Eukaryotic Protist Flashcards
Protozoan -xtics And Classification
state the general xtics of Protists
*unicellular eukaryotic organism. *lack cellulose wall. *are generally colourless. *usually found in freshwater habitat. *usually feed by phagocytosis/pinocytosis
what are the major divisions of Protists
Sarcodina, Mastigophora, Apicomplexa, Ciliophora
What are the major divisions of Phylum sarcodina??
Rhizopoda, Actinopoda, and Foraminifera
which parasitic amoeba is responsible for amoeba I’d dysentery ???
Entamoeba Histolytica: by ulceration of the intestinal tract causing diarrhoea condition
which phylum of Sarcodina lacks meiosis, flagella, and cell wall
Rhizopoda
what is the component of the tests of foraminifera??
made up of calcium carbonate and sand
explain the essence of cytoplasmic extensions/projections from forams??
Such extensions are called PODIA, and that are used for swimming, feeding, gathering materials for the shell…
another name for phylum actinopoda???
Radiolarians
which forms of sarcodina are exclusively marine organisms ??
Forms and Radiolarians
name some genre of Phylum mastigophora
Trypanosoma, Cnthidia, Codosiga, Trichonympha, garida
an example of a species of trypanosoma that causes trypanosomiasis ??
Trypanosoma gambiese
describe the inhibition characteristic of the Trypanosome gamibiense(how is moves within the human body)?
It grows and lives in the blood…then invades the central nervous system (CNS), causing inflammation of the brain and spinal cord, hence neurological symptoms and effects.
what is the causative vector of trypanosomiasis???
Tsetse fly (Glossina. sp)
how are ciliophoras mobile??
means of cilia anchored to microtubules beneath the cell membrane
diffrenctiat between the two kinds of nuclei of ciliophora??
Micronucleus: For sexual reproduction. Micronucleus : for production of mRNA, for cell growth and functions
