This was taken under OIO, and it’s mixed but we were asked to name some or preferably the dominant algal species. But I am confused on what they actually are.

Also, we took this from a freshwater (man-made) pond inside the campus. From what I remember, there were hair-like algae present along with it.

Help also why does this keep getting removed when algal isolates can be identified morphologically without staining
