Spiderwort lead surface. Light micrograph of a stomata (centre and bottom right) on the lead of a spiderwort (Tradescantia sp.) plant. Stomata are pores that are the site of gaseous exchange in the plant. The opening and closing of the stomata is controlled by semicircular guard cells. When the guard cells are turgid the stomata are open and when they are flaccid the stomata are closed | |
