Reproductive cells are specialized cells that are responsible for the production of offspring. GAMETES, which are seven letters long, are reproductive cells that are involved in sexual reproduction and are haploid, meaning they contain half the number of chromosomes as a normal cell. OVA, which are three letters long, are female GAMETES, also known as eggs. Eggs, which are four letters long, are the female reproductive cells that are produced by the ovaries and are necessary for the production of offspring.
