  • What makes something a eukaryote?
    1) Nucleus 2) Membrane bound organelles
  • a cell that contains DNA and cytoplasm is a _____________
    prokaryotic cell
  • Are protists unicellular, multicellular, or both?
    Both!
  • True or False: All fungi are eukaryotes.
    True
  • True or False: Fungus-like protist use spores to reproduce.
    True
  • Virus are made up of what?
    Genetic material
  • Is bacteria smaller than a cell?
    Yes, they are.
  • What are the three environments we find protists in?
    1) Water 2) Soil 3) Animals
  • True or False: All fungi are heterotrophs that feed by absorbing their food.
    True
  • Why is the classification of protists in one kingdom so difficult?
    They resemble members of other kingdoms.
  • Are viruses surrounded by a protein coat?
    Yes, they are.
  • True or False: Bacteria live in most habitats
    True
  • A protist which has the ability to alter its shape, primarily by extending and retracting pseudopods.
    amoeba
  • Are fungi eukaryotes or prokaryotes?
    Eukaryotes
  • Give some examples of places where archaea can be found
    Hot springs, extremely acidic habitats, extremely salty habitats, near deep-sea vents, 8km below the earth's surface
  • How do virus get their name usually?
    they are named after a disease or the person who discovered them
  • What is chitin?
    Chitin makes up the cell walls of fungi
  • A heterotrophic eukaryote with cell walls that contain chitin. Includes molds and mushrooms.
    fungi
  • True or False: Plant-like and fungus-like protists like wet surroundings, but animal-like protists do NOT like wet surroundings.
    False
  • When a virus enters a bacterial cell, makes copies of itself and causes the cell to burst or lyse, it is in the _____________ cycle.
    Lytic
  • Bacteria can move. What is the name of the structure that moves them?
    Flagellum
  • Do fungi reproduce sexually or asexually or both?
    Both!
  • Why do some scientists believe that viruses are not living organisms?
    Because viruses do not respond to their environment, have no metabolism, and cannot replicate on their own.
  • A cytoplasmic projection from the organism that extends to allow the organism to move. Latin for "false foot"
    pseudopod
  • What do virus' need to reproduce?
    A host
  • Are bacteria unicellular organisms?
    Yes
  • Virus contain ___________ and __________.
    Protein coat and genetic material
  • Why are virus considered non-living?
    Viruses don't need nutrients/food and do not reproduce on their own. They need a host cell.
  • What is a plant-like protist that has beautiful glasslike cell walls and unusual shapes
    Diatoms
  • A protist and fungus reproductive cell.
    spore
  • Are protists eukaryotes or prokaryotes?
    Eukaryotes!
  • Protists that live mostly in water and use sunlight as a source of energy.
    algae
  • Virus are living or non-living particles?
    non-living
  • do archaea only live in extreme environments?
    No, archaea are everywhere
  • What are plant-like protists also known as?
    Algae
  • What is a plant-like protist that has a pigment that is good at absorbing small amount of sunlight in deep ocean water?
    Red Algae
  • How do bacteria reproduce?
    By binary fission
  • Why don's doctors give antibiotics for viral infection?
    Antibiotics only kill bacteria ,they do not work on virus
  • Autotrophic protists provide what important element through photosynthesis?
    Oxygen
  • True or False: Fungi use seeds to reproduce.
    False
  • What happens in the lytic cycle?
    The lytic cycle produces new viruses and breaks open the host’s cell wall, releasing the viruses.
  • What do viruses need to reproduce?
    host cell
  • can prokaryotes get energy, reproduce, and/or move?
    Yes, they can
  • Describe host range.
    Each virus has a limited number of host cells that it can infect.
  • True or false: Can bacteria be both harmful and helpful? Give one example of helpful bacteria.
    True. Ex of helpful bacteria: the ones in the cheese, yogurt, in our stomach, intestine
  • Do fungi preform photosynthesis?
    No! They are heterotrophs and do not use the sunlight to create energy.
  • word means "to break down"
    lytic
  • What are TWO characteristics of animal-like protists?
    They can move and heterotrophs
  • What is a plant-like protist that has the same pigment as land plants
    Green Algae
  • Long, branching filaments made of cells. These compose the bodies of fungi.
    hyphae
  • What do mycorrhizea fungi do?
    Extend the root network of plants in order to help plants find water and nutrients in the soil
  • What is a plant-like protist that can be many colors and has plant-like structures such as roots, stalks, an leaves.
    Brown Algae
  • Little hair-like projections that move cells like oars on a rowboat.
    cilia
  • What are TWO characteristics of plant-like protist?
    Autotrophs and exist in a wide variety of colors or pigments
  • Are bacteria living things?
    Yes, they are
  • Are protists heterotrophs, autotrophs, or both?
    Both!
  • Do protists reproduce sexually or asexually or both?
    Both!
  • how are archaea and bacteria different?
    both are prokaryotes but genetically very different, each has unique chemicals in their cell walls
  • Where do archaea often live?
    Archaea often live where nothing else can.
  • Are fungi heterotrophs, autotrophs, or both?
    Heterotrophs!
  • What do flagella, cilia, and pseudopods have in common?
    They aid in protists locomotion
  • These contain a dead form of a virus and give immunity to it?
    Vaccines

    Both!
  • A hard substance that strengthens the cell walls of fungi and other organisms.
    chitin
  • How do bacteria reproduce?
    Binary Fission
