explain how IPMAT (INDIVIDUALLY) involves Cell division/ mitosis and meiosis
Prophase::chromosomes condense and become visible
spindle fibres emerge from the centromeres
nuclear envelope break down and nucleolus disappears
Metaphase
Mitotic spindle is fully developed,centrosomes are at opposite poles of the cell
chromosomes are lined up at the metaphase plate
Each sister chromatic is attached to spindle fibre originating from opposite poles
Anaphase
Cohesin proteins binding the sister chromatids together break down
sister chronatids are pulled towards opposite side
Telophase
chromosomes arrive at opposite poles and begin to condense
The mitotic spindle breaks down
explain how IPMAT (INDIVIDUALLY) involves Cell division/ mitosis and meiosis
Match the following statements/functions with the appropriate type of cell division: Gamete production: meiosis/mitosis Reduction of ploidy from diploid to haploid: meiosis/mitosis Generation of genetic variation : meiosis/mitosis Production of clones : meiosis/mitosis Organism growth and development: meiosis/mitosis Tissue renewal: meiosis/mitosis Potential survival of the species in a changing environment: meiosis/mitosis Asexual reproduction: meiosis/mitosis Sexual reproduction: meiosis/mitosis
The cell division depicted here is Mitosis only Meiosis only Binary fission All of the above None of the above The cell type is Animal Plant Bacterium All of the above None of the above What phase of cell division is the cell at? Anaphase Interphase Metaphase Prophase Telophase How many chromosomes each of the daughter cells will have at the end of cell division? 3 6 9 12 None of the above
When does DNA replication occur in the cell cycle? mitosis cytokinesis O meiosis both mitosis and meiosis sphase of interphase A hermaphroditic worm would create gametes with what type of cell division? mitosis none of these synapsis O meiosis
Compare mitosis and meiosis by filling in the chart below. Meiosis Mitosis Characteristic Are daughter cells genetically identical or different from the parent? Involves how many cell divisions? Produces how many daughter cells? Produces haploid or diploid cells? Produces what type of cell? Sister chromatids or homologous chromosomes separate? What are the functions of the cells produced? 05 Answer the following Explain how segregation of chromosomes during meiosis can generate four types of gametes (assume four chromosomes, two homologous pairs)...
What begins with a haploid cell? Mitosis, Meiosis, Neither mitosis or meiosis, or both mitosis and meiosis. Biology.
Which of the following statements is correct? Meiosis involves one division and produces two nonidentical daughter nuclei. Mitosis involves two divisions and produces four identical daughter nuclei. Mitosis involves one division and produces two nonidentical daughter nuclei. Meiosis involves two divisions and produces four nonidentical daughter nuclei.
How do the results of meiosis and mitosis differ in terms of chromosome numbers? Fill in the diagrams with the appropriate chromosome number (total number of chromosomes and/or sister chromatids!) by assuming that each original cell (at the top of the diagram) represents a human cell with a diploid number of chromosomes in G2 stage of the cell cycle. mitosis meiosis O first meiotic division first meiotic division 2nd meiotic division O OO O
2.Know the mitosis and meiosis cell cycles in complete detail. This includes the names of the stages and what happens to the chromosomes during each stage. What kinds of cells does each process produce? Which is the ‘reduction division’ and what does this mean? How many cell divisions are in each cell cycle? Know when chromatids separate in meiosis. Do they separate in mitosis and if so when does this happen?
1) Are ascospores produced by meiosis or mitosis? Explain your reasoning 2) Describe first division and second division segregation.
