what is photo synthesis
Answers
Answer:
Photosynthesis is the process by which plants and some microorganisms make substances like carbohydrates.[1] It is an endothermic (takes in heat) chemical process that uses sunlight to turn carbon dioxide into sugars. The sugars are used by the cell as energy, and to build other kinds of molecules.
Photosynthesis is very important for life on Earth. Green plants build themselves using photosynthesis. Algae, protists and some bacteria also use it. Some exceptions are organisms that directly get their energy from chemical reactions; these organisms are called chemoautotrophs.
Photosynthesis can happen in different ways, but there are some parts that are common.
6 CO2(g) + 6 H2O + photons → C6H12O6(aq) + 6 O2(g)
carbon dioxide + water + light energy → glucose + oxygen
The carbon dioxide enters the leaf through the stomata by Diffusion from the atmosphere.
The water is absorbed from the soil by root hair cells, which have an increased surface area for an increased uptake of water.
Photosynthesis occurs in the chloroplasts in leaves (or other green tissues). They contain chlorophyll, the green pigment that absorbs light energy. In leaves, palisade cells have chloroplasts to capture light.
Oxygen is a waste product of photosynthesis: it comes out of the plant in respiration. All the oxygen in the atmosphere has its origin in plants (including those microorganisms which do photosynthesis)
Glucose is used in respiration (to release energy in cells). It is stored in the form of starch (which is converted back to glucose for respiration in the dark). Glucose can also be converted into other compounds for growth and reproduction e.g. cellulose, nectar, fructose, amino acids an
