Question:

Distinguish sperm from eggs. In some primitive organisms, eggs and sperm are of similar size, and are motile. Discuss the application of the terms "male" and "female" in these cases and explain . How are the Gametes are of different sizes are called as?

Gametes:

Gametes, eggs and sperms, are haploid cells that are produced by female and male organisms. Upon fertilization, they fuse to form a diploid cell which then develops into a new offspring.

Answer and Explanation:

Sperm are distinguished from eggs in that they are motile, in all higher organisms. In primitive organisms, where eggs and sperm are of similar size and motile, the term "male" would refer to the gametes that have only one sex chromosome whereas "female" would refer to the gametes that have two sex chromosomes. When the gametes are of different sizes, the male gamete, sperm, is smaller than the female gamete, eggs.
