Is the person in the karyotype below male or female? How can you tell?<\/h3>\n

Mitosis:<\/h2>\n

Mitosis – video animation of the process<\/a>\u00a0– try and narrate this yourself. Important stages to understand and identify are interphase, prophase, metaphase, anaphase, telophase. (1:22)<\/p>\n

Mitosis Rap<\/a>\u00a0– a nice annimation and explanation of mitosis, a little more detailed that what you need for lab, but may be helpful for lecture and greater understanding of the mechanics. (3:17)<\/p>\n

Mitosis animation<\/a>\u00a0– to view on your own as review (6:10)<\/p>\n

Onion Root Tip Cell Cycle – identify the stages you can see below and determine the cell cycle in lab using prepared slides.<\/p>\n

\"Stained\u00a0<\/a>\"Onion<\/a><\/p>\n

 <\/p>\n

The pie chart below was generated from a random sampling of cells in the onion root tip.\u00a0 Answer the following questions:<\/h3>\n
    \n
  1. Based on the graph below, what can you tell about this region of the onion root tip?<\/li>\n
  2. Why are some phases of the cell cycle larger than others?<\/li>\n
  3. Why is Interphase so much different from the stages of mitosis? What occurs during interphase?<\/li>\n
  4. Why are some stages of mitosis larger than other stages of mitosis?<\/li>\n
  5. How would these results be different in other areas of the plant? Why would they be different?<\/li>\n<\/ol>\n

    Lily Anthers will produce cells that will eventually become pollen.\u00a0 Meiotic cells at lower magnification so you can still see the cross section of the anther.<\/h3>\n

    \"lily<\/a><\/p>\n

    Meiotic cells at higher magnification within the anther locuoles (below).<\/h3>\n

    Can you identify the stages you can see below as either in Meiosis I or II?<\/p>\n

    You may be able to identify a few cells in PI, MI, AI, TI, PII, MII, AII, TII<\/p>\n

    Meiotic cells under higher magnification (below). Not all stages are present NOR are they in any particular order.<\/h3>\n

    In what order would you put them?<\/p>\n
