pore connect the internal atmosphere of the leaf with the surrounding,cells guard contain chloroplast,the walls of the guard cells enclosed the pore are strengthrnedby cellulose microfibrils,no gas exchange happen during night as stomata close,loss of turgidity in guard cells when stomata being open

Carbon dioxide is diffused into the leaves during stomata opening.

Water and oxygen are diffused out of the leaves during stomata closing.

•each pore is surrounded by a pair of guard cells
•guard cells can change shape to open or close the stoma]]> 2022-03-31 04:42:23 UTC https://padlet.com/g44398717/ho1ik195vau6nzen/wish/2122836419 https://padlet.com/g44398717/ho1ik195vau6nzen/wish/2122836738 What is a stoma?

A stoma which is a singular form of stomata is a plant cell structure in the epidermis of tree leaves and needles that help plants exchange carbon dioxide and water with the atmosphere.]]> 2022-03-31 04:42:39 UTC https://padlet.com/g44398717/ho1ik195vau6nzen/wish/2122836738 https://padlet.com/g44398717/ho1ik195vau6nzen/wish/2122841083 no gas exchange happen during night as stomata close
