WebChloroplast in the bundle sheath cells is centrifugally arranged with the presence of large starch granules and unstacked thylakoid membranes. The thylakoid membrane helps to absorb sunlight during the process of photosynthesis. There is presence of bundle sheath cells that are surrounded by one or more layer of mesophyll cells. WebBundle sheath definition, a layer of cells in plant leaves and stems that surrounds a vascular bundle. See more.
WebMay 1, 1999 · Consequently, bundle sheath chloroplasts swell, and internal thylakoid membranes break down in the light. Interestingly, mesophyll cell chloroplasts remain intact (Roth et al., 1996). In this study, we used the transposon-induced allele bsd2-m1 to clone the Bsd2 gene. We show that the gene product has features of a cysteine-rich Zn binding ... WebBundle sheath chloroplasts have been isolated from Zea mays leaves by a procedure involving enzymic digestion of mechanically prepared strands of bundle sheath cells followed by gentle breakage and filtration. The resulting crude chloroplast preparation was enriched by Percoll density layer centrifugation to yield intact chloroplasts (about 20 ...
