Meiosis And Meiosis: The Four Progressive Stages Of Cell Division

Decent Essays
Meiosis and mitosis are the processes used by cells to divide and replicate. Although similar in function, division by mitosis is strictly asexual and can occur in any cell in the body. Meiosis reproduction however, occurs exclusively in reproductive cells.
Meiosis has two major stages in which cell division will occur: meiosis 1 and meiosis 2. Both meiosis 1 and 2 have four progressive stages: prophase 1 and 2, metaphase 1 and 2, anaphase 1 and 2, and telophase 1 and 2. During prophase 1 homologous chromosomes pair up tightly with one another, the exchange or “crossing” over of genetic information will occur at this stage. Metaphase 1 involves the spindle fibers attaching to the chromosomes and lining them up down the center of the cell.

    Purpose and Background Cells divide in two ways, mitosis and meiosis. Mitosis is used to produce cells that are genetically identical to the parent cell for growth, asexual reproduction, or repair after injury. Cells that are produced by mitosis are diploid, meaning that they have two complete sets of chromosomes, one from each parent. Meiosis is used to produce haploid cells that have only one set of chromosomes, a mix of chromosomes from both parents. Meiosis produces cells that are genetically unique from their parent cells.…

    Inside the ovary there are ovules that contain megasporangium (2n) that produce megasporocytes (2n) that can undergo meiosis to produce four megaspores (n). Only one of the megaspores survives, remaining inside the ovule. Integuments surround the ovule closing off nearly all of the ovule except a small opening, known as the micropyle. The process creates the female gametophyte, the embryo sac, which among other things contains an egg and two polar nuclei. Wind or pollinators causes the pollen grain to land on the stigma where it forms the pollen tube which allows the two sperm to travel into the embryo sac.…

    Mitosis: I take the two identical sister chromatids in each chromosome and divide them to form two new cells with one chromaid each. The original cell is the parent cell that divides to produce the four new daughter cells. The new cells are called haploids which means that they have one set of chromosomes whereas the parent cell is a diploid and has two, one from each parent. One important part is cytokenesis which makes sure that I have a nucleus in each new daughter cell.…

    Meiosis starts: DNA Replicates I am going to draw a nucleus with DNA inside it represented with beads as the four pairs of chromosomes. Outside of the nucleus there will be centrioles drawn. This is where meiosis begins and replicates the cell Spindle fibers start to form on the centrioles and chromosome pairs bind together making tetrads. Nuclear membrane starts to dissolve.…

    Mitosis is similar to binary fission in terms of results, chromosomes are replicated, copies are moved. The opposite ends of the parent cells separate giving rise to 2 daughter cells that are similar to the parent cell. Mitosis is the type of cell division that replicates gametes. It lowers the number of chromosomes by ½. When sperm fertilizes then it has full set of chromosomes.…

    Telophase/cytokinesis occurs when there is no longer a mother/father pair together, After the completion of meiosis I, the cells are no longer diploid cells, but rather haploid cells. Meiosis II also has four phases including prophase II, metaphase II, anaphase II, and telophase II/ cytokinesis. Prophase II occurs when spindle fibers reform and attach to the centromeres. Metaphase II consist of the chromosomes lining up to prepare for the division of centromeres in the next phase.…

    During metaphase, mitotic spindles move to the opposite poles. Then the chromosomes are pulled by the kinetochore microtubules at the metaphase plate. Sister chromatids are still attach to the kinetochore microtubules. In anaphase, two sister chromatids are separated, and become full-fledged chromosomes. The separated daughter chromosomes…

    Then the final part of Interphase is G2, which is where the Mitochondria and chloroplasts in the beta cell divide and the beta cell prepares for Mitosis to start. After interphase the cell begins to start mitosis, this is where the cell divides in order to produce two genetically identical cells using one parent cell. There are four stages of mitosis: prophase, metaphase, anaphase and telophase. All four stages are vital for the beta cell when going through the cell…

    1.1 Describe stages of development from conception to birth. When an egg is fertilised it is a single cell called a Zygote, in the next 24-36 hours the single cell will divide into two cells, 12 hours after it will divide into four cells, and will carry on dividing which forms a cluster of cells which are called a monula. Three – four days after it has been fertilised the monula will move from the fallopian tube and will enter the uterus. At about six days the monula will form a hollow cavity which is known as a blastocyst. The blastocyst will burrow itself into the uterus lining this is called implantation.…

    Cell division is a complex biological method in which a parent cell divides into two or more daughter cells, depending on whether or not that division is mitosis or meiosis. For simple one-cell organisms, like amoebas, archaea and protozoa, single cell division, mitosis, is akin to reproduction. For multicellular organisms, meiosis produces four haploid daughter cells by undertaking a single round of DNA replication, shadowed by two more cellular divisions. In all, the principal purpose of cell division is the preservation and replication of the original cell 's genome, regardless of whether that cell division is through mitosis or meiosis. Before cellular division can begin, the genetic information that is stored in the gene’s chromosomes…
