Oogenesis
The formation of the ovum (mature female gamete) from undifferentiated germ cells is called oogenesis. This process takes place in the ovaries (female gonads). Oogenesis consists of three stages known as the multiplication phase, growth phase, and maturation phase.
Cell Division
Cell division involves the formation of new daughter cells from the parent cells. It is a part of the cell cycle that takes place in both prokaryotic and eukaryotic organisms. Cell division is required for three main reasons:

- Diagram metaphase and anaphase of mitosis, meiosis I and meiosis II in a cell containing two different chromosome types (2n=4). Label the spindle fibers, homologous chromosomes, and sister chromatids. Count the total number of chromatids present at each stage.In Coleus , the somatic cells are diploid with 24 chromosomes. How many of each of the following is present in each cell at the stage of mitosis and meiosis indicated below? kinetochore at prophase chromosomes at anaphase chromatids at metaphase 1 chromosomes at telophase after cytokinesis centromeres at anaphase chromosomes at telophase II after cytokinesis centromere at anaphase I chromatids at metaphaseList three ways in which mitosis differs from meiosos. Be specific
- Can be more than one answer: Select all of the following that are true of MEIOSIS but not of MITOSIS. a) cell division occurs during cytokinesis b) results in two identical daughter cells c) halves the number of chromosomes in a cell d) spindle fibers contract during anaphase e) tetrads line up on metaphase plate+ 1. Complete the table below for chromosome and chromatid number for a human cell: Mitosis Prophase Metaphase Anaphase Telophase End of Mitosis Meiosis I Prophase Metaphase Anaphase Telophase End of Meiosis I Meiosis II Prophase Metaphase Anaphase Telophase End of Meiosis II Chromosome Number Chromatid NumberList in each blank the description of events associated with each stage of mitosis in addition to the preparatory stage Interphase. Some events and structures occur only in plant cells and some in animal cells. Mark these events in the list with an asterisk.
- Imagine a nucleus that has 10 chromosomes. How many chromosomes does it have before prophase begins? How many chromosomes does each daughter nucleus have after telophase has been completed? How many chromatids are present in the one mother nucleus before prophase begins? How many chromatids are present in each daughter nucleus after telophase has been completed? How many chromatids are present if you add together all chromatids in both daughter nuclei after telophase has been completed?Indicate the stage of mitosis (interphase = I, prophase = P, metaphase = M, anaphase = A, telophase = T) during which each of the following events occur. chromatid doublets separate to individual chromosomescentriole replicatesreplicated chromosomes (chromatid doublets) are arranged in single file next to one another at the cell's equatornuclear membrane is disappearingspindle fibers form and become visiblecell plate (plant) or cleavage furrow (animal) forms and is visiblechromosomes are at opposite poles of the cell; cytokinesis is almost completedchromosomes (chromatids) first become visible as long thin strandsDNA (chromosome) replication occursDraw a single duplicated chromosome, labeling the chromatid(s) and centromere
- For an organism with 3 pairs of chromosomes (6 total chromosomes, 2n = 6), draw chromosome diagrams for the following phases of the mitotic cell cycle: G1 of interphase, prophase, metaphase, anaphase & telophase. Be sure to draw the correct number of chromosomes and the correct number of chromatids per chromosome. Use a different color to represent each chromosome type (for example, use blue to indicate all copies of chromosome 1, red for all copies of chromosome 2, & green for all copies of chromosome 3).Which of the following statements are true regarding mitosis in humans? 23 pairs of homologous chromosomes are separated four haploid gametes are produced in males 46 pairs of homologous chromosomes are separated two genetically identical daughter cells are produced 23 pairs of sister chromatids are separated 46pairs of sister chromatids are separated 1 haploid gamete and 2 polar bodies are produced in femalesMatch the phases of meiosis with the correct description Metaphase I [ Choose ] [Choose ] Sister chromatids line up along the center of the cell. Cytokinesis produces four unique daughter cells, spindle dissolve, and the nuclear envelope reappears. Spindle fibers pull homologous pairs of chromosomes apart. Nuclear envelopes of daughter cells dissolve, and chromosomes condense. Spindle fibers pull sister chromatids apart. Homologous pairs of chromosomes line up at the center of the cell in tetrads. Cytokinesis produces two daughter cells, spindle dissolves, and nuclear envelope reappears. Nuclear envelope dissolves, DNA condenses and crossing over occurs.
