How cilia functions in Colpidium colpoda . Concept introduction: Colpidium colpoda is is a unicellular eukaryote found in fresh water including lakes, ponds and streams. C. colpoda is used as an indicator for water quality. It survives on bacteria. It has cilia that help in bringing about a movement. Cilia are specialized arrangements of microtubules. Microtubules are hollow tubes of 25nm diameter. It is important for the maintenance of cell shape and motility. Microtubules are arranged in “9+2” pattern. There are two microtubules at the center and nine microtubule pairs at the periphery. At the periphery, microtubules are present in doublet. Cilia carry movement by alternative power and recovery strokes.

You are studying how a newly discovered virus in bats enters their cells. When you examine cells that have taken up the virus, you find virus particles inside clathrin-coated vesicles. What membrane transport mechanismis the virus using to get inside the bat cells? Diatoms are protists that have complex glassy structures in their cell walls. These structures form within the Golgi apparatus. How do these structures reach the cell wall without having to pass through the plasma membrane? What is the evolutionary advantage of bacteria that have flagella vs. bacteria that do not?

The Amoeba, the paramecium, and the euglena ( These are unicellular Protozoans) produce electrical impulses that travel along their cell membrane. This is possible because they are specialized to use properties exhibited by all cells. These properties include ... A) Separation of the fluid environments inside and outside the cell B) Active transport of Na+ out of and K+ into the cell. C) Portal proteins that allow diffusion of Na+ and K+ back in to the cell D) Maintaining unequal Na+ and K+ concentrations on the two sides of the membrane. E) All of these are true Explain why

Paramecia live mostly in freshwater and move with the use of structures called cilia. They utilize contractile vacuoles to expel water that enters the cell by osmosis. Euglena are unicellular organisms that use flagella for movement and chloroplasts for photosynthesis. They are found in freshwater and saltwater. Scientists have determined that Paramecia and Euglena are eukaryotes and not prokaryotes because they have
