1.
  • the process wherein “general” or “common” cells evolve to form specific cells that have specific functions.

a)

un-specialized

b)

Cell modification

c)

mutations

d)

cell specialization

2.

HOW DOES A CELL BECOME SPECIALIZED?

a)

During transcription, the DNA becomes prone to mutations and the process of cell specialization makes it less susceptible to them, hence preventing further damage in the gene


b)
  • multiple stages of development. During cell specialization, the cell size and shape changes dramatically, as does its ability to respond to signaling molecules.

c)

One of the most overlooked significance of cell specialization is its importance in the production of cells that can produce signals that influence the activities of their neighboring cells. As a result, these cells collectively react toward a specific stimulus.

d)

 these stem cells can remain “un-specialized” until they need to.

3.

the DNA becomes prone to mutations and the process of cell specialization makes it less susceptible to them, hence preventing further damage in the gene

a)

REPLACEMENT OF OLD AND WORN-OUT CELLS

b)

POSSIBLE MEDICAL IMPORTANCE

c)
  1. IMPORTANCE IN CELL-TO -CELL COMMUNICATION 

d)

PRESERVE THE GENETIC MATERIAL

4.

The division of these stem cells into specialized cells is often triggered by certain environmental conditions. For instance, these new cells from the stem cells will then be used to replace any old or worn-out cells, hence maintaining their integrity as tissues or organs. 


a)

PRESERVE THE GENETIC MATERIAL

b)
  1. REPLACEMENT OF OLD AND WORN-OUT CELLS

c)
  1. IMPORTANCE IN CELL-TO -CELL COMMUNICATION 

d)

POSSIBLE MEDICAL IMPORTANCE

5.

treating certain diseases like diabetes and cardiovascular ailments.


a)

POSSIBLE MEDICAL IMPORTANCE

b)

IMPORTANCE IN CELL-TO -CELL COMMUNICATION

c)

PRESERVE THE GENETIC MATERIAL

d)
  1. REPLACEMENT OF OLD AND WORN-OUT CELLS

6.

One of the most overlooked significance of cell specialization

a)

PRESERVE THE GENETIC MATERIAL

b)

REPLACEMENT OF OLD AND WORN-OUT CELLS

c)

POSSIBLE MEDICAL IMPORTANCE

d)
  1. IMPORTANCE IN CELL-TO -CELL COMMUNICATION 

7.

 are consisted of both living plant cells with very thick cell wall and dead cells.

a)
