Photosynthesis and Cellular 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 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 role 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 photosynthesis.

Front

What are the main products of photosynthesis?

Back

The main products of photosynthesis are glucose (sugar) and oxygen.

Front

What are the main reactants of cellular respiration?

Back

The main reactants of cellular respiration are glucose and oxygen.

Front

What is the stoma in plants?

Back

The stoma is a small opening on the surface of leaves that allows for gas exchange; it lets carbon dioxide enter and oxygen and water vapor exit.

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

How are photosynthesis and cellular respiration related?

Back

Photosynthesis and cellular respiration are opposite 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 the significance of the light-dependent reactions in photosynthesis?

Back

The light-dependent reactions capture light energy and convert it into chemical energy (ATP and NADPH) and produce oxygen as a byproduct.

Front

What is the significance of the light-independent reactions (Calvin Cycle) in photosynthesis?

Back

The light-independent reactions (Calvin Cycle) use ATP and NADPH from the light-dependent reactions to convert carbon dioxide into glucose.
