The Building Blocks of Life Worksheet Part 1: Mitosis and Meiosis Short-Answer Response Why are the process of mitosis and meiosis both important to a living organism? The process of mitosis and meiosis are both important to a living organism because without them a cell would not be able to reproduce. Mitosis is an asexual process used to replace old and dead cells with new ones by dividing into two identical daughter cells. Meiosis‚ however‚ is the step that makes sexual reproduction possible

1a Using well labelled diagrams create 2‚ 2 fold leaflets outlining the stages of Mitosis and Meiosis. You need to create one leaflet for each (P2). 1b Using well labelled diagrams explain how the behaviour of chromosomes during meiosis leads to variation. In this report you must explain crossing over and independent assortment (P4). (Max 500 words) 1c Create a table comparing mitosis and meiosis (P2). Task 2 2 Carry out practical investigations to record stages of cell division

Meiosis 1. What does it mean when two sets of chromosomes are homologous? It means that each of the four chromosomes that come from the male parent has a corresponding chromosomes from the female parent. 2. Highlight the letter of each way to describe a diploid cell. a. 2N b. Contains two sets of homologous chromosomes c. Contains a single set of homologous chromosomes d. A gamete 3. Highlight the letter of the number of chromosomes in a haploid cell where 2n=8 . a. 8 b. 4 c. 2 d. 0

the cell cycle lasts longer than mitosis? A) TRUE - A cell spends about 90% of its life in interphase of the cell cycle‚ while it spends only about 10% of its life in M phase. 3. When does DNA replication occur in the cell cycle? A) Interphase 4. Which statement about the cell cycle is incorrect? C) In G2 phase M the cell begins shrinking in preparation for division. 5. Identifiable chromosomes are present in the cell only during…. D) M 8.1.2 Mitosis: an overview 1. Which statement

Kristian Gelfo 1. List and describe the phases of Meiosis 1. A: Metaphase I - Paired homologues move to the center of equator of the cell. Anaphase I - The homologues seperate from each other and get moved to opposite poles by kinteochores. Telophase I - Spindle microtubules dissappear‚ cytokinesis occurs‚ and the nuclear envelope reappears. 2. Describe homologue pairing and crosing over. At which stage of meiosis do they occur? A: When two homologous chromosomes come together before
