Cells starting mitosis and meiosis begin with what set of chromosomes. True or False
Arisa [49]

Answer:

with haploid or diploid set of chromosomes. True

Explanation:

There are two types of cells in the body, haploid cells and diploid cells. The biggest difference is related to the number of chromosomes that each cell contains, while diploid cells contain two chromosomes (2n), haploid cells contain a chromosome (1n).

Features:

1. A haploid cell has only one set of chromosomes (n), while diploid cells have two sets of chromosomes (2n).

2. In humans, somatic cells are diploid, while gametes are haploid.

3. Diploid cells develop as a result of mitotic cell division, while haploid cells develop as a result of meiotic cell division.

4. Mitosis produces 2 identical daughter cells, where both stem and daughter cells are diploid. In meiosis, a diploid cell divides twice to produce 4 haploid daughter cells.

5. Humans and most animals are considered diploid organisms, while algae and fungi are examples of organisms that are haploid in most of their lives. Male bees, wasps and ants are also haploid.
