this presentation is made when my teacher asks me to make a presentation of what I learned in proper use of presentation....

2. Photosynthesis
 is the process by which plants, some bacteria,
and some protistans use the energy from
sunlight to produce sugar, which cellular
respiration converts into ATP, the "fuel" used by
all living things.
 The conversion of unusable sunlight energy
into usable chemical energy, is associated with
the actions of the green pigment chlorophyll.

3. Overall reaction of this process as:
“six molecules of water plus six molecules
of carbon dioxide produce one molecule of
sugar plus six molecules of oxygen”

4. Two Parts of
Photosynthesismembrane
Light Reaction
---happens in the thylakoid
and converts light energy to chemical
energy.
Dark reaction
---takes place in the stroma within the
chloroplast, and converts CO2 to sugar.

6. Dark Reaction
Dark reaction or Calvin cycle can be
represented as follows
3 CO2 + 9 ATP + 6 NADPH -->
glyceraldehyde-3-phosphte + 9 ADP + 8 Pi
