  1. Describe the relationship between what is actually seen on the microscope slide and the orientation of the image viewed through the microscope.
    It's the opposite.
  2. Describe the consequences when moving from scanning, to low, and to high power.
    Increased magnification, narrowing of depth of field
  3. Describe the meaning of the term parfocal.
    Increase in magnification power does not change of the position of the specimen.
  4. nucleus
    Houses the genetic code, which dictates protein synthesis, playing an essential role in other cell activities such as cell transport, metabolism, and growth.
  5. cell (plasma) membrane
    Serves as the boundary of the cell, maintains its integrity; protein molecules embedded in membrane perform various functions.
  6. cytoplasm
    Gelatinous substance made up of organized subunits called organelles.
  7. nucleolus
    Part of the nucleus; plays an essential role in the formation of ribosomes.
  8. chromatin
    Threadlike form of DNA, makes up the genetic material of the nucleus
  9. microvilli
    Border made up of epithelial cells in the small intestine; increases the surface area for the absorption of nutrients.
  10. cilia
    Hairlike projections of cells
  11. flagellum
    Single projection extending from the cell surface, similar to a cilium, only example in humans is the "tail" of the male sperm.
  12. organelle
    any of the many cell "organs" such as mitochondrion or ribosomes
  13. ribosome
    Organelle in the cytoplasm of cells that synthesizes protein; sometimes called a "protein factory"
  14. rough endoplasmic reticulum
    An organelle that forms a network of tubules and vesicles within a cell (contains ribosomes)
  15. smooth endoplasmic reticulum
    Region of endoplasmic reticulum system that does not contain ribosomes
  16. Golgi apparatus
    Organelle consisting of small sacks stacked on one another near the nucleus that makes carbohydrate compounds, combines them with protein molecules and packages them for distribution throughout the cell.
  17. lysosome
    Membranous organelle containing enzymes that can dissolve most cellular compounds, also known as the digestive bags of the cell.
  18. peroxisome
    Organelles that detoxify harmful substances that have entered the cell
  19. mitochondria
    Organelle in which ATP generation occurs; often called the "powerhouse" of the cell
  20. centriole
    One of a pair of tiny cylinders in the centrosome of a cell; believed to be involved with the spindle fibers formed during mitosis
  21. microtubule
    Component of the cell's cytoskeleton, provides cell structure; also involved in intracellular transport.
  22. microfilament
    Tough, flexible filaments that provide support and structure to the cell; also involved in cell mobility.
