<p>The four main stages of mitosis are Prophase, Metaphase, Anaphase, and Telophase. During prophase, the chromosomes condense, and the nuclear envelope breaks down. During metaphase, the chromosomes align at the center of the cell. During anaphase, the sister chromatids separate and move to opposite poles of the cell. During telophase, the nuclear envelope reforms around the separated chromosomes, and the cytoplasm divides, resulting in two daughter cells.</p> Signup and view all the answers

<p>The vacuole, a large, fluid-filled sac within plant cells, plays vital roles in maintaining cell turgor (rigidity), storing nutrients and waste products, and supporting the plant's overall structure. The vacuole's ability to regulate water pressure within the cell contributes to the plant's ability to maintain its shape and stand upright.</p> Signup and view all the answers
