Question

Tabulate any eight differences between C3 and C4 pathways/ plants.

Answer 1

C3 cycle
1.use Calvin cycle for dark reaction of photosynthesis.
2.ex. wheat, oat, rice, cotton
3.first stable product is 3 carbon compound phosphoglyceric acid.
4. 95% of total green plants are show C3 pathway
5. abundant in temperate condition
6. do not have kranz anatomy
7. bundle sheath do not contain chloroplast ,and do not contain peripheral reticulum
8. have one CO2 accepter


C4 pathway
1. use hatch pathway of photosynthesis
2. ex. maize, sorghum, sugarcane
3.first stable product of C4 pathway is 4 carbon oxaloacetic acid
4. 5% of total plants are showing C4 pathway
5. abundant in tropical condition
6. show kranz anatomy
7. bundle sheath contain chloroplast and chloroplast contain peripheral reticulum
8. have primary, secondary CO2 acceptor
