Detailed explanation-1: -In plants with the C4 pathway either a single or a double layered sheath may be developed. In each case the parenchymatic cells are characteristically larger than the mesophyll cells. These bundle sheath cells are rich in organelles, with large and dark green chloroplasts that often show a reduced granai size.

Detailed explanation-2: -C4 plants have two types of photosynthetic cells: mesophyll and bundle sheath cells. Mesophyll chloroplasts are randomly distributed along cell walls, whereas bundle sheath chloroplasts are located close to the vascular tissues or mesophyll cells depending on the plant species.

Detailed explanation-3: -A layer of cells surrounding the vascular bundle, the bundle-sheath, is a common structural feature, but only in C4 plants does it contain chloroplasts. The bundle-sheath is thick-walled, sometimes suberized and there is no direct access from the intercellular spaces of the mesophyll.

Detailed explanation-4: -Summary – Mesophyll vs Bundle Sheath Cells In C4 plants, both mesophyll and bundle sheath cells are photosynthetic tissues. Mesophyll cells are present in the middle of the leaf surrounding the bundle sheath cells. The light-dependent reaction takes place in mesophyll cells in C4 plants.
