What specific changes in the cell cycle occur during mitosis in a plant cell?
During mitosis in a plant cell, the cell undergoes several specific changes in the cell cycle. These changes include prophase, where the chromosomes condense and the nuclear envelope breaks down; metaphase, where the chromosomes line up at the center of the cell; anaphase, where the sister chromatids separate and move towards opposite poles of the cell; and telophase, where the nuclear envelope reforms and the chromosomes decondense. This process ensures that each daughter cell receives an identical set of chromosomes.
What replicates during mitosis in a cell?
During mitosis, the cell's DNA replicates.
What becomes visible under a microscope during prophase?
During prophase, chromatin condenses into visible chromosomes, the nuclear envelope breaks down, and the spindle fibers begin to form. These changes prepare the cell for metaphase, where the chromosomes will align in the center of the cell.
Do chromosomes undergo crossover during mitosis?
No, chromosomes do not undergo crossover during mitosis. Crossover, also known as genetic recombination, occurs during meiosis, not mitosis.
Why does nucleolus disappear during pro-phase of mitosis and what is the mechanism of dissapearence?
The nucleolus disappears during prophase of mitosis because it is the stage where the nuclear envelope breaks down, causing the nucleolus to disperse. This disappearance is due to the disassembly of the nucleolar components and the redistribution of its content throughout the cell.

What tool is good to observe mitosis?
A good tool to observe mitosis is a light microscope, which allows researchers to view cells at high magnification. Staining techniques, such as using methylene blue or Giemsa stain, can enhance visibility of chromosomes and cell structures during different stages of mitosis. Additionally, time-lapse microscopy can be used to capture dynamic processes in living cells as they undergo mitosis.

What process can Genetic changes in mitosis can only occur by?
Genetic changes in mitosis can only occur through mutations, which are changes in the DNA sequence. These mutations can be caused by errors during DNA replication, exposure to mutagens like radiation or chemicals, or spontaneous changes in the DNA.
Does the nucleus disappear during mitosis and meiosis?
No, the nucleus does not disappear during mitosis or meiosis. It undergoes changes in structure and organization, such as condensation of the chromatin into visible chromosomes, but the nucleus remains present throughout these processes to ensure proper segregation of genetic material.
What guide chromosomes during mitosis?

What replicates during mitosis in a cell?

Mitosis
What becomes visible under a microscope during prophase?
During prophase, chromatin condenses into visible chromosomes, the nuclear envelope breaks down, and the spindle fibers begin to form. These changes prepare the cell for metaphase, where the chromosomes will align in the center of the cell.
What type of chromosome is produced during mitosis?
All chromosomes are reproduced during mitosis.
