| A | B |
|---|
| smallest between viruses, prokaryotes, and protista | viruses |
| three things that limits the growth of microorganisms | waste build up, decreased nutrients, preditors |
| What do all of these have in common: hydrogen sulfide, nitrites, sunlight, ammonia | all can be used as energy sources for bacteria |
| name of spherical bacteria | cocci |
| name of spiral bacteria | spirilla |
| Gram positive bacteria | purple color, reacts with crystal violet |
| pili | allows two bacteria to join together to transfer genes |
| What do all of these have in common? | flagellum, pilus, capsule, peptidoglycan |
| plasmid | circular DNA found in bacteria, can be used for gene amplification, may be transferred to different bacteria |
| conjugation | the process of one bacteria cell transferring DNA to another bacteria cell |
| where could you find methanogens | swamp, decomposing material |
| where would you find thermophiles? | waste piles of coal mines, hot springs |
| what does archaebacteria lack that eubacteria has? | peptidoglycan |
| what are some examples of archaebacteria | methanogens, thermoacidiphiles, halophiles |
| this is formed by some bacteria in order to survive nutrient scarce conditions | endospore |
| autoclaves use this to kill bacteria | heat and pressure |
| this bacteria is found in the human gut, produces vitamin K, helps digest fats, and can cause illness | E. coli |
| Four things that bacteria, a single celled organism, can detect | light, magnetic field, gravity, osygen |
| viruses are not considered alive because... | they have to use the host cell's organelles and energy in order to reproduce |
| a virus is made of... | a unique protein coat surrounding either DNA or RNA |
| retrovirus | RNA core, reverse transcriptase, cause of AIDS, temperate |
| simplest eukaryote | protistans |
| animal like protistans | protozoans |
| how are protozoans classified | by movement (sessile, cilia, flagella, pseudopods) |
| Plants like protistans | algae: classified by color |
| protista with pseudopods | amoeba, foraminiferans, heliozoans, radiolarians |
| protista that moves by cilia | paramecium |
| What is the function of the gullet | ingestion of food |
| what is the function of the cilia | movement and food gathering |
| what is the function of the contractile vacuole | rid protostan of excess water |
| what is the function of the trichocysts | defense |
| what is the function of the pellicle | structure |
| what is the function of the eyespot | detects light and dark |
