Which among the three principles of the cell theory can be practically applied in healthcare by promoting the use of sterilization and disinfection Why do you think so?
One element of the cell theory which is practical applications in healthcare is all cells come from pre existing cells. Yeah because it promotes the use of sterilization and disinfection. We know that all cells come from pre existing cells created through the process of cell division.

What are the cells theory?
In biology cell theory is a scientific theory first formulated in the mid-nineteenth century that living organisms are made up of cells that they are the basic structural/organizational unit of all organisms and that all cells come from pre-existing cells.
What three scientists contributed to the cell theory?
Credit for developing cell theory is usually given to three scientists: Theodor Schwann Matthias Jakob Schleiden and Rudolf Virchow. In 1839 Schwann and Schleiden suggested that cells were the basic unit of life.
What are some examples of cell theory?
For example bacteria which are single-celled organisms divide in half (after they grow some) to make new bacteria. In the same way your body makes new cells by dividing the cells you already have. In all cases cells only come from cells that have existed before.
What type of cells does the cell theory apply to?
What is the second principle of cell theory?
The second part of cell theory was that new cells are formed from preexisting cells. The third part is that all cells are similar. Finally cells are the most basic units of life. In other words everything is made up of cells.
