WebApr 22, 2014 · For example, the leak rate was estimated to be 11% of the CO 2 originally released in the bundle-sheath cells, but this value varied from 19 to 5% when the bundle-sheath resistance was halved or doubled (Furbank and Hatch, 1987). The method used by Hatch et al. is undoubtedly more direct and elegant but still requires a complex set-up. WebPericycle cells can divide and give rise to lateral roots in both monocots and dicots. Pith. Located in the middle of monocot roots, the pith (or medulla) is composed of soft, spongy parenchyma cells with spaces between them. The pith is surrounded by a ring of vascular bundles, containing xylem and phloem. See it in 3D! hubpensionconsulting.co.uk/bt

Bundle Sheath Cell - an overview ScienceDirect Topics

The 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. The Calvin cycle is confined to the chloroplasts of these bundle sheath cells in C4 plants. C2 plants also use a variation of this structure.
