Calculating Magnification
Actual size = Image size / Magnification
Magnification = Image size / Actual size
Cells
Prokaryotic
Do not contain membrane bound organelles such as a nucleus and mitochondria.
bacteria cell
They are simple structures
Eukaryotic
Made up of multicellular organisms and contains a nucleus
Plant and animal cells
Gram Staining
There is approximately 10,000 bacteria identified
Gram Negative
Thinner cell wall and membranes allows ethanol to wash off the purple crystal-violet stain
Pink safranin stains
Gram Positive
Thick cells wall retains the purple crystal-violet stain
Purple stains
Action Potential and Synapse
Synapse
Transmission of electric nerve impulses between two nerve cells
Action Potential
When an action potential is not being transmitted, the neuron is maintaining an action potential
The movement of an impulse across a neuron
