Danish scientist Hans Christian Gram devised a method to differentiate two types of bacteria based on the structural differences in their cell walls. In his test, bacteria that retain the crystal violet dye do so because of a thick layer of peptidoglycan and are called Gram-positive bacteria. In contrast, Gram-negative bacteria do not retain the violet dye and are colored red or pink. Compared with Gram-positive bacteria, Gram-negative bacteria are more resistant against antibodies because of their impenetrable cell wall. These bacteria have a wide variety of applications ranging from medical treatment to industrial use and Swiss cheese production.

<span>Osmosis is defined as the movement of water across a
semipermeable membrane from high concentration to low concentration. This
occurs when the surrounding environment of the cell has a higher water
concentration than the cell itself. Osmosis is important in animal cells
because it helps in the distribution of nutrients and the release of metabolic
waste products. In plant cells, osmosis is responsible for the absorption of
water from the soil and the elevation of the liquid into other parts of the
plants.</span>
