Microorganisms
Volvox

  1. Found in ponds

  2. Member of a group called green algae

  3. No roots, stems, or leaves

  4. Uses light to make food

  5. Live in water or damp surfaces

  6. Cells live in colonies of 1,000 to 3,000 cells arranged in a hollow sphere

  7. Each one has two flagella—a whiplike tail that helps them move

  8. The colony is held together by a clear jellylike substance

  9. Some large colonies contain daughter colonies; these are released from the parent when they become big enough

  10. Benefit of living in a colony—protected from outside predators that are larger

  11. It is a BRIGHT GREEN


Blepharisma

  1. Found in ponds

  2. Single-celled and pear-shaped

  3. About 160 micrometers

  4. Rosy colored

  5. It eats bacteria & other microbes; sometimes they eat each other=cannibals

  6. Belongs to a group called ciliates=body is covered with short, moveable, hairlike extensions called cilia which act like paddles to move

  7. Reproduces by dividing itself in half to produce 2 equal halves; this is called binary fission


Vinegar Eels

  1. a harmless roundworm about 1.5 to 2 mm long with points at both ends

  2. smooth, slender, almost transparent body

  3. Made up of many cells

  4. Large enough to be seen without a microscope

  5. One of the lowest animals to have a digestive system

  6. The embryos develop in the female and are born alive and wiggling

  7. Can live in a very acidic environment

  8. Live in unpasteurized cider vinegar

  9. Eat bacteria and apple

  10. Pasteurization is a process of heating a liquid at a high temperature to destroy microbes and produce a sterilized liquid

  11. Whole body has muscles that help them move very rapidly



Topics to study for the

Microworlds Test


  • Microorganisms (Volvox, Blepharisma, & Vinegar Eels)

  • Two properties of Magnifiers (transparent & curved

  • Be able to draw a convex lens

  • Definitions

    • Magnification- how many times something is made to look bigger compared to its real size

    • Transparent-clear; it can be seen through

    • Convex-curved outwardly

    • Nucleus-the control center of a cell

    • Cell wall-found only in plant cells; protects the cells

    • Observations- Information that you gather by using your five senses

    • Protoplasm-clear liquid inside a cell

    • Inference-a conclusion based on observation

    • Cell-the smallest whole parts of living things

    • Cilia-short, movable, hair-like extensions that act like paddles to move

    • Properties-observable characteristics of an object

    • Microscope-instrument with a lens or lenses used to make objects look bigger

    • Bacteria

    • Blepharisma

    • Volvox

    • Vinegar eel
