Phylum Sarcodina Characteristics
*Characterized by a lack of a standard body shape.
*May form extensions that function as false feet or pseudopods.
*They live in a variety of habitats including fresh water, the sea floor, and the human mouth and intestines.
Be able to label these parts of an amoeba
When all of the endoplasm from a protist moves to one area of the plasma membrane forming a pseudopod, and the rest of the organism then flows along with it.
Phylum Ciliophora Characteristics
*All organisms in this phylum contain cilia.
*The organisms in this phylum live in stagnant lakes & ponds.
Be able to label these parts of a paramecium
In a paramecium, this contains many copies of the genetic information and helps in day to day activities.
Food pathway for a paramecium
Cilia that line the oral groove sweep food into a short tube called the gullet. At the end of the gullet a large bulge forms forming a food vacuole.
When the micronucleus divides by mitosis, and the macronucleus enlarges and divides in half. The protist elongates and a second gullet forms. A furrow forms across the middle of the protist and it divides in half.
When two protists attach to each other by their oral grooves, exchange nuclear material, and then divides into 4 organisms.
Phylum Sporozoa Characteristics
*As adults, organisms in this phylum do not have any structures for movement.
*This phylum forms spores at some point during their life cycle.
A cell with a hard, protective covering that forms during times of extreme or harsh conditions.
How does malaria get passed on from person to person.
The mosquito "bites" a person that has the plasmodium sporozoan in their bloodstream. The plasmodium cells go to the mosquito's salivary glands. Before feeding on the blood of another human, the infected mosquito injects some of its saliva, containing the Plasmodium parasite, into the puncture wound of this new victim. The Plasmodium goes to the human liver cells, reproduces quickly, and then enters the bloodstream causing those cells to burst and fully infect the human.
