Mitotic Cell Cycle Stages — a labelled NEET Biology diagram with a definitions lexicon.
Mitotic Cell Cycle Stages Labelled parts: Prophase, Condensing chromosomes, Nuclear envelope breaking down, Centrosomes, Spindle fibers, Metaphase, Kinetochores, Metaphase plate, Anaphase, Sister chromatids, Separating to poles, Shortening spindle fibers, Telophase and cytokinesis, Nuclear envelope reforming, Chromosomes at equatorial plate, Two daughter cells, Plant cell cytokinesis (inset), Cell plate. A type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus. FYI: Mitosis is crucial for growth, repair, and asexual reproduction, ensuring genetic continuity. Organelles found in animal cells that organize the microtubule-based spindle fibers during cell division. FYI: Centrosomes replicate during the S phase and move to opposite poles of the cell before mitosis begins. Microtubule structures that form the mitotic spindle and are responsible for separating and moving chromosomes to opposite poles during cell division. FYI: Spindle fibers are composed of tubulin protein subunits and are essential for accurate chromosome segregation. Protein complexes assembled on the centromere region of a chromosome, serving as the attachment point for spindle fibers. FYI: Kinetochore microtubules attach specifically to the kinetochore region, ensuring proper tension and movement of sister chromatids. Two identical copies of a chromosome, joined together at the centromere, that are present after DNA replication. They separate during anaphase of mitosis and meiosis II. FYI: Before replication, a chromosome consists of one chromatid; after replication, it consists of two sister chromatids. A membrane-bound structure formed during cytokinesis in plant cells, which grows outward from the center to divide the parent cell into two daughter cells. FYI: The cell plate is formed by the fusion of Golgi-derived vesicles containing cell wall materials (pectin and cellulose).
