Science Aspect : Photosynthesis

Bio Aspect : Photosynthesis

It happens in plant cell which have chloroplast,not just in the leaf.
Light reaction happens in granum(make H+,ATP,NAPDH, and oxygen),and the dark reaction happens in stroma(make starch).
Info :
1. Experiment by Engellmann use algae(Spyrogyra) and bacteria.The movement bacteria to the algae called phototaxis...
2. Chloroplast consist of granum(is round part of chloroplast) and stroma(space in chloroplast).And has 2 membrane.
3. Especially happens in leaf tissue,is in palisade and spongy mesophyll tissue.
4. Just in cyanophyta(kind of monera kingdom),algae(kind of protist kingdom), and plant cell that have chloroplast.

Chemical Aspect : Photosynthesis 
Make starch (C6H12O6) and oxygen(O2) from water(H2O) and carbon dioxide (CO2) with light and chlorophyll in chloroplast.
Reaction :  H2O + CO2 + light + chlorophyll
Info : 
1.Chlorophyll consist of 2 :
Chlorophyll a (C55H12O5N4Mg) and Chlorophyll b (C55H10O6N4Mg)
2.C6H12O6 has empyric formula of (CH2O)n.
Empyric formula is formula that indicated minimum formula of a compound.
Example : Empyric formula of H2O2(hydrogen peroxide) is (HO)n
n indicated how much atom molecule of compound
3. Experiment : Sachs : Carbon(C : has atomic number 6) paper and alcohol (C2H5OH)
4.  Experiment : Ingenhouzh : Make oxygen(O2) has atomic number of 8
