The primary difference between C4 and CAM plants transfer the CO2 molecules to lessen photorespiration while CAM plants choose when to extract CO2 from the environment. The C4 plants avoid moving the CO2 molecules into the bundles where CO2 concentration is substantially much higher than oxygen.

CAM (Crassulacean Acid Metabolism) plants have a very different but more successful approach to conserving water. They collect CO2 at night when it is much more relaxed, and the stores are the concentrated CO2 as malate. This collection is often released back when it is daytime, and water evaporation is more likely because of the heat.

C4 plants are typically summer plants such as corn and sugar cane. They can endure high temperatures and reduced water supply to some extent. On the other hand, CAM plants are more appropriate in dry environments.

It can be confusing for some people to know the difference between C4 and CAM plants. When you say C4, these are the plants that are meant to promote the operation of the Calvin-Benson Cycle. C4 plants will normally minimize photorespiration.

It can be confusing for some people to know the difference between C4 and CAM plants. When you say
CAM cells, on the other hand, will fix carbon at night and will also make sure that the OAA will be placed in large vacuoles within the cell. Remember that fixing carbon is one of the things that plants can do so that carbon can be transformed into more organic molecules, which means that they can turn into oxygen, which other living things may need.
