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:
Step by step

- Which of the following options correctly describes the functions of both cilia and flagella? Excretion Protection Locomotion Body’s defense BENTEN: During meiosis I, pairs of homologous chromosomes align randomly along the metaphase plate before being separated. This process helps generate genetic variation in the offspring of sexual reproduction. Which of the following best explains how the random alignment of homologous chromosomes during meiosis helps generate varied offspring? Random alignment increases the likelihood of crossing over between non-sister chromatids. Random alignment results in the formation of gametes that contain different numbers of chromosomes. Random alignment increases the number of possible chromosome combinations in the gametes. Random alignment results in the formation of some diploid and some haploid gametes.Which of the following is true regarding kinesin 4? O it is located on chromosomes that are not attached to microtubules O it is found on microtubules near the plasma membrane it is located on the microtubules at the centrioles O it is located at the DNA kinetochore O it is located on the tips of DNA chromosomes and attach to polar microtubulesThe cells bellow are in the process and stages as indicated. Each cell has a 2n # of 6. In the cells below show all of the chromosomes and their proper location and draw and label the metaphase plate, kinetochore, spindle, centrosomes, homologous chromosomes, microtubules, DNA, sister chromatids, centromere MITOSIS (Metaphase) Total number of chromosomes Total number of homologous pairs of chromosomes MEIOSIS (Metaphase I)

- the light micrograph shows dividing cells near the tip of an onion root. identify and encircle a cell in each of the following stages: phrophase , prometaphase, metaphase ,anaphase and telophase. describe the major events occuring at each stage.The centromeric connections between chromatids fail to be severed. Kinetochores from sister chromatids become attached to microtubules from the same pole. A motor protein at the kinetochore is not functional. The chromosomes fail to attach to the kinetochore microtubules. Chromosomes will not move to the metaphase plate. Chromatids will not separate during anaphase. One kinetochore will detach from the spindle. Chromosomes will not move toward centrosome during prometaphase.The crawling displayed by many embryonic cells in animals involves distinct events. Which of the following sequences places these events in correct order? protrusion at the cell's leading edge, attachment of protrusion, pulling the cell forward, release and retraction of trailing edge attachment of protrusion, pulling the cell forward, protrusion at the cell's leading edge, release and retraction of trailing edge release and retraction of protrusion, protrusion at the cell's leading edge, attachment of trailing edge, pulling the cell forward pulling the cell forward, release and retraction of protrusion, protrusion at the cell's leading edge, attachment of trailing edge attachment of protrusion, protrusion at the cell's leading edge, pulling the cell forward, release and retraction of trailing edge
- Which of the following would best describe the result of a developing insect embryo that was mechanically agitated in order to evenly redistribute cytoplasmic determinants throughout the embryo?
