Dental Admissions Test (DAT) Practice Test

Progenitor cells in the skin are classified as unipotent. Unipotent cells are cells that have the ability to develop into only one specific type of cell. In the context of skin cells, progenitor cells are unipotent cells that can differentiate into a specific type of skin cell. Option A is incorrect because it lists the biological classification categories which are not relevant to the classification of progenitor cells in the skin. Option B (Ectoderm) is part of the three primary germ layers formed in the early stages of embryonic development and is not directly related to progenitor cells in the skin. Option C (Monera) is a biological kingdom mainly consisting of unicellular organisms like bacteria and archaea, which is not relevant to the classification of skin progenitor cells.
