|
Characteristics of Amoebas (phylum RHIZOPHODA) |
- have pseudopods: movable extensions of cytoplasm used for movement and food - no flagella - asexual reproduction |

|
|
sessile |
attached to a substrate |
|
-phylum -genus -KC |
Phylum: CILIOPHORA Genus: Vorticella KC: sessile; contractile stalk attaches organism to the substrate; has a cell body with crown of cilia |
|
-phylum -genus -how does this organism feed? |
phylum: CILIOPHORA genus: Vorticella to feed: extends contractile stalk to push cell body far away from substrate and other organisms, the rapidly beats its cilia to capture food particles |
|
-phylum -genus -KC -what disease does it cause and what is it transmitted by? |
-Phylum: APICOMPLEXA -Genus: Plasmodium -KC: located within the blood cell -malaria transmitted by mosquitos (of genus Anopheles) |
|
|
Characteristic of APICOMPLEXA (what are they usually) |
-nonmotile animal parasites |
|
|
cytoplasmic movement occurs in this specimen. what is its: -phylum -genus -KC |
-Phylum: DICTYOSTELIA -Genus: Plasmodium -KC: 1. coenocytic (multinucleate): has nuclei that are no separated by cell walls 2. if food supply or moisture decreases plasmodium dry into a hard resistant structure called scerotium and remain dormant until conditions improve |
