Question

differentiate between respiration and photorespiration

Answer 1

Photo respiration -
1.It occurs only inside photosynthetic cells.

2. Photorespiration takes place only in the presence of light.

Respiration -
1. It is found in all living cells.

2. This type of respiration continues both in dark and light.

Answer 2

Respiration and photo respiration

Explanation:

Photo respiration:

1. It occurs only inside photosynthetic cells.  

2. Photorespiration takes place only in the presence of light.  

3. It is pronounced in C3 plants and negligible in C4 plants.  

4. In photo respiration uptake of oxygen and evolution of carbon dioxide is light-dependent.

5. It occurs in the chloroplasts and may require the help of peroxisomes and mitochondria.

Respiration:

1. It occurs in all living cells

2. This type of respiration continues both in dark and light.

3. Exchange of gases is independent of light.  

4.. It is not influenced by the change in oxygen concentration between 10-25%. Beyond it there is a decline in the rate of respiration.  

5. It occurs in cytoplasm and mitochondria.
