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. It occurs in both plants and animals.

Front

What is the main difference between photosynthesis and cellular respiration?

Back

Photosynthesis uses carbon dioxide and produces oxygen, while cellular respiration uses oxygen and produces carbon dioxide.

Front

What is the role of the stoma in plants?

Back

The stoma is a small opening on the surface of leaves that allows carbon dioxide to enter and oxygen and water vapor to exit.

Front

What is xylem?

Back

Xylem is the water transport system in plants that carries water and dissolved minerals from the roots to the leaves.

Front

What is the formula for photosynthesis?

Back

6 H₂O + 6 CO₂ → C₆H₁₂O₆ + 6 O₂.

Front

What is the formula for cellular respiration?

Back

C₆H₁₂O₆ + 6 O₂ → 6 H₂O + 6 CO₂.

Front

Do plants only perform photosynthesis?

Back

No, plants perform both photosynthesis and cellular respiration.

Front

What is ATP?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, used to store and transfer energy for various cellular processes.

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 drive the process of photosynthesis.
