Protist and Fungi

Protozoan: one-celled animal-like organism with a nucleus.
                                       
Cilia: short, hairlike parts on the surface of a nucleus.
                                                       
Sporozoan: protozoans that reproduce by forming spores.
                                                    
Spore: special cells that develop into two organisms.
                                      
Algae: plantlike protist.
                                             
Multicellular: an organism having many different cells that do certain job for the organism.
                                         
Slime Mold: funguslike protist that are consumers.
                                                                 
Hyphae: threadlike  structures that make up bodies of most fungi.
                                                  
Sporangium fungi: fungi that produces spore in sporangia.
                                           
Sporangia:structures,found on the tips of hyphae, that makes spores.
