Sperms are male reproductive cells. Each sperm cell consists of a haploid nucleus, a propulsion system to move the nucleus, and a sac of enzymes that enable the nucleus to enter the egg. In most species, almost all of the cell’s cytoplasm is eliminated during sperm maturation, leaving only certain organelles that are modified for […]

Acrosome reaction assists in fusion of plasma membrane of egg/ovum and sperm. Interaction between sperm and egg jelly results in the acrosome reaction. In most marine invertebrates, the acrosome reaction has two components. 1- The fusion of the acrosomal vesicles with the sperm cell membrane. 2- The extension of the acrosomal process. Acrosome Reaction in

Fertilization is the process whereby the sperm and the egg—collectively called the gametes—fuse together to begin the creation of a new individual whose genome is derived from both parents. Fertilization accomplishes two separate ends: sex (the combining of genes derived from two parents) and reproduction (the generation of a new organism). Thus, the first function

Developmental Biology studies the initiation and construction of organisms rather than their maintenance.It is a science of becoming, a science of process. Formation of orderly body from a single cell by passing through various stages is called Development. That formation takes place according to the instructions which are encoded in genes and transmitted from parents.
