C3 and C4 plants are named after the number of carbon molecules in the first products of their carbon fixation cycles.
C3 plants produce 3-phosphoglycerate and C4 plants produce Oxaloacetate.
c4 plants have first product of calvin cycle is oxaloacetic acid but in c3 plants is phospfoglyceric acid
The plants which live in water are aquatic plants.
In hot, arid conditions, C3 and C4 plants have to partially close their stomata to reduce water loss. However, this inhibits photosynthesis. Therefore, C3 and C4 plants are photosynthetically more efficient in more temperate environments.
Cam stands for Crassulacean acid metabolism. C3 and C4 conserve less water than Cam plants. Actually, C4 plant capture more carbon than C3 plant. In the struggle to reduce carbon dioxide concentration in the atmosphere, genetic scientists have modified some large scale crops into C4 bases. Cam plant is wholly different from C3 and C4 and examples of are the cactus and other succulent plants in order to survive in dry dusty regions. In Cam plants, [http://en.wikipedia.org/wiki/Carbon_fixation carbon fixation] occurs at night while C3 and C4 plants carry out photosynthesis during daylights.
By looking at their anatomy, in C3 plants, bundle sheath cells do not contain chloroplasts; carbon fixation and Calvin Cycle reactions occur in mesophyll cells (and in the presence of oxygen). In C4 plants, the bundle sheath cells contain chloroplasts; carbon is fixed in mesophyll cells, then transported to bundle sheath cells where Calvin Cycle reactions occur in the absence of oxygen. In both, photosynthesized sugars then enter the plant's vascular system. C4 have a concentric arrangement of the bundle sheath and mesophyll layer, the bundle sheath is also thicker. Another difference is their intervenial distances, from one bundle sheath to another you have in C4 only around 4 mesophyll cells but on 3 they are separated by 12. Overall, C4 plants are more adapted to environments with more oxygen, and C3 plants are more adapted to environments with more carbon dioxide.
C3
c3
Around 50ppm for C3 plants and around 5ppm for C4 plants.
c4 plants have first product of calvin cycle is oxaloacetic acid but in c3 plants is phospfoglyceric acid
Since C4 plants need for CO2 is more than C3 plants, doubling the concentration of CO2 will have more positive effect on C4 plants. If CO2 is a limiting factor for photosynthesis, both C3 & C4 plants will have positive effect.
The plants which live in water are aquatic plants.
yes more like c4 plants

c4
the question doesn't make sense
Yes it iz the c3 and c4
They are named after the number of carbons of the first product of their carbon fixation cycle (the cycle used to make plant sugars). C4 plants have a more elaborate carbon fixation cycle of C3 and reduces photorespiration. They are thought to have evolved more recently than C3 plants.
