When bacteria reproduce by binary fission.... one cell produces two cells What is the function that viruses share with living things? They contain RNAor DNA What is one way bacteria can help the eviroment? They change nitrogen to a form plants can use Which of the following is an example of bioremediation? Usuing microorganisms to clean up an oil spill The gentic material of the virus is inactive within the host cell during The lysogenic cycle How many cells do bacteria have? 1 Archaea can only live in.... hostile enviorments A cell with no nucleus is caled a(n) prrokaryote The domains _____ contain the oldest forms of life on Earth Eubacteria and Archaebacteria what obtains nutrients from other organisms? heterotrophs What uses the body of another living organism to obtain food Parasites What feeds on dead orgnic matter? Decomposers Prokaryotes.... have one cell, can reproduce asexually, are alive, don't have a nucleus Viruses.... have no cells, are not alive, have a nucleus, need a host to reproduce, can't move or use energy, cannot be killed with antibiotics What is an endospore? They surround a bacteriums genetic material, shielding it from any harm. A typical prokaryotic cell has... cell wall, pili, flagellum, ribosomes, DNA, cell membrane, capsule What are some methods bacteria aquire energy to live? Photosynthesis, commensalism, mutualism, decomposing, and parasitism What is Parasitism? A host is harmed and the parasite benefits from it What is Decomposing? When a bacteria feeds off the nutrients of a dead creature What is Mutualism? where both organisms live and benefit from each other. What is Commensalism? when one life form benefits from the other, while the other is neither helped nor harmed What are three strategies that bacteria use to become succesful? They are small (so they can't easilt be seen) Use conjugation to pass genetic material They don't need a lot of energy They eat only a bit Why can bacteria be killed by antiobiotics, but viruses can't? Bacteria are alive while viruses are not What is a vaccine? It is a weaker version of the virus and is given to people to build up immunity. They merely stop viruses from reproducing, but they can't die. What shapes do bacteria come in? Rods, Cones, Spirals What are three types of Archaebacteria? Methane lovers, Salt Lovers, Heat Lover What type of bacteria has cell walls only sometimes? archaebacteria Name 5 dieses caused by a virus: HIV, Pollio, AIDS, Ebola, Rabies Name 4 dieses caused by bacteria: Ecoli, Antherax, Strepp, Cholera Under harsh conditions, certain bacteria form a thick protective layer around their DNA...... Endospores Compare and Contrast a prokaryotic bacterial cell to a virus: Prokaryote: • Has no nucleus • Is living • They divide by binary fission • There is no species barrier Virus: • Has keys • Can only reproduce • Isn't living • Can divide by binary or multiple fission • There is the species barrier How does prokaryotic life aquire energry? By being autotrophic and heterotrophic What is the structure of a "typical" bacterium? A typical bacterium has flagella, cytoplasm, a cytoskeleton, nucleoids, ribosomes, a cell wall, and a cell membrane. T or F: bacteria are eukaryotes: F How can someone get infected after they got a vaccine? the virus could mutate What happens to a virus if it can't enter a host? It can't reproduce What is the species barrier? A virus that has a specific set of locks that can only unlock a specific species. to act as a messenger carrying instructions for DNA for making proteins. RNA What kills bacteria? bacteriaphage
