Symbiosis (Interdependence 2)

Symbiosis is a way to describe a relationship between two organisms. It is classified differently according to whether the relationship benefits both or only one side.
Today we discussed the nature of symbiosis, its many types, and scrutinised one form of symbiosis which is lichen.
The existence of lichen is actually a result of a mutually beneficial relationship between an alga and fungus. We discussed this symbiosis and inspected some lichens under the microscope. Then the students went off to find more samples of lichen of their own.

The second picture shows lichen under a microscope much more powerful than ours.
