pond scum and muck?

Question

Suppose you are looking at a sample of pond water, and your see a single celled organism swimming in the water. It's green, and moves quickly.
Hey! I have an answer to this, but I'm not sure if it's right! :)


There's a clear picture of a nucleus, but you can't see any other organelles with your compound light microscope.

In what kingdom does this organism belong? What other characteristics do you expect this organism to have?

Answer 1

If it has a nucleus and is swimming it could be an amoeba, or possibly an Euglena.
If it is Euglena, it will have chloroplasts, an eyespot, will respond to light, and have a flagellum.

Kingdom is Protista
