Final answer:
A haploid cell contains one set of chromosomes, while a diploid cell contains two sets of chromosomes
Step-by-step explanation:
In biology, the term 'n' refers to the number of chromosomes. A haploid cell contains one set of chromosomes, represented as 1n, while a diploid cell contains two sets of chromosomes, represented as 2n. For example, human body cells are diploid with 46 chromosomes (2n), while human gametes such as sperm and eggs are haploid with 23 chromosomes (1n).
