How is a cam plant suited to its environment?

The CAM ( Crassulacean acid metabolism) plants live under arid / very dry environmental conditions. These plants have got specialized adaptation to survive under such conditions. They perform CAM photosynthesis that enable them to conserve water.

They close their stomata during day time and open them during night time to take in carbon dioxide. This prevents water loss during daytime in such plants.

The carbondioxide is stored in vacuoles in the form of four carbon compound called malate.

It is then utilized during day time ( as malate is released out of vacuoles and breaks down to give carbon dioxide that can enter calvin cycle) for performing photosynthesis.

the menstrual cycle – higher tier. negative feedback mechanisms affect the production of hormones in the menstrual cycle. oestrogen also stimulates the release of lh (luteinising hormone) from the pituitary gland, which in turn controls the production of progesterone.
