Lecture 10 Excavata
| Question | Answer |
|---|---|
| Protists are unicellular or Multicellular? | Unicellular |
| What is the Diversity of Protist | Most are unicellular and some are colonial, multicellular, and multinucleate. |
| What is a multinucleate | a multiple of nuclei |
| What are the multinucleate features | no cell wall or plasma membrane |
| What occurs in multinucleates? | Mitosis without cytokinesis |
| What are the 3 types of protists. | Autotrophic, heterotrophic, and mixotrophic |
| where do protists live? | aquatic area marine or freshwater |
| What is a Protozoan | Animal like protist |
| What are slime molds | Fungus like protists |
| What are algae | Plant like protists |
| Do protists represent a true clade? | no |
| what is the first protist in the excavata branch | Diplomonadida |
| What are the diplomonadida Charcterisitic | Unicellular heterotrophs move using multiple flagella reproduce asexually no cell wall two nuclei Primitive mitochondria |
| What is giardia | A parasite in humans |
| What does giardia cause. | Severe diarrhea |
| What is the 2nd protist of the Excavata Branch | Parabasalida |
| What are the cahertisitic of Parabaslida | Unicellular heterotrophs Move using multiple flagella reproduce asexually no cell wall one nucleus Primitive mitochondria |
| Where are the parabaslids located | Parabaslids are entirely symbiotic within animals. (live insde of animals) |
| Trichonympha | Breaks down the cellulose of lignin in wood |
| trichomonas | Live parasitically within the human urogenital system |
| Trichomoniasis | A sexually transmitted disease that result in infections of the female system |
| What branch is Kinetoplastida in. | Discicristata branch |
| What are the characteristic | unicellular heterotrophs Move using two flagella reproduce asexually no cell wall a single full functional mitochondrion |
| Where is kinetoplastida found | in marine, freshwater or damp terrestrial enviroments |
| What type of kinetoplasts are parasitic | Trypanosoma |
| What is Trypanosoma | African sleeping sickness and Chagas disease |
| Euglendia | 2nd protist in the Discicristata branch |
| What are the chacteristics of Euglendia | Unicellular mixotroph, moves using one long flagellum, reprodu ce assexually, no cell wall |
| What is replaced with the cell wall in euglendia protists. | a pellicle (priten sheet) lies directly beneath the plasma membrane |
| Where is euglendia located | mostly freshwater ( a few marine) |
| Is euglendia a phytoplankton | yes under the euglendia group |
| What do contractile vacouoles do? | Store and expel excess water in freshwaterr habitats |
