1) What is c4 plants?
C4 plants use additional cycle(C4 Cycle) so it can do dark reaction in small amount of CO2. Because 4-carbon oxalate is first fixed product so this cycle name is `C4 cycle` and found at 1966 by 2 Australians Hatch and slack. So this cyle also called Hatch-Slack cycle. This cycle is fixed CO2 more effectively than Rubisco of calvin cycle(C3 Cycle).
C4 plants possess biochemical and anatomical mechanisms to raise the intercellular carbon dioxide concentration at the site of fixation, and this reduces, and sometimes eliminates, carbon losses by photorespiration. C4 plants, which inhabit hot, dry evironments, have very high water-use efficiency, so that there can be up to twice as much photosynthesis per gram of water as in C3 plants, but C4 metabolism is inefficient in shady or cool environments. Less than 1% of earth`s plant species can be classified as C4.
