Question

Difference between c3 and c4 plants...... ​

Answer 1

HEYA GM ^_^

# Photosynthesis...

- C3 pathway occurs in Stroma of chloroplast of Mesophyll cells... While C4 occurs in GRANUM THYLAKOIDS...

- C3 has RUBISCO while C4 has Both but most efficient PEP

- Synthesize of PGA ( 3-C COMPOUND) so formed as First stable compound on C3 so DUE TO 3-C +CE it is called as C3 cycle

- Synthesize of OXALOACETIC ACID ( OAA - 4C COMPOUND) SO due to presence of 4 carbon it is known as C4 cycle,..

THANK YOU... ^_^

Explanation:

$\huge\underline\mathfrak\blue{Answer}$

★C3 plant -

1. Obtimum temprature for photosynthesis 10° to 25°C.
2. The leaves do not posses kranz anatomy.
3. Chloroplast are of one type ( monomorphic).
4. Bundle sheath cell usually do not contain chloroplast.
5. RUBP is first acceptor of CO2.
6. PGA is the first stable product which is 3 carbon compound.
7. Plants operate only calvin cycle.
8. Rate of carbon assimilation is slow
9. Rate of photosynthesis is high.
10. The cycle operate in all plants.

★C4 plant -

1. Obtimum temprature for photosynthesis is 30° to 45°.
2. The leaves have kranz anatomy.
3. There are 2 types of chloroplast.
4. Bundel sheath cell contains chloroplast.
5. PEP is the first acceptor of CO2.
6. Oxaloacetic acid is the first product which is 4 carbon compound.
7. Plants operate C4 cycle in addition to calvin cycle.
8. Rate of carbon assimilation is rapid.
9. Rate of photorespiration is neglegible.
10. The cycle is found only in some plants.
