- Gram staining is a staining techniques used for the identification of bacteria in microbiological studies.
- Gram staining uses crystal violet as the primary stain. It complexes with the peptidoglycan cell wall of Gram positive bacteria giving them a purple color.
- An iodine mordant is also used that forms a crystal violet-iodine complex that fixes the crystal violet dye to the cell wall. This prevents the Gram positive cell walls from being decolorized by the application of alcohol.
- A counter stain, safranin is then applied that stains Gram negative bacteria pink.

The physical space between the presynaptic and postsynaptic neurons is called the synaptic cleft
and the chemical that is released to signal across this space is called a neurotransmitter
Explanation:
A synapse is the junction between dendrites of two adjacent neurons. Its function is to allow the transmission of nerve impulses from neurone to neurone. Tn the presynaptic knob there are vesicles which contain a transmitter substance which is usually acetylcholine. The acetylcholine diffuses from the presynaptic membrane to the postsynaptic membrane.
