Tell what happens to the number of chromosomes and chromatids during each stage of mitosis and meiosis.

Answer:

Prophase- chromosomes are forming
Metaphase-same number of chromosomes move to center of cell. Metaphase ends when chromosomes split, thus doubling the number of chromosomes.
Anaphase-When the chromosomes split at the end of metaphase, the chromosome number is doubled. Ex) human cell
Phase # of Chromosomes # of Chromotids
Pro 46 92
Meta 46 92
Ana 92 92
Telo 92 92
Telophase-Telophase begins when chromosomes reach the poles of the daughter cells.
Interphase- Non dividing stage
G1- each chrmosome has oen chromotid, cell has grown in size
S-DNA synthesis occurs
G2- each chromosome has two chromatids.

    Describe what happens to the nuclear membrane, spindle apparatus, and centrioles during each phase of mitosis and meiosis? When does cytokinesis occur?

    Thenuclear membranebecomes fragmented and disappears by the end of prophase. In prophase each centrosome of an animal cell contains two centrioles. Plant cells do not have centrioles but they do form spindle fibers.The spindle apparatus is fromed in metaphase. Centrioles are located on each side of the cell, connected to chromosomes by microtubules. In anaphase,polar microtubules push against each other and thus, push the two centrosomes apart. This, in turn, also pulls the chromosomes apart.The chromosomes move toward poles of cell. Many of the events in telophase are the reverse of prophase. The chromosomes uncoil, the nuclear membranes around daughter nuclei appear, the spindle apparatus breaks down, and the nucleolus reappears. Cytokinesis (division of the cytoplasm) begins in anaphase.

    What are the spindle fibers made of?
    The microtubules, also called spindle fibers, form from an area of the cell called the centrosome. During interphase, the cell has one centrosome but just before prophase, the centrosome duplicates, producing a second centrosome. During prophase, microtubules radiate from each centrosome. Some of the microtubules extend from one centrosome toward the other.

    Describe how plant cells differ from animal cells with regard to centrioles and cytokinesis.

    Each centrosome of an animal cell contains two centroioles. Plant cells do not have centrioles but they do form spindle fibers.

    cytokinesis differ from plants cells and animal cells because plantshave cell walls.

    Describe the process of cytokinesis in plant cells.
    Instead of forming a contractile ring like animal cells do, plant cells divide by the formation of cross walls between the two daughter cells.New cell wall material is brought to the centre in vesicles by the microtubule system forming the phragmoplast a complex organelle consisting of both microtubules and actin filaments.

    Describe the structure of chromosomes of eukaryotes.

    Double-stranded chromosomes have two chromatids; normally, each one is identical to the other. The point where the two chromatids are attached is called the centromere.

    What happens during each of the phases of interphase:. What is the order of these phases? (G1, S, G2).
    G1

    Each chromosome has one chromatid.

    The cell grows in size.

    Synthesis of organelles occurs.

    S

    This is when DNA synthesis occurs.

    G2

    Each chromosome has two chromatids.

    The synthesis of enzymes and other proteins in preparation for mitosis occurs during this period.

    Define Diploid and Haploid.

    Diploid cells (2N) have two complete sets of chromosomes. The body cells of animals are diploid.

    Haploid cells have one complete set of chromosomes. In animals, gametes (sperm and eggs) are haploid.

    Define homologuschromosomes

    Diploid organisms have two copies of each chromosome (except the sex chromosomes). Each pair of chromosomes is homologous. For example, the two #7 chromosomes are homologous. The homologue to the #3 chromosome would be the other #3 chromosome.

    Define centromeres and chromatids.

    A chromatid is a single DNA molecule.

    Double-stranded chromosomes have two chromatids; normally, each one is identical to the other. The point where the two chromatids are attached is called the centromere.

    Define Bivalents and Tetrads.
    They mean the same thing!
    Tetrads are Bivalents and Bivalents are Tetrads!

    Synapsis (joining) of homologous chromosomes produces tetrads (also called bivalents).

    Define gametogenesis, oogenesis, and sprematogenesis.
    Gametogenesis is the formation of gametes. The formation of eggs is oogenesis and the formation of sperm is spermatogenesis.
