photosinthasis is how plants make their own food by sunlight. how photosinthasis works is simply using sunlight,co2,water and nutrition to make glucose for biomas(to grow).

well now we will talk about the leaf which has a lot of features like… the stomata is mostly at the bottom of the leaf to inhale and exhale.

 

Inhale      Exhale

Co2       Oxygen

so they breath what we exhale and we breath what they exhale.

Also in the leaf there is the xylem and Phloem which do the following…

xylem=to transfer food around the leaf

phloem=To transfer water around the body

Back to the plant it self the equation to photosinthasis is…

 

Co2+water>sunlight&oxygen gluecos+oxygen

Also at the very top of the plant there is the chloroplast and the chlorophyll to absorb all the sunlight it can get just like solar panels so they will go to no use if they were at the bottom.
