2
Q
What is the equation of photosynthesis?
A
6CO2 + 6H2O —> C6H12O6 + 6O2
3
Q
Where does photosynthesis take place in eukaryotes?
A
In the chloroplast
4
Q
How did the chloroplast evolve?
A
Through endosymbiotic bacterium. it was engulfed by another cell.
5
Q
What is the evidence of endosymbiotic bacterium evolution?
A
The chloroplast contains:
- 2 layers of phospholipids
- 70s ribosomes
- circular, naked DNA
6
Q
Discribe the membrane of the chloroplast.
A
It has 2 outer membrane layers.
