Question

mitosis card sort directions: place diagrams in correct order. describe what is happening with the chromosomes and other structures in the blue text box. prophase metaphase anaphase telophase

Explanation:

1. Prophase: Chromosomes condense from chromatin, the nuclear envelope breaks down, and spindle fibers start to form from centrosomes that move to opposite poles of the cell.
2. Metaphase: Spindle fibers fully form, and condensed chromosomes line up single-file along the metaphase plate (the equator of the cell), with each chromosome's centromere attached to spindle fibers from opposite poles.
3. Anaphase: Sister chromatids are pulled apart at their centromeres by shortening spindle fibers, and the separated chromatids (now individual chromosomes) are dragged to opposite ends of the cell.
4. Telophase: Chromosomes reach the opposite poles, decondense back into chromatin, the nuclear envelope reforms around each set of chromosomes, spindle fibers disassemble, and the cell begins to undergo cytokinesis (pinching into two).

Answer:

1. Prophase: Chromosomes condense; nuclear envelope breaks down; spindle fibers form.
2. Metaphase: Chromosomes align at the cell's equator.
3. Anaphase: Sister chromatids separate and move to poles.
4. Telophase: Chromosomes decondense; nuclear envelopes reform; cell prepares to split.

Order of stages: Prophase → Metaphase → Anaphase → Telophase
