(a) Guard cells;
(b) Cells walls are thicker on the inner side then the outer side; which enables them to pull inwards when the cells are turgid; contains chloroplasts that are able to phosynthesize and produce sugars which enable them to absorb water
(c) Accumulation of carbon (IV) oxide in the leaf forms a weak carbonic acid; lowering the pH which favours conversion of sugar to starch; causing the guard wells to lose turgidity; and close;
