Definition
  1. Noun:
    • A specialized cell involved in sexual reproduction: A reproductive cell is a biological cell that fuses with another reproductive cell during fertilization to form a new organism. It is responsible for transmitting genetic material (DNA) from one generation to the next.
    • Synonymous with gamete: The term is a general, formal synonym for a gamete, which can be either a male sperm cell (spermatozoon) or a female egg cell (ovum).
Usage Examples
  • Noun:
    • The fusion of two reproductive cells, one from each parent, creates a zygote.
    • In humans, the male reproductive cell is called a spermatozoon, and the female reproductive cell is called an ovum.
    • The primary function of a reproductive cell is to carry half the genetic information needed to form a new individual.
Advanced Usage
  • In developmental biology: The term is used to discuss the origin and maturation of these cells, often in the phrase "reproductive cell line" or "germ cell line," which gives rise to gametes.
    • Mutations in the reproductive cell line can be passed on to offspring.
  • In contrast to somatic cells: Reproductive cells (gametes) are haploid and involved in heredity, whereas somatic cells are diploid and make up the body's tissues.
    • Unlike somatic cells, reproductive cells undergo meiosis to reduce their chromosome number by half.
Variants and Related Words
  • Gamete (n): The direct synonym for a reproductive cell.
  • Germ cell (n): A cell that gives rise to gametes; a precursor to a reproductive cell.
  • Spermatozoon / Sperm (n): The male reproductive cell.
  • Ovum / Egg cell (n): The female reproductive cell.
  • Zygote (n): The cell formed by the union of two reproductive cells.
Synonyms
  • Gamete: The most precise and common synonym.
  • Sex cell: A less formal, descriptive synonym.
Related Phrases and Terms
  • Reproductive system: The organs and structures involved in producing reproductive cells.
  • Fertilization: The process in which two reproductive cells fuse.
  • Haploid cell: A cell with a single set of chromosomes, like a reproductive cell.
Noun
  1. a spermatozoon or an ovum; a cell responsible for transmitting DNA to the next generation
