Pouri‚ Nikole Period 1 1/14/12 Mitosis Lab Write-Up Purpose: The purpose of this lab is to understand the phases of mitosis through a hands on experience and not just textbook information. The objective is to visually determine each phase through a microscope with a clear understanding of what is happening. With this knowledge and this visual a picture is to be drawn as descriptive as possible for each phase. Materials: The materials needed are; 1) Microscope 2) A slide containing plant

BIO Microscopy‚ Mitosis‚ and Motility Lab Discussion Questions In the Microscopy‚ Mitosis‚ and Motility lab‚ the class used the Compound Microscope. The Compound Microscope helped examine the prokaryotic and eukaryotic cells‚ observe the different stages of mitosis‚ and compare modes of motility used by protists. The light compound microscope works with the aid of lenses such as the eyepiece. These lenses help keep the focus of the light on the eye. The fine and course adjustments also assist with

Mitosis Under Microscope Lab Report A. The purpose of the investigation is to determine the time an onion cell spends in each part of the cell cycle. B. The significance of this investigation is to help us understand and know how long cells are undergoing mitosis. My personal interest is to know the phases of mitosis in cells in order to someday help find cures for cancer. C. The cell cycle is a chronological set of events‚ culminating in cell growth and division into two daughter cells. Some

Complete the following questions and submit via Blackboard 1. List two events which occur during prophase of mitosis: 1. An aster is formed by fibers radiating from the centrioles of the cell. 2. Chromosomes are formed when the chromatin threads coil and then condense‚ and these chromosomes are two identical chromatids bound together by a centromere. 2. What is the main occurrence involving the chromosomes during

Mitosis Lab Mitosis in Onion Root Tips Make a sketch of a representative cell in each of the four stages of mitosis in the space provided below. Prophase Metaphase Anaphase Telophase Can you distinguish any cells? Yes‚ you can identify cells that are undergoing development. In prophase‚ the chromosomes make and x shape. In metaphase‚ the chromosomes are moved to the middle of the cell. In anaphase‚ the chromosomes look like they are being pulled apart. And in telophase‚ the cell starts

Lab 3: Mitosis and Meiosis Purpose: The purpose of this lab was to recognize the stages as well as events of mitosis and meiosis in a plant cell or an animal cell. The relative duration of each stage in the cell cycle will also be learned during this lab. By doing this lab we will also create a model of and understand the process of crossing over. This lab also helps students understand the similarities along with differences between mitosis and meiosis. Hypothesis: I predict that

Mitosis in a Nutshell • The stages of the cell cycle can be broken down into six stages: o Interphase‚ Prophase‚ Metaphase‚ Anaphase‚ Telophase Interphase • Is the "resting" or non-mitotic portion of the cell cycle. • It is comprised of G1‚ S‚ and G2 stages of the cell cycle. • DNA is replicated during the S phase of Interphase Prophase - the first stage of mitosis. • The chromosomes condense and become visible • The centrioles form and move toward opposite ends of the cell ("the poles")

MITOSIS The Stages of Mitosis Mitosis is simply described as having four stages—prophase‚ metaphase‚ anaphase‚ and telophase; the steps follow one another without interruption. The entire four-stage division process averages about one hour in duration‚ and the period between cell divisions‚ called interphase or interkinesis‚ varies greatly but is considerably longer. During INTERPHASE the chromosomes are dispersed in the nucleus and appear as a network of long‚ thin threads or filaments‚ called the

Mitosis Mitosis is the process where a cell divides‚ to create two diploid cells identical to the first other than for a small bit of protein that lets the cell know how many times it has divided. 1. The cell duplicates its chromosomes so that it now has double as many‚ but they remain attached. 2/3. The cell begins to split until it has the chromosomes have separated completely‚ to form two separate set of chromosomes. The cell begins to divide. 4. The cell divides completely to form two diploids

copy their genetic material. Mitosis is the first stage of cell division‚ in which the copied chromosomes are separated into two new nuclei. Then in cytokinesis the cell divides into two daughter cells. If no mutations or errors occur‚ the genetic material in each daughter cell is identical to what was in the original cell. Now that you have completed this lesson‚ you should be able to: describe the stages of the cell cycle explain the process of mitosis and its role in the formation
