Photosynthesis is the conversion of light energy into chemical energy by green plants and other
organisms.
6H2O + 6CO2 = C6H12O6 + 6O2
The above means water + carbon dioxide gives glucose plus oxygen.
Photosynthesis takes place in the chloroplast. Chloroplast use solar energy to manufacture
ATP, fix CO2 in the atmosphere into sugars, and produce oxygen. Here is what a chloroplast
looks like:
(,1.)
The first thing you can see in the stroma. Chloroplasts are spilled in a protein-rich fluid( this
is the stroma). Next there is the inner membrane which controls the materials flow into and
out of the chloroplast. The thylakoid is the place of the light-dependent process that takes
place on a sheet-like membrane. It has chlorophyll, absorbs light, and produces ATP. The
granum increases the surface area of the thylakoid, allowing more light to pass through to
the chlorophyll. The outer membrane serves as a solute permeability membrane barrier,
allowing specific materials to enter and leave the cell. And finally the lamellas connect two
