- A section of elodea leaf is stained and examined under a microscope. The total number of cells in each stage of the cell cycle is as follows: Interphase- 150 Prophase- 20 Prometaphase- 11 Metaphase- 6 Anaphase- 5 Telophase- 1 If the complete cell cycle in an elodea leaf is 24 hrs. What is the average duration of metaphase in the cycle. Assume no cells are in G0.Count 100 cells and tally them. Remember the phases you learned in Bio 31 and Anatomy? Draw a pie chart graph showing the phases of Allium root tip. Label each of the phases with the % for each phase: prophase metaphase anaphase telophase interphase provide direction of the phase progression--direction in which to read the graph so the phases of mitosis are in proper order.If plant cells had the following % of their cells in these stages of mitotic cell division and % of cells reflects how much time they spend in each stage: Interphase=74.9% Prophase=17.3% Metaphase=3.3% Anaphase=D1.8% Telophase=D2.7% and Animals had the following %s: Interphase3D62.5% Prophase-D31.5% Metaphase=3.3% Anaphase=D2.0% Telophase%3D0.7%. Which of the following can we NOT conclude? O A. Both plants and animal cells spend most of their time in interphase, doubling all of the organelles and DNA requires a lot of time. OB.Animal cells spend more of their time in mitosis (dividing the nucleus) than plant cells do. O C. Plant cells spend more time in interphase and telophase than animal cells and animal cells spend more time in prophase, and anaphase than plant cells. OD. Plant cells divide more quickly than animal cells.

- 0200 7 The anticancer drug paclitaxel (Taxol), derived from the Pacific Yew, has many effects on mitosis. One of its most powerful effects is that it prevents disassembly of the mitotic spindle, which prevents spindle fibers from shortening. Which phase of mitosis would this directly affect? Why would this stop cell division overall and lead to cell death? LANDY సిగోలుకుం చగన 40 92800Consider the proper progression of the cell cycle.
