What is Photosynthesis?
ChemistryPhotosynthesis is the process of
converting light energy to chemical energy & storing it in the bonds of
sugar.
This process occurs in plants and some algae (kingdom protista). Plants
need only light energy, CO2 and H2O to make sugar. The
process of photosynthesis takes place in the chloroplast , Specially using
chlorophyll, the green pigment involved in photosynthesis.
Photosynthesis takes place primarily in plant leaves and little to none occurs in stems etc. The parts of a typical leaf include the upper & lower epidermins , themesophyll , The vascular bundle (S) (Veins) and the stronates. The upper & Lower epidermal cells do not have chromoplasts thus photosynthesis does not occur there they serve primarily as protection for the rest of the leaf.
The stomates are holes
which occur primarily in the lower epidermis and are for air exchange , they
let CO2 in and O2 out. The vascular bundles or veins in a
leaf are part of the plant's Transportation System , moving water &
Nutrients around the plant as needed. The mesophyll cells have chloroplast and
this is where photosynthesis occurs.
The overall chemical reaction involved in photosynthesis.
