| Question | Answer |
|---|---|
| Ammonia | Usable form of nitrogen for both eukaryotes and prokaryotes |
| Biofilm | Community of microorganisms in which cells stick to each other and often also to a surface |
| Pillus | specialized, hair-like protein appendage on the surface of certain bacteria that facilitates the direct transfer of genetic material |
| Flagella | long, whip-like structures that protrude from cells, primarily enabling locomotion in liquid environments for various organisms |
| Plasmid | Smaller circular DNA in prokaryotes |
| Endospore | Bacterial cells resistant to water and nutrient depleted environments, which can survive dormant for centuries |
| Taxis | Movement to or away from a stimuli |
| Hypotonic | cell environment has a lower solute concentration than the cell, causing water to move into the cell which leads bursting |
| Fimbriae | Prokaryotes hair like appendages, allowing for interlocking between cells |
| Peptidoglycan | substance forming the cell walls of many bacteria, consisting of glycosaminoglycan chains interlinked with short peptides |
| Obligate aerobe | Prokaryote which requires oxygen for cellular respiration |
| Obligate anaerobe | Prokaryote which cannot use oxygen for cellular respiration and are poisoned by it. Can use fermentation for energy |
| Facultative anaerobe | Prokaryote which can use oxygen for cellular respiration, and execute anaerobic respiration. |
| Nitrogen | Element eukaryotes are unable to use |
| Horizontal Gene Transfer | non-sexual movement of genetic information between genomes. |
