Bacteria Questions. Rigid protective structures around cells are called cell walls. Bacteria are cells and are surrounded by rigid protective structures. So, bacteria have cell walls. 1. What are the rigid protective structures around bacteria called? Bacteria Questions. Genetic material in eukaryotic cells is contained inside a nuclear membrane making a nucleus. The genetic material of prokaryotic cells is not in a nucleus. Bacteria don’t have nuclei, so they are prokaryotic cells. 2. What term describes bacteria? Bacteria Questions. Bacteria are unlike eukaryotic cells in that they don’t have a nucleus. Since bacteria don’t have nuclei, they are prokaryotic cells. Bacteria are like eukaryotic cells in that they have ribosomes in their cytoplasm. Cytoplasm is not a structure. 3. Compare and contrast bacteria to eukaryotic cells. Bacteria Questions. Bacteria can go into a resting state if conditions become unfavorable. Lack of food, oxygen, or hash temperatures can cause bacteria to form endospores. Bacteria form endospores during extreme conditions. Small ones can drift around. 4. How do bacteria respond to extreme conditions? Bacteria Questions. Sourdough bread, cheese and vinegar are all produced with the help of bacteria. Bacteria give the bread its sour taste. Bacteria also change juices into vinegar and milk into cheese or yogurt. 5. What gives sourdough bread its sour taste? Bacteria Questions. Bacteria produce energy using the process of respiration. Sugar is broken down by cells using the process of respiration to produce energy. Bacteria are cells, so bacteria produce energy using the process of respiration. 6. What is it called when bacteria breakdown sugar to produce energy? Bacteria Questions. A decomposer breaks down large chemicals into smaller ones. Bacteria are decomposers, so they break down large chemicals into smaller ones. Decomposition by bacteria helps recycle chemicals in dead organisms and can help in environmental cleanup. This shows not all bacteria cause disease. 7. What do decomposers do? 8. Do all bacteria cause disease? Conjugation is the process by which genetic material is passed from one bacterial cell to another through cell to cell contact. The bacterium that receives the new genetic material is genetically different after conjugation. 9. What process results in bacteria becoming genetically different? Bacteria Questions. Bacteria increase in number through binary fission. Binary fission starts with one cell and ends with two cells. The genetic material of the two cells produced is exactly alike. Binary fission is how bacteria reproduce. 10. In bacteria, cells with identical genetic material are produce by what reproductive process? Bacteria Questions. Binary fission is the process bacteria use to reproduce. One cell becomes two cells through this process. The two resulting cells are genetically identical. 11. How does the genetic material compare between the two new cells produced by binary fission? Bacteria Questions. Good Bacteria. Bacteria Questions. . Bacteria Questions. Bacteria Questions.
