WebOct 4, 2024 · C4 has one step in the pathway before the Calvin Cycle which reduces the amount of carbon that is lost in the overall process. The carbon dioxide that is taken in by the plant is moved to bundle sheath cells by the malic acid or aspartic acid molecules (at this point the molecules are called malate and aspartate). 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.
