Question
Know modes of movement in Protista (How do amoeba, paramecium and euglen move?) and which organisms were examples of each. Which one uses cilia, flag pseudopodia? Which organisms were heterotrophs, autotrophs, or both? E ugler The 3 basic shapes of a single bacterial cell as viewed under a microscope. Difference between a single bacterial cell and a colony. (which one can you see microscope?) What type of organism (Protista or bacteria?) and the organism's name that caus malaria. The 2 hosts of malaria. What tissues or cell types can be infecteod? Wh gender of the mosquitoes spread it? Can you recognize amoeba, paramecium and euglena move? from pictures in m and power point notes? Algae are currently classified into which group? (bacteria or Protista) Recognize examples of red, green, diatoms, and brown algae, bacteria from pic (look at our notes and lab manual) -Coralline, Macrocystis, Spirogyra, Ulva. Why are some algae thin and large or spread out? (ike Ulva and Macrocystis) Which group of algae is closest to plants? Why? know anatomy of kelp-stipe, blades, holdfast, air cyst/bladder (float too). What their functions? Why are they not given the same names as a "true plant"? (hint notes on vascular tissue in plants I lab) Commercial uses of algae and bacteria? Which organism uses acid to digest food? Which organism can go from autotrophic to heterotrophic if not enough sunligh organelle does it use if sunlight is available and why? What is the function of the eyespot in this species? Which organism has spiral shaped chloroplasts? 17. what type of staining did we use to view bacteria that may cause tooth decExplanation / Answer
Kingdom protista :
All single cell eukaryotes are placed under protista.
It includes
1)Chrysophytes
2) Dinoflagellates
3)Euglenoid
4)Slime moulds
5) Protozoan
Protozoans are further divided into
1)Amoeboid :
They move and capture their prey by putting out pseudopodia.
e.g) Amoeba
Pseudopodial Movements
It is slow creeping type of locomotion which is performed with the help of protoplasmic outgrowths called pseudopodia.
2) Flagellated :
They are either free living or parasites.
They have flagella.
e.g) Trypanosoma
Flagellated movement :
Flagella show whip-like movement. They usually beat independently.
Dianoflagellate also perform this movement.
3) Ciliated :
These are aquatic, activly moving organism because of thousands of Cillian.
e.g) Paramecium
Ciliated movement :
Cilia show oar-like movement. All the cilia of a cell show coordinated movements which are of two types, isochronic and metachronic rhythms. In isochronic or synchronous rhythm, all the cilia of a cell beat simultaneously. They do so in rapid succession one after the other in case of metachronic rhythm.
4)sporozoane :
They have an infectious spore like stage in their life cycle.
e.g)Plasmodium
The organism causing malaria.
Plasmodium falciparum
Plasmodium vivax
Plasmodiu malariae
Plasmodiu ovals
2 hosts
definitive host : female anopheles mosquito
intermediate host : Human
Tissue which affects first by malaria is liver. Spleen is also affected resulting in the splenomegaly
They are infecting the red blood cells(RBC) in human body.
Heterotrophs :
Heterotrophs rely on autotrophs to provide a continuous supply of new organic molecules.
Animal , fungi, many bacteria
Autotrophs :
Autotrophs are organisms which are able to make their own organic molecules
e.g)Plants , Algae, many bacteria.
Shapes of bacterial cells
1) Coccus(spherical)
e.g,) Staphylococcus, streptococcus
2) bacillus (rod-shaped)
e.g) Bacillus anthracis
3)spiral (twisted) :
e.g) Treponema pallidum
4) Vibrio (comma shaped) :
e.g) Vibrio cholerae
