Protista for beginners

Protista are organisms that have the characteristics of both plants and animals and cannot go into either group so they are just thrown in here.True protozoans are single celled micro organisms that are classified in the group of phyla in the Protista kingdom.Some examples include amoeba,flagellate,and ciliate.

Science questions

1.The most common organism was the rotifer.

2.It was hard to take pictures of Protista because there was always glare on the microscope lens so it's hard to get good pictures without glare.

3.The most interesting organism was the amphipod because it looks like a tiny shrimp

4.The Rotifers seemed to glide around and it could have been moving using cilia.

5.Amphipods are an important source of food especially in the diets of trout.They are important scavengers and prey in their ecosystems.They mostly eat detritus but they do also eat algae.
