Cells with 2 copies of each chromosome are called diploid, whereas cells with 1 copy of each chromosome are called haploid.

Explanation:

Cells which comprise of homologous pairs of chromosomes are known as haploid cells. For example, the autosomal cells in humans contain 23 pairs i.e 46 chromosomes in them.

Cells which have only one copy of the chromosome are termed as haploid cells. For example, the sex cells of the humans i.e egg cell and sperm cells comprise of 23 chromosomes. This is half the number of chromosomes than the autosomal cells.
