it just does
Cells grow in order for the organism to grow and reproduce. Cells only grow to replace other cells that die off and allow for the continued existence of the organism.
bacterial cells compare to the inside body to the sperm cell. other than that they do really compare to anything.
An organism whose cells lack a nucleus and some other cell structures is called a prokaryotic organism. If the cells had a nucleus then the organism would be eukaryotic.
Every organism are made of cells. Other wise they are not considered living.

Jellyfish are composed of cells just like any other organism is.
Humans and every other animal.
you and every other living organism are made up completely of cells.
Cells of an organism tell each other when predators are nearby. :)
Absorbing other cells gave a competitive advantage.
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.
In a multicellular organism, the cells are specialized and organized into different tissues and organs to carry out specific functions. These cells communicate and coordinate with each other to maintain homeostasis and support the overall functioning of the organism. They have distinct roles and structures, such as nerve cells for communication, muscle cells for movement, and skin cells for protection.
