Protist | generally, a single-celled organism with a nucleus and organelles; including amoebas, euglenas, paramecia, and volvox |
Pseudopod | an extension of the cytoplasm used for movement in some organisms; a means of locomotion for an amoeba; literally "false foot" |
Virus | particle consisting DNA encased in a protein coat that injects its DNA into a living cell to reproduce; a microbe that consists of nucleic acid enclosed within a protein shell that requires living cell to reproduce; scientists consider virus not alive |
