 Microbe | short for microorganism which means small organism - observed with a microscope |
| 99 | % of microbes contribute to the quality of human life |
| Prions | Infectious agents composed primarily of protein which induce the existing polypeptides in host cells to take on its form. |
| Prokaryotic | single cell with nuclear material but no nuclear membrane or membrane bound organelles |
| Eukaryotic | most cells - with organized nucleus and membrane bound organelles |
| Mitochondria and Chloroplasts | have DNA similar to that of a Prokaryotic cell and can reproduce independent of the rest of the Eukaryotic cell |
| Bacteria | has only one cell, lives in all environments. |
| small minority | A _____ ________ of microbes cause disease in humans by sheer numbers or producing powerful toxins. |
| bacteria, Archaea, algae, fungi, protozoa, and viruses | major groups of microbes are: |
| Microbes | In terms of numbers, what represent most of the diversity of life on earth and are found in every environment? |
| Acellular | Viruses do not have cellular components, nor do they grow or metabolize organic materials. Generally consist of a piece of nucleic acid encased in protein which must use the cellular components of a living cell to reproduce. |
| Prions | proteinaceous infectious particles |
| Prions | infectious agents composed primarily of protein which induce the existing polypeptides in host cells to take on its form. |
| Cell Wall | what part of the cell is for protection and support? |
| Chloroplast | what, in plants, is for photosynthesis? |
| Prokaryotes, Eukaryotic | It is believed that both chloroplasts and mitochondria were one independent ___________ who took up residence in the __________ cell and have developed a special symbiotic relationship. |
| prokaryotic | kind of cell that is in bacteria |
| one | how many cells are in bacteria |
| all environments | where do bacteria live? |
| sherical, rod, spiral | shapes of bacteria |
| bacteria | some form spores |
| photoautotrophic | bacteria that make their own food as plants and give off oxygen |
| aerobic | Cyanobacteria and purple and green bacteria are..... |
| chemoautotrophic | bacteria that synthesize their own food using energy from chemical reations. |
| recycling in nitrogen and sulfur cycles | what are chemoautorphic bacteria important for? |
| flagella | What do some bacteria have that rotates like a tiny outboard motor? |
| slime like slugs | how do bacteria that don't have flagella move? |
