|
What type of body plan is Kingdom Protozoa?
|
Unicellular
|
|
|
Protozoa is an evolutionary line PARALLEL to ________ but not primitive to them.
|
Metazoa
|
|
|
What type(s) of body structure(s)does K. Protozoa contain?
|
Organelles (nuclei; mitochondria; etc.)
|
|
|
How is Osmoregulation carried out in paramecium? (Phylum Cilophora)
|
Carried out by contractile vacuoles which expel water from their surroundings that is absorbed by osmosis.
|
|
|
Name the four BODY types of Kingdom Protozoa.
|
1. Ciliates (Paramecium)
2. Sarcodinians (Fleshy amebas) 3. Mastigophorans (Flagella/Euglena) 4. Sporozoans (spore-forming/malaria parasite) |
|
|
Paramecium is of which Phylum?
|
Ciliophora
|
|
|
What is the reproduction of Phylum Ciliophora
|
1. Binary fission (asexual)
2. Conjugation (sexual) |
|
|
How does a paramecium move? (locomotion)
|
It propels itself forward by beating cilia that covers its body. It Rotates while it swims. When hitting a solid object, it reverses ciliary motion to go backwars.
|
|
|
What are Trichocysts?
|
Organelles that are used for prey capture or defense from predators by using a spearlike tip that fires from a capsule located below the pellicle.
|
|
|
Paramecium are attracted by _______ conditions.
|
Acidic
|
|
|
Feed of paramecium?
|
AZM
|
|
|
Macronucleus
|
control all vegetative functions.
|
|
|
Micronucleus
|
regulates the reproductive activites of the cell.
|
|
|
The ciliary beating during locomotion uses which principle?
|
Flexible Oar Principle.
|
|
|
what distinguishes ciliates from other protozoans?
|
Nuclei rather than cilia. (dikaryotic)
|
|
|
Describe conjugation
|
2 individuals come together to form a cytoplasmic bridge. Followed by a complex set of divisions and degenerations of macro and micronuclei. Results in an exchange in genetic material b/t the conjugates.
|
|
|
Give examples of ciliate diversity
|
Stentor, Euplotes, Suctorians
|
|
|
What is the phylum and subphylum of The Amoeba?
|
Phylum: Sarcomastigophora
SubPhylum: Sarcodina |
|
|
What maintains the osmotic pressure of Amoeba?
|
Contractile Vacuoles
|
|
|
How does an Amoeba obtain food?
|
Phagocytosis
|
|
|
What is the reproduction of an amoeba
|
Binary Fission
|
|
|
What is a common cellular feature of Phylum Sporozoa?
|
Apical Complex- set of secretory and cytoskeletal structures that enable the young parasite to enter a host cell.
|
|
|
The Flagellates are of what Phylum?
|
P. Mastigophora
**Chloroplasts** |
|
|
Name the 4 flagellates
|
1. Euglena
2. zooxanthellae 3. pfisteria 4. giardia |
|
|
Colonial
|
several organisms of the same species living closely together for mutual benefit (i.e: defense, attack, prey)
|
|
|
Phylogeny of Metazoa?
|
Yes, most take the form of a cluster of cells on a single stalk. Often form plankton clumps.
|
|
|
Phytoflagellates =
Zooflagellates = |
chloroplasts
Glycogen |
|
|
What is the Euglena movement?
|
squeezing, pellicular shape similar to peristalsis.
|
|
|
Choanoflagellates: ancestors of sponges?
|
Yes, they are our nearest living protist relatives. The Dna and basic structures are similar to those of animal sequences (such as sponges). Data shows that choanoflagellates are in same line of evolution.
|
|
|
How do Paramecium excrete?
|
Through cryptopyge.
