Biology Chapter 8: Reproduction and Development

Question 1

Multipotency

Answer 1

describes progenitor cells which have the gene activation potential to differentiate into multiple, but limited cell types. For example, a multipotent blood stem cell is a hematopoietic cell, and this cell type can differentiate itself into several types of blood cells, such as lymphocytes, monocytes, and neutrophils, but cannot differentiate into cells of other lineages.

Question 2

pluripotent

Answer 2

stem cell can give rise to cells of any of the three germ layers: endoderm (tissue lining the gastrointestinal and respiratory linings), mesoderm (muscle, bone, blood, and the lining of most of the urogenital system), or ectoderm (epidermal and nervous tissues).

Question 3

Totipotency

Answer 3

is the ability of a single cell to divide and produce all of the differentiated cells in an organism (e.g., a zygote is a totipotent cell)
