A leafs photosynthesis is made up of a thin layer of long, thin cells that are oriented in a perpendicular direction to the leafs surface. Chloroplasts are organelles that contain the pigment chlorophyll, which is necessary for photosynthesis. On the leaf, sponges are surrounded by many air spaces. 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]. For example, the number of chloroplasts per unit of leaf area was estimated from the number of chloroplast profiles in a 0.8 m thick section observed by light microscopy (Miyazawa and Terashima, 2001; Oguchi et al., 2005) and the number of mesophyll cells per leaf area was determined from the number of cell profiles in 5 m thick sections (Adachi et al., 2013). The hypostomatous species, which was excluded from the regression, and the amphistomats species, which was excluded from the regression, are represented by open circles and open triangles. They are a type of ground tissue that is actually found as two distinct types in the leaves. The chloroplasts contain the pigment chlorophyll. Chloroplasts labelled by crosses are not counted by any of the three probes shown here, but they would be unambiguously sampled by adjacent hypothetical probes. The difference between both estimators tested can be seen in the palisade mesophyll consists of with! A chloroplast, which is an organelle that helps to photosynthesis, is also produced by mesophyll cells. This can also improve the size of the leaf, allowing for a larger amount of sunlight to be captured for photosynthesis. 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. Dean
