Transmission electron micrographs, transverse sections of cells within young hypophyses (stages 1–3). Cells contain abundant cytoplasm (c). (A) Stage 1: Plastid (p) with both starch granules (s) and poorly developed membranes. (B) Stage 1: Plastids with numerous starch granules; some appear to be dividing (arrows). (C) Stage 2: Plastids containing starch granules and/or further developed thylakoid membranes (t). (D) Stage 3: Plastids with starch granules of various sizes, and densely packed membranes. w: cell wall.
