Transmission electron micrographs of W. globosa fronds. A-B, Lens-shaped chloroplasts (CH) containing starch grains (SG) distributed in mature mesophyll cells and their magnification, CM- cell membrane. C, The photosynthetic membrane system of CH containing a granum (GR) composed of thylakoids. D, Cell of meristematic area showing larger nuclei (NU) and smaller vacuoles (VA). E, The CH in meristematic area. FG, Cell of daughter frond showing more mitochondria (MI). H, Cell of reproductive pocket was highly vacuolated (VC, vacuolated cells). I, Transfer cells (TC) in most adjacent mature mesophyll cell. Bars = 1 μm
