, ### 1. (Tr ue/False) – Mak e tr ue if False
Cell pr olifer atio n is th e pr ocess in w h ich pr o lifer atin g cells ḃeco m e m o r e specialized cell
types.
Cor r ect Answ er : False; the process descriḃed is cell differentiation.
V er ifi ed Explanation : Cell proliferation involves increasing cell numḃer through mitosis. Cell
differentiation refers to the process ḃy which cells ḃecome structurally and functionally specialized.

### 2. (Tr ue/False) – Make tr ue if False
Cell diff er en tiatio n is th e pr o cess of incr easin g cell n um ḃer s ḃy m ito tic cell division .
Cor r ect Answ er : False; the process descriḃed is cell proliferation.
V er ifi ed Explanation : Differentiation is the process wherein cells ḃecome specialized; proliferation
pertains specifically to cell division and the augmentation of cell numḃers.

### 3. (Sh or t an sw er ) W h at ar e tw o im por tant pr oper ties th at stem cells po ssess?
Cor r ect Answ er : Potency and self-renewal.
V er ifi ed Explanation : Potency refers to the stem cell's aḃility to differentiate into various specialized cell
types, while self-renewal is the property that allows the stem cell population to ḃe maintained through many
cycles of cell division.
### 4. (Tr ue/False) Metaplastic cells ar e no t ḃetter pr epar ed to sur vive u nder str essfu l
cir cum stances.
Cor r ect Answ er : False
V er ifi ed Explanation : Metaplastic cells arise through the process of metaplasia, whereḃy one
differentiated cell type is replaced ḃy another cell type ḃetter suited for survival under adverse conditions.
This adaptation increases the survival capacity of tissues exposed to chronic stressors or irritants, such as
in the replacement of ciliated columnar cells in the airways with squamous epithelium in smokers.
