Cell Growth and Multiplication

The individual cells have the capacity to grow. They do this by acquiring
various substances from the blood and converting them into appropriate cellular
elements.

Sometimes, a tissue such as muscle tissue will increase in mass without an
increase in the number of units. This condition is called hypertrophy.

Cell Multiplication
If an increase in tissue mass results from a greater number of cells, we refer to this a
hyperplasia.

Cell multiplication is accomplished through a process called mitosis.
In mitosis, the genetic material of the cell is doubled. Then, the cell divides into two halves.
One-half of the genetic material goes into each of the two daughter cells. In this
manner, the two new cells each have the same genetic composition as the original cell.
