Description: Sperm cells are a part of the process necessary for eggs to develop into chickens in the first place. The acrosome is bounded by an acrosomal membrane and it contains certain acrosomal polysaccharides like galactose, mannose, fructose, and hexosmine Kopency, Exposure to hyperosmotic seawater also triggers the initiation of sperm motility of marine fish species[16, , ]. Pecio A, Rafinski J The spermatid stage is where the sperm develops the familiar tail.
