Question

Which element of the cell theory has practical applications in health care because it promotes the use of sterilization and disinfection?
(A) All cells come from pre-existing cells.
(B) All living organisms are composed of one or more cells.
(C) A cell is the basic unit of life.
(D) A nucleus and organelles are found in prokaryotic cells.​

Answer 1

The element of the cell theory having practical application in health care is (A) All cells come from pre-existing cells.

• The cell theory was brought forward by Schleiden and Schwann. One of the main postulates of this theory was that all cells arise from pre existing cells.
• As cells arise from pre existing cells, this means that the microbes present in blood, cells or environment all the time have the tendency to multiply. As these microbes can be harmful hence in health care, it is important to sterilize a surface and every equipment being used so that microbes can be killed and their further growth from pre existing cells can be stopped.
• Hence, the postulate of the cell theory that 'All cells come from pre-existing cells' promotes the use of sterilization and disinfection.
