Explain photosynthesis

photosynthesis is how plants manufacturer their own food but do you know how they do it.How they do it is when the roots xylem sucks in the minerals the minerals will go up the stem.Then it will go in the leaves but the leaves take in CO2 and take out O2 so  when it take in CO2 it will use the minerals and the sunlight does are the things that it needs inside the leaves they have chlorophyll. Chlorophyll are the stuff that make the plants glucose, glucose are the plants food but if there is no sun the chlorophyll can't make food that why you in winter they have no leaves but autumn tells them to get ready for winter so when winter comes they go to sleep but if it summer they make their food. So when the leaves finish making its food it will go up a straw called phloem when it goes up the phloem and to the rest of the part of the plants
