The cells go through the cell's membrane
Cellular differentiation is for cells that are to become specialized parts of a larger organism. Think along the lines of brain cells, skin cells, heart, cells, etc. Unicellular organisms are, by definition, a single-celled organism, and that is why they do not go through cellular differentiation.

Somatic cells do not go through meiosis because they are not involved in the formation of eggs or sperm. Meiosis is specifically for the production of gametes (sperm and eggs) in organisms for sexual reproduction. Somatic cells undergo mitosis to produce new somatic cells for growth and repair.
Most body cells go through mitosis, including skin cells, muscle cells, and blood cells. Germ cells, which develop into sperm and eggs, also go through mitosis.
Your body does not go through mitosis, but rather your cells do. The cells in your body go through mitosis to reproduce. This is how non-sex cells, or somatic cells make more of themselves. Sex cells do not go through mitosis, but instead go through meosis.
Because the materials can go through the small cell faster

No, not all cells go through mitosis. Mitosis is a form of cell division that occurs in somatic cells to produce two identical daughter cells. However, cells such as sex cells (sperm and egg cells) go through a different type of cell division called meiosis.

Plants, algae, and some bacteria are organisms that go through the process of photosynthesis.
Somatic cells, also known as body cells, go through mitosis.

Quite contrary from the previous answer which was 'I do not know that all organisms go through mitosis. I would imagine most do, it is the means by which development occurs, and multicellular organisms are created through this process, perhaps single celled organisms do not go through this process as they are complete as single cell entities. Perhaps we have a biologist out there whom could give us more detail or inform us of exceptions to the rule. http://en.wikipedia.org/wiki/Mitosis Mitosis--Cell division in which the nucleus divides into nuclei containing the same number of chromosomes' the organisms cells inside of him/her may go through mitosis, but most organisms in order to reproduce actually go through meiosis, the opposite of mitosis when mitosis is asexual (one parent) and meiosis is sexual(2 parents.) most things that go through mitosis would be bacteria. multicellular organisms and unicellular organisms aren't necessarily in either category.
Adding more cells
Just explain that micro organisms are made up of cells, can grow, can reproduce, and that they go through stages of developement and evolve.
The cells in your body require energy to function. To get this energy the cells go through a process called respiration. The cells use glucose(sugar) and oxygen to form energy, water, and carbon dioxide. Blood carries oxygen, glucose, and other materials to cells. If the cells are vigorously used (which happens a lot in muscle cells) the use all the materials the blood can provide them. After resting the cells get materials from the blood again and can function more and are less tired.
