9. Give a comparison between the following:
(c) Anatomy of leaf in and plants
Anatomy of leaf in C3 plants | Anatomy of leaf in C4 plants |
Bundle sheath cells are absent | Bundle sheath cells are present around the vascular bundles |
RuBisCO is found in mesophyll cells | RuBisCO is found in bundle sheath cells |
Plants do not possess the 'Kranz' anatomy of leaves. |
Leaves show Kranz's anatomy |
Chloroplasts are of a single type only |
Chloroplasts are dimorphic. The chloroplasts of bundle sheath cells are larger and arranged centripetally. |
Mesophyll cells have intercellular spaces | Mesophyll cells do not have intercellular spaces |
