WebDec 24, 2024 · The Calvin Cycle In plants, carbon dioxide (CO 2) enters the leaves through stomata, where it diffuses over short distances through intercellular spaces until it reaches the mesophyll cells. Once in the mesophyll cells, CO 2 diffuses into the stroma of the chloroplast, the site of light-independent reactions of photosynthesis. WebThe C 4 pathway acts as a mechanism to build up high concentrations of carbon dioxide in the chloroplasts of the bundle sheath cells. The resulting higher level of internal carbon …
