The key difference between mesophyll and bundle sheath cells is that in C4 plants, light-dependent reactions of photosynthesis take place in the mesophyll cells, while light-independent reactions or Calvin cycle take place in the bundle sheath cells.. C4 plants are a group of plants that carry out C4 photosynthesis or C4 carbon fixation. Counted particles are those within the probe not intersecting the exclusion planes: point, counted particle; cross, particle is not counted. how would that change the amount of sunlight reaching the chloroplasts in the palisade layer? Each cell has a cellular space of 5 rows and a large intercellular space. What grade do you start looking at colleges? In these chloroplast-deficient sectors, palisade mesophyll cells are absent, producing a pale leaf with large air spaces composed largely of spongy mesophyll cells [36,37]. A tightly packed columnar cell matrix is found in palisade mesophyll, whereas a randomly stacked cluster of irregularly shaped cells is found in spongy mesophyll. Water, minerals, and other substances can be transported around the leaf as a result of this process. A cell from a leaf may contain from 20 to 100 chloroplasts (Figure 1). 2. Fewer chloroplasts in the spongy mesophyll because most of the light energy is absorbed by the chloroplasts of the palisade mesophyll. The cell walls of the mesophyll are usually thin and porous, allowing gases to diffuse freely in and out of the cell. The most photosynthesis occurs in the palisade parenchyma cells of the mesophyll.
