Endospores
This is a small video clip which illustrates the formation of Endospores in bacteria. Leaving Cert Biology Students don't need to know all the detail but is a clear representation of what happens. Don't get bogged down by the chemistry! Know why and when they are formed and be able to explain in a simple way for your final exam.
