All of the cells are in the very early stages of embryonic development and have not begun to differentiate into specialized types of cells. What type of cells would these be?

A) gametes
B) stem cells
C) somatic cells
D) epidermal cells

B) Stem cells

Gametes are haploid sex cells.
Somatic cells are eukaryotic cells that do not engage in sexual reproduction-these are your general body cells
Epidermal cells-These are basically skin cells.

stem cells

Stem Cells

The type of cells that are in the very early stages of embryonic development and have not yet differentiated into specialized types of cells are called stem cells.

To arrive at this answer, one can use their knowledge of cell differentiation and development, as well as the options provided. By eliminating other options, we can deduce that the correct answer would be stem cells.

Option A, gametes, refer to specialized reproductive cells like eggs and sperm, which are not relevant to early embryonic development.
Option C, somatic cells, are differentiated cells that make up the body tissues and organs after development.
Option D, epidermal cells, are a specific type of somatic cells that form the outermost layer of the skin.

Stem cells, on the other hand, are undifferentiated cells that have the potential to develop into various cell types. They are present in early embryos and have the ability to differentiate into any type of cell as the embryo develops. Hence, stem cells are the correct answer in this case.
