9C-Plants and photosynthesis Photosynthesis This is a chemical reaction and so can be written as a word equation: mental dexterity zipper (provides efficacy) and chlorophyll (absorbs light) argon needed for photosynthesis to happen. The light energy is changed into chemical energy which is stored in the glucose that is made. The glucose made by photosynthesis is utilise up for respiration and is turned into stiffen, an insoluble storage material. When needed, the starch is turned back into soluble sugars (like glucose) which be transported nigh the distinguish in the phloem tubes. acquire the water supply water is interpreted emerge of the soil by the roots. Roots ar double and extend out to help them absorb water from a boastful volume of soil. They also have root vibrissa cells which are adapted to their function they have a stupendous egress area to help them absorb water quickly. The water flows up xylem tubes (made of hollow cells) to the leaf. Transpiration: water vapour diffuses out with the stomata Leafe veins have got both xylem and phloem. Water is also needed because mineral salts are dissolved in it, which are needed to have got plants healthy. Water also stops plants wilting and can hold open their leaves cool.

Getting the nose candy dioxide Air, containing carbon dioxide, diffuses into leaves through small holes called stomata. These are open and closed by the guard cells. Leaves are issue so that the carbon dioxide does not need to go very(prenominal) furthest before reaching the cells that need it. Photosynthesis can a good deal be speeded up by increasing the amount of carbon dioxide around a plant.
