Question

task 3: look at the diagram below. write what do you notice about each level of mitosis in the boxes to the right? interphase the nucleolus and the nuclear envelope are distinct and the chromosomes are in the form of threadlike chromatin. prophase the chromosomes appear condensed, and the nuclear envelope is not apparent. metaphase thick, coiled chromosomes, each with two chromatids, are lined up on the metaphase plate. anaphase the chromatids of each chromosome have separated and are moving toward the poles. telophase the chromosomes are at the poles and are becoming more diffuse. the nuclear envelope is reforming. the cytoplasm may be dividing. cytokinesis division into two daughter cells is completed.

Explanation:

• Interphase: Notice that the cell appears normal with a well - defined nucleus and nucleolus, and the chromosomes are in the form of thin, threadlike chromatin.
• Prophase: The chromosomes have condensed and become visible, and the nuclear envelope is starting to break down.
• Metaphase: The chromosomes, each with two chromatids, are precisely lined up on the metaphase plate, showing a high level of organization.
• Anaphase: The sister chromatids of each chromosome have separated and are moving towards the opposite poles, indicating the distribution of genetic material.
• Telophase: Chromosomes are at the poles and are de - condensing back into chromatin. The nuclear envelope is reforming and cytokinesis may be starting to divide the cytoplasm.
• Cytokinesis: The cell has divided into two daughter cells, completing the cell division process.

Answer:

• Interphase: The cell has a distinct nucleus and nucleolus with chromatin in a threadlike form.
• Prophase: Chromosomes are condensed and the nuclear envelope is disappearing.
• Metaphase: Chromosomes with two chromatids are lined up on the metaphase plate.
• Anaphase: Sister chromatids are separating and moving to the poles.
• Telophase: Chromosomes are de - condensing and the nuclear envelope is reforming.
• Cytokinesis: The cell has divided into two daughter cells.
