Let's break down the terms:

Haploid: A haploid cell refers to a cell that contains a single set of chromosomes. In humans, haploid cells are the sex cells or gametes, such as sperm cells in males and egg cells in females. Haploid cells have half the number of chromosomes compared to the somatic cells in the organism.

Diploid: A diploid cell refers to a cell that contains two sets of chromosomes. In humans, diploid cells are the somatic cells, which make up the majority of the body's cells. Each somatic cell contains two copies of each chromosome, one inherited from each parent.

So, in summary, the correct answer (A. haploid; diploid) indicates that a haploid cell has only one set of chromosomes, while a diploid cell has two sets of chromosomes.

Answer:

A. haploid; diploid

Step-by-step explanation:

Gametes are haploid cells, which means they contain only one set of chromosomes. Diploid cells, on the other hand, contain two sets of chromosomes.

So the answer is A.

Here is an explanation:

  • Haploid cells have a single set of chromosomes, meaning they only have one copy of each chromosome. This is the case for gametes, which are the sex cells that fuse together to form a zygote.
  • Diploid cells have two sets of chromosomes, meaning they have two copies of each chromosome. This is the case for most cells in the body, including somatic cells and stem cells.

So, when a sperm cell and an egg cell fuse, they each contribute one set of chromosomes to the zygote, which is why the zygote is diploid.
