The correct answer is: gametes.

What the question is asking

The question “which consist of sperm cells and egg cells? gametes tetrads diploids chromosomes” is asking which biological term refers to the group or type that includes sperm and egg cells.

  • Sperm and egg cells are sex cells used in sexual reproduction.
  • The biological term for sex cells (sperm and eggs) is gametes.

Why the other options are wrong

  • Tetrads : These are structures of four chromatids formed when homologous chromosomes pair during meiosis I, not whole sex cells.
  • Diploids : This describes cells with two full sets of chromosomes (like typical body cells or a zygote), not specifically sperm or egg cells.
  • Chromosomes : These are DNA-containing structures inside cells, not the cells themselves. Sperm and eggs each contain chromosomes, but they are not “made of” sperm and eggs.

Quick scoop: key idea

  • Sperm + egg cells = gametes (sex cells, haploid).
  • When gametes fuse, they form a diploid zygote.

So, among “gametes, tetrads, diploids, chromosomes,” the group that consists of sperm cells and egg cells is gametes.
