Mitosis

 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...

Mitosis

MITOSIS What is Mitosis? There are various structures within the cell, but many are too difficult to see. For example, within the nucleus lie the chromosomes. These are important for heredity and reproduction. When a cell splits and becomes two, certain processes occur within the nucleus first. One of these processes involves the splitting of the chromosomes. This process is called Mitosis and there are four distinct stages. Mitosis takes place in Regular Body Cells or Somatic Cell. It keeps...

Mitosis

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

Mitosis is the process in which a cell breaks apart its chromosome to eventually produce two identical daughter cells. The cell spends 10% of its time in mitosis. The cell goes through four stages in order to complete this task. The stages are Prophase, Metaphase, Anaphase and Telophase. Mitosis only occurs in eukaryotic cells and the process is different for different species. Mitosis is fast and very complex. The first phase is Prophase. In prophase, the chromosomes the chromosomes start to...

mitosis

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...

Mitosis lab

Title- Mitosis Abstract –For this lab there is no experiment to be done only questions to be answered. In this experiment we will categorize and count the cells to compute the mitotic index of the total root area. Introduction – The purpose of this experiment is to answer questions associated with the onion root tip photos that are pictured in the lab. The questions for this lab will be drawn from the discussion and review section at the beginning of the mitosis lab. Once that section has been...

Observation of Mitosis

Observation of Mitosis Introduction: Reproduction is the biological process by which new individual organisms are produced. There are two types of reproduction, which are; asexual and sexual reproduction. Asexual reproduction is creation of offspring whose genes all come from one parent. Sexual reproduction is creation of offspring by fusion of male gametes (sperm) and female gametes (eggs) to form zygotes. Asexual reproduction involves a type of cell division known as mitosis. Mitosis is the scientific...

Mitosis & Meiosis

Mitosis & Meiosis In science class this week, we've been learning about cell reproduction. What is Cell division? What is Mitosis? What is Meiosis? How are they alike? How do they differ? All of these amazing questions will be answered, if you decide to read on. The Cell Cycle A life cycle begins with an organism’s formation, followed by its growth and development, and the production of offspring that will repeat the cycle, before ending in death. Right now, I am in a stage in the life...
