Question

C3 or C4 chair in defrent

Answer 1

In C3 plants, the bundle sheath cells do not contain chloroplasts. In C4 plants, the bundle sheath cells contain chloroplasts. In C3 plants, the carbon dioxide fixation takes place only at one place. In C4 plants, the carbon dioxide fixation takes places twice (one in mesophyll cells, second in bundle sheath cells).
