Schematic o photosynthesis in plants. The carbohydrates produced are stored in or uised bi the plant.

Photosynthesis is a process uised bi plants an ither organisms tae convert licht energy, normally frae the sun, intae chemical energy that can be uised tae fuel the organisms' activities. Carbohydrates, such as succars, are synthesized frae carbon dioxide an watter (hence the name photosynthesis, frae the Greek φῶς, phōs, "licht", an σύνθεσις, synthesis, "puttin together"[1][2][3]). Oxygen is an aa released, maistly as a waste product. Maist plants, maist algae, an cyanobacteria perform the process o photosynthesis, an are cried photoautotrophs. Photosynthesis maintains atmospheric oxygen levels an supplies aw o the organic compoonds an maist o the energy necessary for ae life on Yird.[4]
