Plants have two types of photosynthetic tissue, the palisade and the mesophyll, in addition to the palisade and mesophyll. The palisade mesophyll cells are arranged in columns, with the chloroplasts located near the top of the cell where they can receive the most light. Can We estimate the number of chloroplast cells in 3D? How does this aid key biological processes in plants? 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 importance of using a proper method for counting/sampling chloroplasts is obvious, because incorrect approaches can lead to serious bias in the chloroplast number estimation. Range 80 to 120 Chloroplasts/cell; Comments "Whereas wild-type plants have 80 to 120 chloroplasts per mesophyll cell, the accumulation and regulation of chloroplast (arc) mutants used in this study have between one and about 30 chloroplasts per mesophyll cell (Table III)." No, most chloroplasts are in the interior cells in leaves, termed the mesophyll, and the cells near the surface of green stems. How does the palisade and spongy mesophyll function in photosynthesis?
