THE KINGDOM PROTISTA The Protozoans PROTOZOAN CHARACTERISTICS
animalcules first animals eukaryotic motile often rapid movement aquatic microscopic unicellular
a few colonial heterotrophic some parasitic, some beneficial to host PROTOZOAN CHARACTERISTICS (CONTINUED) primarily asexual reproduction
(binary fission) exchange of genetic information possible in a few species eyespots to detect light intensity cysts protect during harsh environmental conditions Members of the kingdom Protista are a. prokaryotic.
b. eukaryotic. PROTOZOAN PHYLA Sarcodina Ciliophora Zoomastigina Sporozoa chart on page 257 compares the 4 phyla
PHYLUM SARCODINA CHARACTERISTICS common name - sarcodines no standard body shape flexible plasma membrane heterotrophoic, some parasitic movement by pseudopodia false feet (amoeboid
movement) Examples: amoebas, GENUS AMOEBA Cytoplasm is divided into 2 parts: endoplasm the dense cytoplasm found in the interior of the cell
ectoplasm the thin cytoplasm on the outer perimeter of the cell GENUS AMOEBA nucleus controls metabolism contractile vacuole eliminates water, regulates homeostasis
amoeboid movement constant change in shape by formation of pseudopodia pseudopod extension of a cell used for locomotion and engulfing substances GENUS AMOEBA
nutrition pseudopodia engulf food and form food vacuoles taxis a response to a stimulus reproduction binary fission no known form of sexual reproduction form cysts
Show youtube videos A contractile vacuole a. engulfs food particles. b. collects and eliminates wastes. c. collects and eliminates excess water. d. keeps the cell rigid.
What term describes this process of engulfing food? a. phagocytosis b. pinocytosis c. autophagy d. egestion AMOEBIC DYSENTERY Most
sarcodines are nonpathogenic to humans Entamoeba histolytica spread by contaminated food and water symptoms intestinal ulcers bloody diarrhea possibly death (not likely today)
PHYLUM CILIOPHORA CHARACTERISTICS common name ciliates heterotrophic some parasitic cilia free-swimming
Examples: Paramecium, Stentor, Vorticella GENUS PARAMECIUM macronucleus contains multiple copies of genetic material micronucleus
functions exchange of genetic information in sexual reproduction GENUS PARAMECIUM pellicle firm yet flexible outer covering results in slipper shape cilia
completely covers Paramecium Enables to turn, rotate, and travel in any direction oral groove opening for the passage of food leads through the mouth pore to the gullet GENUS PARAMECIUM avoiding reaction
movement trichocysts discharge filaments in response to stimuli (defense mechanism) reproduction asexual binary fission sexual conjugation Show youtube video macronucle
us micronucle us contractile vacuole food oral groove
mouth pore vacuole gullet PHYLUM SPOROZOA CHARACTERISTICS common name sporozoans heterotrophic
no special mode of locomotion form spores asexual & sexual reproduction nutrition all sporozoans are parasitic. Example: Plasmodium MALARIA caused by a sporozoan
Plasmodium carried by a female mosquito Anopheles symptoms chills and high fever Anemia
PHYLUM ZOOMASTIGINA CHARACTERISTICS common name zooflagellates heterotrophic, most unicellular some parasitic flagella for movement reproduction
asexual by binary fission some sexual Examples: Trichonympha,Trypanosoma,
AFRICAN SLEEPING SICKNESS carried by the tsetse fly symptoms brain inflammation mental lethargy sleepiness possibly death
VirtualHealth Implementation Update, cont. VH immediately identified that the allocated 10 Workstreams would not be enough to complete critical items by go-live and volunteered an additional 2 Workstreams + extra migration work outside the 12 Workstreams
