WebApr 11, 2024 · Bundle sheath cells are a type of photosynthetic cells that occur covering the vascular bundle of C4 plants. The main significant feature of the bundle sheath cells is the presence of chloroplasts close to the vascular cells. However, the chloroplasts of the bundle sheath cells are fewer. In the meanwhile, they contain fewer or no grana. WebFurther it has enzyme PEP-carboxylase. 1 RUBP-carboxylase is absent in mesophyll chloroplasts but is present in bundle sheath chloroplasts. The first product formed is oxaloacetic acid and this is because it is known as C 4 cycle. Bundle sheath cells fix CO 2, through C 3 cycle.
WebMar 18, 2024 · PEP fixes carbon dioxide into a four-carbon molecule, called malate, that is transported to the deeper bundle sheath cells that contain Rubisco. The malate is then broken down into a compound that is recycled back into PEP and carbon dioxide that Rubisco fixes into sugars—without having to deal with the oxygen molecules that are …
