This week i have learned that there are multiple types of algae. I also learned that only specific type can survive in different water types. Different algae such as Batrachospermum and Euglena help determine clean and polluted water. Algae such as Batrachospermum  can only survive in clean water while Euglena can survive in heavily polluted water.

2. This algae can fix it's own nitrogen.



Pandorina
