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

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
