Bacteria Unit Vocabulary
| Question | Answer |
|---|---|
| Unicellular | Organisms with only one cell. |
| Binary Fission | Occurs when a single celled organism splits into two cells. |
| Asexual Reproduction | Reproduction with only one cell. |
| Decomposers | Bacteria that feed on dead and decaying organisms. |
| Decomposition | Nature’s process of recycling material. Decomposers release enzymes to break down dead organic matter. |
| Cyanobacteri | The first bacteria that was able to undergo photosynthesis |
| Photosynthesis | During this process organisms (producers) make food as glucose and also produce oxygen. |
| Prokaryotic Cell | The simplest type of cell and only found in bacteria |
| Organelles | Small structures inside eukaryotic cells surrounded by membranes inside the cell |
| Cell Wall | The part of the cell that surrounds the cell membrane and protects the cell |
| Cell Membrane | The part of the cell that surrounds the cytoplasm and lets some material enter and exit the cell |
| Cytoplasm | Enclosed within the cell membrane: gel like yet fluid substance that fills the cell. |
| Ribosome | The part of the cell that builds protein. |
| Deoxyribonucleic Acid (DNA) | The circular strand in the center of the bacteria that “controls” the cell and contains the genes needed for cell growth, survival& reproduction. |
| Capsule | The outer coating that protects the cell. Outside of the cell wall. |
| Flagella | Long whip like protrusion that aids in cellular locomotion. |
| Pilli (Pilus) | Hair like structures on the surface of the cell that help bacteria attach to surfaces. |
| Coccus | Round shaped bacteria |
| Bacillus | Rod shaped bacteria |
| Spirillum | Spiral shaped bacteria |
| Staphylo | Clusters of bacteria |
| Diplo | Pair of bacteria |
| Strepto | Chain of bacteria |
| Kingdoms | Large groups of living organisms with some similarity |
| Archeabacteria (Archea) | First form of life. |
| Extremophiles | Archeabacteria that live in extreme or unusual environments that most organisms could not. |
| Halophile | Extremophiles that live in extremely salty environments. (Salt lovers) |
| Methanogens | Extremophile found in swamps, sediments, sewage and buried landfills. Makes methane. |
| Eubacteria | Evolved after Archea |
| Adaptations | Structures, chemicals and behaviors that help organisms survive. |
| Endospore | Bacteria adaptation - A thick wall that surrounds DNA |
| Conjugation | Bacteria adaptation – Allows for new genetic combinations to increase survival. |
