Cell Biology (CP8121) Experiment 2: Observing Mitosis and Meiosis on cell specimens (Formal report) Name: Wong Chung An Class: DMLS/FT/1B/02 Admin number: P1138687 Summary This experiment aims to observe mitosis and meiosis on cell specimens. It involves the modelling of the stages of meiosis and also the staining procedures to identify mitosis in onion root tip. There are two parts to the procedure of the experiment whereby the first is staining and observing mitosis in onion root tips and the

AP Biology: Chapter 13 - Meiosis and Sexual Life Cycles Overview * The transmission of traits from one generation to the next is called inheritance‚ or heredity * Along with inherited similarity there is also variation * Genetics is the scientific study of heredity and hereditary variation I. 13.1 Offspring Acquire Genes from Parents By Inheriting Chromosomes A. Inheritance of Genes * Parents endow their offspring with coded information in the form of hereditary units

centromere. Chromatin: DNA + Protein. DNA and associated proteins in the nucleus. Chromosome: Genetic material of cell (genome). It is made out of chromatin. Chromatid: Half of a duplicated chromosome. One of two identical attached copies of a replicated chromosome. Centromere: A small region of a chromosome where sister chromatids attach to each other. Important for mitosis and meiosis. The relationship is that each chromosome consists of chromatin. Once replicated‚ a chromosome consists of two

Mitosis in Plant and Animal Cells OBJECTIVES Observe and identify cells undergoing the process of mitosis. Compare the stages of mitosis in plant cells with these stages in animal cells. MATERIALS • compound light microscope • prepared slides (longitudinal sections of onion or garlic root tips) • prepared slides (whitefish blastula or other animal tissue) Procedure PART 1: MITOSIS IN PLANT CELLS 1. Observe a prepared slide of a longitudinal section of onion or garlic root tips. Use low

USE OF ONION ROOT TIPS FOR MITOTIC DIVISION OBSERVATIONS Introduction The zone of cell division on the onion root tip is a great place to observe mitotic cell divisions. Through the observation and comparison of different regions of the root tip‚ the duration of mitotic stages and mitotic indexes are determined for the various divisions of the root tip. Methods Each group used a compound microscope to analyze the different sections of the onion root tip. The root tip was visually

question of the investigation is if lectin can induce mitosis in the cell of an onion root tip. The hypothesis is that‚ if the lectin does not induce mitosis‚ then there should not be a great change in the number of cells that undergo mitosis. The alternate is‚ if the lectin does induce mitosis‚ then there should be an increase in of cells in mitosis. The control group of the experiment had root tip treated with water‚ and the experimental had root tip treated with lectin. Upon the chi-square analysis

Normal cell division meiosis and gamete production via meiosis. Explain why the process of mitosis and meiosis are both important to a living organism. When would an organism need to undergo the process of mitosis? Meiosis? What would happen if meiosis did not occur? Mitosis is the cell process of growth and division whereas meiosis is the process of developing reproductive cells. The sperm and egg are critical components for almost all living organisms. Every living organism begins with one
