They capture the Electrical power in daylight and utilize it to produce very simple sugars, including glucose and sucrose, from carbon dioxide and water.

Their surfaces are waterproofed through the plant cuticle and fuel Trade among the mesophyll cells plus the environment is controlled by minute (length and width calculated in tens of μm) openings termed stomata which open or close to regulate the rate Trade of carbon dioxide(CO2), oxygen(O2) and drinking What everyone is talking about water vapor into and away from The interior intercellular space technique.
