Bundle sheath extension: A strip of ground tissue between vascular bundles and epidermis in leaf – can be hypodermal and consist of parenchyma, collenchyma or sclerenchyma. Can form girders … WebThe bundle-sheath cells are the photosynthetic cells arranged into a tightly packed sheath around the vein of a leaf. It forms a protective covering on leaf vein, and consist of one or more cell layers, usually parenchyma. Loosely arranged mesophyll cells lie between the bundle sheath and the leaf surface.

WebSolution Verified by Toppr Correct option is D) In C 4 plants, the bundle sheath cells have thicker walls and have no inter cellular spaces. These cells are not rich in PEP carboxylase. Bundle sheath cells have high density of chloroplasts compared to mesophyll cells. Thus, option D is correct and other options are incorrect WebPlastid number and morphology vary dramatically between cell types and at different developmental stages. Furthermore, in C4 plants such as maize, chloroplast ultrastructure and biochemical functions are specialized in mesophyll and bundle sheath cells, which differentiate acropetally from the proplastid form in the leaf base.
