Maverick: What part of a leaf or plant changes CO2 into O2, and how?

Question

To Maverick, who answered my last question about a stage in photosenthesis. I just want to know what part and how a plant can take the carbon dioxide in the air and transform it into pure oxygen.

PS: Don't listen to all of those guys who say you can't be all of those -ologists at once. A few of those guys don't even know what cytoplasm is...

Answer 1

Mesophyll

EDIT:

For Mesophyll, there are palisade (vertical, tight columns near the upper leaf surface) and spongy (rounder cells with air spaces between them to allow CO2 to diffuse from the stomata through the leaf) mesophyll cells.

Answer 2

Sorry but plants do not change CO2 into O2.Please take time to read my reply - the answers you want are here.

CO2 is fixed in the dark stage of photosynthesis (Calvin Cycle) in the stroma of chloroplasts. This occurs mainly in the palisade mesophyll cells of leaves and the CO2 reaches these cells by diffusing through the stomata in the epidermis of the leaves.

Oxygen is produced in separate reactions of the light stage of photosynthesis, again in the chloroplasts but in the thylakoid membranes and is derived from the splitting of water (photolysis) which reaches the leaves via the xylem.
