Areas with high daytime temps, high sunlight, and droughts, so sand desserts and some others.
The plants which live in water are aquatic plants.
Products such as G3P or PGAL are produced in the Calvin cycle in C3, C4, and CAM plants. Carbon fixation helps each plant adapt to the particular environment they live in. C4 plants are those such as sugarcane or grasses. CAM plants are the cactus plants or plants that live in the desert. It also helps with the production of ATP.
Well, broccoli is a c4 plant because plants that are in the section of c3 live in hot, dry temperatures and climates. So cacti would be a great example of c3 plants. Broccoli is not a c3 plant it is a c4 plant. So a way to remember this would be to say that warm or cool plants with rainy season and those whom actually get water more then once in every blue moon are c4 plants and then those whom get water few times a year and live in desert type climates are c3 plant. Hope this helped you, if you have anymore questions you may email me at dmac558@aol.com.
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.
Here is a partial list of C4 plants. http://www.bio.net/bionet/mm/ecophys/attachments/20071014/7a9bede1/C4plantslistfromPhotosynthetica1992-0001.pdf
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.
C3 due to the abundance of water. C4 and CAM plants tend to inhabit very dry environments and have adaptations that minimise photorespiration (a process that wastes ATP) and water loss.
Around 50ppm for C3 plants and around 5ppm for C4 plants.
C4 plants that use the C4 pathway require more ATP and NADPH
The C4 plants tend to keep their stomata closed during the day to conserve water.

C4 plants have concentric rings of mesophyll cells around vascular bundle sheath in the leaves.
