Question

Match each item to indicate whether it is a description of photosynthesis or cellular respiration.

a. Photosynthesis
b. Cellular Respiration
1. Produces a necessary gas for humans.
2. Occurs in the chloroplasts.
3. Occurs in both plant and animal cells.
4. Occurs in the mitochondria.

Answer 1

Photosynthesis occurs in chloroplasts and produces oxygen and glucose, whereas cellular respiration occurs in mitochondria of both plants and animals, using that oxygen and glucose to produce carbon dioxide, water, and ATP, which are then used in photosynthesis.

Step-by-step explanation:

Match each item to indicate whether it is a description of photosynthesis or cellular respiration:

1. Cellular Respiration: Produces a necessary gas for humans (oxygen).
2. Photosynthesis: Occurs in the chloroplasts.
3. Cellular Respiration: Occurs in both plant and animal cells.
4. Cellular Respiration: Occurs in the mitochondria.

Photosynthesis and cellular respiration occur at the same time in a plant. Photosynthesis, occurring in chloroplasts, makes glucose and oxygen, which are then used as starting products for cellular respiration, which takes place in the mitochondria. Cellular respiration creates carbon dioxide and water (and ATP), which are used as starting products (along with sunlight) for photosynthesis, forming a cyclical relationship.

Cellular respiration and photosynthesis are interdependent processes that form the basis of the energy cycle within plant cells that contain both chloroplasts and mitochondria.
