Question

What is the fusion of male and female gametes that are termed as?

Answer 1

Hint: Reproduction is an important process that must take place in all the living organisms to produce its offspring. It takes place sexually and asexually. Sexual reproduction mainly takes place in multicellular organism where the asexual reproduction takes place in the unicellular organisms like amoeba etc. or it detach from the multicellular organism.

Complete answer: or Complete step by step answer:
In human beings, the reproduction takes place internally by the fusion of the female egg and the male sperm. By which the female egg gets fertilized to produce the new young ones. This process of fusion of male and female gametes is called fertilization. This fertilization process takes place internally in the fallopian tube of the female and transforms into the zygote which developed into the new baby. The fertilization takes place in four process
(1) Sperm preparation
(2) Sperm egg recognition and binding
(3) Sperm egg fusion
(4) Activation of zygote

Thus, fertilization is the correct answer.

Additional Information:
Reproduction may also take place asexually by budding, binary fission, fragmentation, spore formation, not involved in the fusion of gametes. Some of the multicellular organism also undergo asexual reproduction. Example for this reproduction is earthworm.

Note:
Sexual Reproduction takes place in three stages. Pre-fertilization, fertilization and post-fertilization. Pre-fertilization takes place prior to the fertilization, fertilizer deals with the fusion of male and female gamete and post-fertilization deals with formation of zygote and new young ones.
