Bundle-sheath Cells
Bundle-sheath cells are photosynthetic cells arranged into tightly packed sheaths around the veins of a leaf. They form a protective covering on leaf veins, 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.

“If I’d written all the truth I knew for the past ten years, about 600 people—including me—would be rotting in prison cells from Rio to Seattle today. Absolute truth is a very rare and dangerous commodity in the context of professional journalism.”
—Hunter S. Thompson (b. 1939)
