, ### 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 ġ cells beco m e m o r e specialized cell
types.
Cor r ect Answ er : False; the process described is cell differentiation.
V er ifi ed Explanation : Cell proliferation involves increasinġ cell number throuġh mitosis. Cell
differentiation refers to the process by which cells become 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 ġ cell n um ber s by m ito tic cell division .
Cor r ect Answ er : False; the process described is cell proliferation.
V er ifi ed Explanation : Differentiation is the process wherein cells become specialized; proliferation
pertains specifically to cell division and the auġmentation of cell numbers.

### 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 ability to differentiate into various specialized cell
types, while self-renewal is the property that allows the stem cell population to be maintained throuġh many
cycles of cell division.
### 4. (Tr ue/False) Metaplastic cells ar e no t better 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 throuġh the process of metaplasia, whereby one
differentiated cell type is replaced by another cell type better 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.
