can be used immediately for energy, stored as starch for later use, or used to build other organic molecules.

Front

What role do stomata play in photosynthesis?

Back

Stomata are small openings on the surface of leaves that allow for the exchange of gases; they enable carbon dioxide to enter the leaf and oxygen to exit.

Front

What is the role of water in photosynthesis?

Back

Water is a reactant in photosynthesis; it provides electrons and protons needed for the formation of glucose and is split during the light-dependent reactions.
