Final answer:
The female cells are called egg, and the male cells are called sperm. These cells join together to form a zygote.
Step-by-step explanation:
Gametes are specialized reproductive cells that are essential for sexual reproduction in sexually reproducing organisms. These cells, produced through a process called gametogenesis, are responsible for transmitting genetic material from one generation to the next. Gametes are haploid, meaning they contain half the number of chromosomes compared to the somatic cells of the organism.
The female cells called an egg, and a male cell, called a sperm, join to form a zygote.
