## LEARNING AIDS
	**Common Mistakes**:
		1.[Error 1]: Assuming lichens only grow in polluted areas. [How to avoid]: Remember that lichens are sensitive to pollution and are good indicators of clean air.
		2.[Error 2]: Confusing the terms phycobiont and mycobiont. [How to avoid]:  Phycobiont refers to the algal component, and mycobiont refers to the fungal component.
	**Quick Tips**:
		1.[Helpful shortcut]: Remember that lichens are both pollution indicators and also sensitive to pollutants, hence they are good indicators of clean air.
		2.[Memory aid]: Think of 'phyco' as relating to the plant-like component (algae).
