| Question | Answer |
|---|---|
| 2. Some bacteria have a _________ that surrounds the cell wall. It is composed of an organized layer of sticky sugars that __________________________________. It is also a protective layer that ________________________. | Some bacteria have a capsule that surrounds the cell wall. It is composed of an organized layer of sticky sugars that help the bacteria adhere to surfaces. It is also a protective layer that deters infection fighting agents. |
| 3. Most bacteria have a _____ _____ that holds the contents of the bacterium together, regulates the amount of water that a bacterium can absorb, and holds the cell into one of three shapes: ___________, __________________, or _________________. The absen | Most bacteria have a cell wall that holds the contents of the bacterium together, regulates the amount of water that a bacterium can absorb, and holds the cell into one of three shapes: spherical (coccus), rod-shaped (bacillus), or helical (spirillum). T |
| 4. Underneath the cell wall (if it exists), there is a _________ ____________, which regulates what the bacterium takes in from the outside world. | Underneath the cell wall (if it exists), there is a plasma membrane, which regulates what the bacterium takes in from the outside world. |
| 5. ________________ exists throughout the interior of a cell, supporting the DNA and the ribosomes. | Cytoplasm exists throughout the interior of a cell, supporting the DNA and the ribosomes. |
| 6. Many bacteria have fibrous bristles called ___________, which are used for grasping. Locomotion is accomplished with a __________________. | Many bacteria have fibrous bristles called fimbriae, which are used for grasping. Locomotion is accomplished with a flagellum. |
| Steady State | A state in which members of a population die as quickly as new members are born |
| Exponential growth | Population growth that is unhindered because of the abundance of resources for an ever-increasing population |
| 1. The term _____________ is often used as a general term that applies to all members of kingdom Monera. Some are beneficial to humans, but some are ___________, which means they cause disease. | The term bacteria is often used as a general term that applies to all members of kingdom Monera. Some are beneficial to humans, but some are pathogenic, which means they cause disease. |
| Pathogen | An organism that causes disease |
| Saprophyte | An organism that feeds on dead matter |
| Parasite | An organism that feeds on a living host |
| Aerobic organism | An organism that requires oxygen |
| Anaerobic organism | An organism that does not require oxygen |
| Exponential growth | Population growth that is unhindered because of the abundance of resources for an ever-increasing population |
| Logistic growth | Population growth that is controlled by limited resources |
| Conjugation | A temporary union of two organisms for the purpose of DNA transfer |
| Plasmid | A small, circular section of extra DNA that confers one or more traits to a bacterium and can be reproduced separately from the main bacterial genetic code |
| Transformation | The transfer of a DNA segment from a nonfunctional donor cell to that of a functional recipient cell |
| Transduction | The process in which infection by a virus results in DNA being transferred from one bacterium to another |
| Endospore | The DNA and other essential parts of a bacterium coated with several hard layers |
| Strains | Organisms from the same species that have markedly different traits |
