Basic Types of Taxonomic Characters Comparison of material depends to some extent on the purposes of the comparison. For mere identification, a suitable key, with attention given only to the characters in it, may be enough in well-known groups. If the form is likely to be a new one, its general position is determined by […]

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.
