Photorespiration

During photorespiration, the oxygen consuming reaction(s) occur in:

1. stroma of chloroplasts and mitochondria

2. stroma of chloroplasts and peroxisomes

3. grana of chloroplasts and peroxisomes

4. stroma of chloroplasts

A process that makes an important difference between C₃ and C₄ plants is:

1. Transpiration

2. Glycolysis

3. Photosynthesis

4. Photorespiration

The correct sequence of cell organelles during photorespiration is:

1. chloroplast-Golgi bodies-mitochondria

2. chloroplast-rough endoplasmic reticulum-dictyosomes

3. chloroplast-mitochondria-peroxisome

4. chloroplast-vacuole-peroxisome

The process which makes a major difference between C₃ and C₄ plants is:

1.	glycolysis	2.	Calvin cycle
3.	photorespiration	4.	respiration

Given below are two statements:

Statement I:	In plants, some binds to hence fixation is decreased.
Statement II:	In plants, mesophyll cells show very little photorespiration while bundle sheath cells do not show photorespiration.

In the light of the above statements, choose the correct answer from the option given below:

1.	Both Statement I and Statement II are False
2.	Statement I is True but Statement II is False
3.	Statement I is False but Statement II is True
4.	Both Statement I and Statement II are True
