Noun
The word is derived from stoma
of Stoma
Source: Webster's dictionaryAt night, or when the plant is short of water, the stomata close and the CAM mechanism is used to store CO 2 produced by respiration for use later in photosynthesis. Source: Internet
In full CAM, the stomata open only at night, when temperatures and water loss are lowest. Source: Internet
This is an important role where water supply is not constant, and indeed stomata appear to have evolved before tracheids, being present in the non-vascular hornworts. Source: Internet
CAM-cycling is a less efficient system whereby stomata open in the day, just as in plants using the C 3 mechanism. Source: Internet
Early in their evolutionary history, the ancestors of modern cacti (other than one group of Pereskia species) developed stomata on their stems and began to delay developing bark. Source: Internet
Lack of phosphorus may interfere with the normal opening of the plant leaf stomata, resulting in plant temperatures 10 percent higher than normal. Source: Internet
