When the stomata in a leaf close then what?
This really REALLY depends on the plant species you’re referring to. But in general…(kind of) Some plants continue to produce sugar by anoxygenic (without oxygen) photosynthesis and various forms of anoxygenic glycolysis (sugar breakdown for energy). However, these anoxygenic processes can only go on for so long because of the build-up of toxic chemicals. You might want to read up on C4 plants, which have a special life cycle that places special significance on the time during which the stomata are closed. In addition, some plants begin to rid themselves of waste products and bring in nutrients, though this process is severely hindered in most plants because of the inability to transpire (you can look this up too) due to the closed stomata. These are just a few minor facts, but there’s a lot more to it, main thing to do is research.
