Mitosis.
growth
Organisms grow by cell division or mitosis which causes increase in number of cells , and then by increase in size of cell .
Hyperplasia
Although weight and mass make organisms differ from each other, it is the number of cells the organism has that makes it its size. Likewise, the more cells the organism has, the bigger it is. The number of cells, not the size of the cells, determine the weight and mass the organism has. Example: An elephant is obviously much bigger than a bear, but due to the fact that it is composed of a greater number of cells.

Hyperplasia
They can grow by increasing their cytoplasm(to a certain point) They can grow by dividing and increasing the number of cells. And depending on your definition of grow, a multicellular organism could grow by increase the amount of interstitial fluid.
it is actually called an organism.

system of classification using structural characterisistcs
Growth of an organism is characterized by an increase in the size of its body. This occurs due to accumulation of food substances in the cells which in turn increases the volume of the protoplasm in the cells. This increase in volume of cells results in growth. However, its necessary to understand the fact that cells do not increase in their volume indefinitely. After a considerable period of time they divide into two through processes such as mitosis. These divided cells again increase in volume and redivide after they become large. Bassicaly, the organism eats and gets nutrients from what it eats which causes it to grow.
