Flagella is used for cell motility in eukaryotic cells only e True False
32 Exercise 6 Determination of Motility QUESTIONS 1. How do prokaryotic and eukaryotic flagella differ? 2. How should you dispose of a hanging drop slide? 3. Why is it important to be able to determine motility? 4. Why are bacterial flagella not visible with a light microscope? 5. Which of the three methods of determining motility allow distinguishing of flagella arrangements?
List the two major motility systems and eukaryotic cells. Name the cytoskeletal elements and motor proteins associated with each.
33 Which of the following structures involved in motility (movement) do Eukaryotic possess, but Prokaryotes do not? A. Flagella B. Cilia C. Capsule D. None of the above,40 What type of bacteriophage life cycle is being depicted here? What part of the life cycle is indicated by the number 41 What is the function of the lysozome?42 What is the structure denoted by the number 2, and what is its function within the cell?
Print Only germ cells have sex chromosomes. True or False True False e 19 2 13
If the statement is False make it true, if it’s true then state that’s its true 73) Bacteria cannot reproduce unless they are inside a host cell. 74) The first antibiotics were discovered in fungi. 75) Fungi use antibiotics to kill viruses in their environment. 76) Biofilms are complex communities of bacteria, fungi and protists. The organisms communicate with chemical signals and have different jobs to do 77) Apicomplexans move with cilin, flagella or pseudopods. 78) Pseudopods can be used...
True or False 1) Specific Gravity of wood depends on cell size, cell wall thickness, and the number and types of cells. 2) The thermal conductivity of wood is only a fraction of that of most insulation materials. 3) Water inside cell cavities of wood does not affect shrinkage.
True or False. Some prokaryotes can exist as groups of two or more cells and are giants that actually dwarf most eukaryotic cells. True O False
True/False 0 Indicate whether the statement is true or false. i) Explain your choice in one or to sentences.(6 points) 1. Animals are eukaryotic but plants are prokaryotic. 2. If an organism is multicellular, it is an indication that it is also eukaryotic. 3. In the cell fractionation from the buccal mucosal cells, chloroplasts will precipitate in the same fraction as the mitochondria (This is a trick question, read carefully.)
Which of the following statements is true? a.All cells have a cell wall for protection and structure. b.Eukaryotic cells in plants and fungi, and all prokaryotes, have a cell wall. c.There is a second membrane composed of structural carbohydrates surrounding all cells. d.Prokaryotes and all cells of eukaryotic animals have a cell wall.
True or False: Hydrogen fuel cells emit only water and no carbon dioxide so all fuel cell applications can be considered to be a carbon neutral energy source.
