1.	How can you identify weather the plant is c3 or c4? explain /justify
Answer» The main difference between C3 and C4 plants is observed in their anatomical structure. If one want to identify these plants morphologically, then the most important point is the climate or area as C4 plants are grown in hot, dry climates whereas C3 plants are found in cool and wet areas.Thanks @diti?
