It is important that a gamete or sex cells have exactly only one set of chromosome because during sexual reproduction two sex cells of the parents will form the zygote and it will have 2n or diploid number of chromosomes. It is from this zygote somatic cells are formed.

Simple epithelia have more layers for protection, whereas stratified epithelia allow materials to move across them and are less

xeze [42]

Answer: False.

Explanation:

Epithelial tissue is found in the linings of many structures throughout the body. There are two kinds of epithelial tissue: simple and stratified. And they perform different functions and are structured differently.

The simple epithelium consists of one single layer of cells. In this way, all cells are in direct contact with the basement membrane and are separated from the connective tissue. The main function of this epithelium is absorption and filtration.

The stratified epithelium is composed of many layers of cells that are stacked together. In this way, this epithelium has the function of protecting against physical and chemical damage.
