part_of physiological process of malaria vector ultrastructural changes in the Trophocytes previtellogenic development During the first three days after emergence the nucleolus grew >3-fold and its enlarging granular component came to contain many maturing pre-ribosomes. The number of ribosomes in the cytoplasm increased sharply. Rough endoplasmic reticulum appeared in the form of cisternae,located in rows, Conentric circles or round lipid inclusions. The Golgi complexes developed into well-defined organelles consisting of small vesicles, 3-4 short vesicular cisternae, and a few larger vesicles. The plasma membrane bacame extended into numerous infoldings, increasing its surface area. IDOMAL:0002378 IDOMAL:0002378 In newly emerged females the cytoplasm of each trophocyte was rich in reserves, containing lipid droplets, glycogen bodies, and three types of membrane-bounded protein granule. idomal_namespace previtellogenic development During the first three days after emergence the nucleolus grew >3-fold and its enlarging granular component came to contain many maturing pre-ribosomes.
