C4 and CAM plants have adapted to living in environments where water loss is a problem. C4 plants fix carbon dioxide , whereas CAM plants fix carbon at .

1. Different locations .

2. Different times of the day

Explanation:

Both C4 plants and the CAM plants are highly adapted to survive in the arid or dry conditions. In arid conditions, the high temperature is measured which could interfere with the metabolism of the plants.

So plants have adapted in various forms like the C4 plant to avoid high temperature by performing the process of photosynthesis in different cells especially the mesophyll cells and the bundle sheath cells.

The CAM plants avoid high temperature by closing stomata during daytime and performing photosynthesis at night time.
