Question

Your body has a layer of skin that protects it from the environment. This layer of skin is made up of many individual skin cells. Explain where all the cells came from and how two individual cells share the same traits.

Answer 1

Stratum Corneum This layer is composed of the many dead skin cells that you shed into the environment—as a result, these cells are found in dust throughout your home. This layer helps to repel water.

Answer 2

The cells of the skin layer that protects the body came from preexisting cells.

This is according to the cell theory which states that:

1. cells are the basic unit of life
2. cells arose from existing cells by reproduction
3. all living organisms are made of cells

Cells can only arise from existing cells by a reproductive process known as cell division. Cells can divide by mitosis if they are vegetative cells or by meiosis if they are sex cells.

The daughter cells produced in meiosis are usually genetically and phenotypically different from their parent cells, unlike mitosis where the daughter cells are essentially the same as the parent cells both genotypically and phenotypically.

The cells of the skin are vegetative cells. Thus, they can only reproduce by mitosis. This is why individual skin cells share the same trait.
