Slide 2 : 1.Sukhsimran found an organism in a pond, and she thinks it's a freshwater sponge. Her friend, Simar, thinks it looks more like an aquatic fungus. How can they decide whether it is an animal or fungus ?
Determine whether it is unicellular or multicellular
see if it is a eukaryote or prokaryote
look for cell walls under a microscope
figure out whether it is autotrophic or heterotrophic
none of the above determinations will help their decision

Conifers
Sea Stars
Insects
Slide 15 : Ferns exhibit an alternation of generations in which there is a regular alternation of two different forms
