    * All living organisms are made up of cells. * Many unicellular organisms are aquatic. Often they possess either cilia or flagella helping them move around in their environment. * As a cell increases in length (provided its shape remains the same) its surface area: volume ratio decreases. This makes it difficult for it to obtain sufficient "nutrients" or rid itself of wastes to survive. * Viruses are infectious particles. They are not cells.
