answer is
c3 cycle :-
1. it is also known as a calvinmelvin cycle .
2. it seen in all photosynthetic plants and it common in plants.
3. it occurs only in mesophyll cells mainly.
4. it involves three process namely carboxylation , reduction , regeneration.
5. during this cycle RUBISCO enzyme is used .
6. during Calvin cycle 3 molecules of ATP And 2 moles of NADH is used .
7. 1st formed product is three carbon called PEP phosphophenol pyruvic acid .
c4 cycle :-
1. it occurs in both the cells like mesophyll cells and bundle sheath cells .
2. the first formed product is OAA I.e oxaloacetic acid .
3. it does not occur in all photosynthetic plants .
4. it is seen in sorghum, sugarcane and maize etc,.
4. during this cycle 30 ATP and 12 BADH IS used.
5. during this process in maximum cells the RUBISCO enzyme is absent but PEPCASE enzyme is present.
6. in bundle sheath cells the RUBISCO enzyme is present and again it leads to c3 cycle.
I hope My answer will help u ..^_^

ANSWER.....
====================================
☆☆ C3 CYCLE IN PLANTS ☆☆
====================================
▪ Photosynthesis occurs in mesophyll cells .
▪ Kranz Anatomy is absent here.
▪ RuBP is the primary CO2 acceptor.
▪ 3-PGA, a 3-C compound is the first stable product.
▪ Chloroplasts are only one type. [ granal ]
▪ Highly loss of photorespiration.
▪ High CO2 compensation point.
▪ Optimum temperature for photosynthesis is absent 25°C.
▪ Photosynthetically less efficient & productivity low.
¤¤ For Example --- Rice, Wheat, Bean, Potato.
====================================
☆☆ C4 CYCLE IN PLANTS ☆☆
====================================
▪ Photosynthesis occurs in mesophyll and bundle sheath cells.
▪ Kranz Anatomy is Present.
▪ PEP is the primary CO2 Acceptors .
▪ OAA, a 4-C compounds is the first stable product.
▪ Chloroplasts are dimorphic.
▪ Photorespiration is absent or negligible.
▪ Low CO2 compensation point.
▪ Optimum temperature for photosynthesis is about 35°C - 45°C.
▪ Photosynthetically more efficient and productivity is high.
¤¤ For Example ---- Maize , Sugercane , Amaranth, Sorghum.
