    Unicellular organisms may use several methods to move around. These include the use of flagella and cilia

    For the first time in this course, I find that this section is not very well explained. The videos for both cilia and flagella do not explain enough to answer the three questions. I needed to research elsewhere to answer them...

    this section is so confused as well as the two video of cilia and flagella. there is no definition given for cilia and flagella. I need to know what they are in order to answer those questions.

    Define 'cilia' and "flagella" : Swimming is the major form of movement exhibited by sperm and by many protozoans. Some cells are propelled at velocities approaching 1 mm/s by the beating of cilia and flagella, flexible membrane extensions of the cell. Cilia and flagella range in length from a few microns to more than 2 mm in the case of some insect sperm flagella. Although cilia and flagella are the same, they were given different names before their structures were studied. Typically, cells possess one or two long flagella, whereas ciliated cells have many short cilia. What organisms have cilia, and witch ones have flagella? Even simple bacterial cells include various structures that have their own intricately arranged components. Two fascinating examples of this complexity are cilia and flagella, which accomplish various types of microscopic movement.The organisms which bear cilia over their body mostly belong to the category of ciliates. e.g Paramecium, Stentor. The organisms which bear a special structure called flagellum aiding in locomotion belong to the category of falgellates. e.g.Trypanosoma and Giardia are two flagellate forms. What does cilia help an organism to do? The movement of these appendages allows the cell to move or to fulfill specific tasks, like assisting in transporting external substances. How do unicellular organisms move around? To move around, a protist, such as a paramecium, has hair-like structures called cilia, while an amoeba has pseudopodia, which are feet-like appendages that extend from its cytoplasm. Flagella are whip-like structures used by a flagellate like euglena for locomotion.

    Cilia and flagella are unicellular organisms. there are many ways in which a unicellular organism can move around and get food. A large amount of unicellular organisms lives in water and they are called aquatic.
