Abstract: -(Histochemistry and ultrastructure of the ontogenesis of the tetrasporangia of Hypnea musciformis (Wulfen) J. V. Lamour. (Gigartinales, Rhodophyta)). Tetraspore development was studied in Hypnea musciformis (Wulfen) J. V. Lamour. using light and electron microscopes, and techniques of histochemistry. Tetrasporangial differentiation arises from a cortex cell that enlarges. This cell undergoes mitosis to form a tetrasporangial mother cell and a stalk cell. The histochemichal study indicated that the cell wall l…
