The process in which two gametes fuse to make one cell is called

Gametes are haploid cells that fuses with another haploid cell during fertilization. For human being, the gametes are the egg cells and the sperm cells and human fertilization is the union of a human egg and sperm, which usually occur in the ampulla of the fallopian tube.

A gamete is a male or female sex cell. For example, in animals a male gamete is known as a sperm cell and a female gamete is known as an egg or ovum. The fusion of two gametes allows the production of a new living organism and this process is known as fertilisation.

answer: - b cells

explanation: -

there are many types of white blood cells present in our body. one such class of white blood cells are the lymphocytes. the b cells belong to the lymphocyte class of wbcs. the b cells perform their action against the pathogen by producing specialised proteins called as antibodies. these antibodies are produced as and when the b cells encounter pathogens in response to the antigens present on the surface of the pathogen. these antibodies bind to the antigens present on the pathogen and then, target them for destruction by other cells of the immune system.

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.
