Identify the strategies that CAM (crassulacean acid metabolism) plants use to minimize water loss while obtaining CO2 (carbon dioxide) for photosynthesis.

Explanation:

crassulacean acid metabolism (CAM) plants minimizes loss through separation in time. The stomata of CAM plant is opened at the night and carbon dioxide is trapped in and then closed in the morning to minimize water Loss.

The carbondioxide that is trapped in is ferried via phosphoenol pyruvate (PEP) and then broken down by PEP carboxylase to form oxaloacetate from there it is further broken down to malate or malic acid and other organic acid. It is therefore stored in the vacoule as malic acid until when it is needed in the day where it will be broken down into pyruvate and Carbondioxide.

Loss is minimize by through the closure of stomata during the day this is to prevent excessive transpiration when the weather is hot and stomata is opened.
