Question

1. take a picture of your model and submit it in gc in the link titled cell cycle picture submission. make sure to include all lab partners names.
2. explain what happens in each phase of the cell cycle in the chart below:

phase	justification (what represents what in your model)	what is happening?
metaphase
anaphase
telophase
cytokinesis

Explanation:

The table is completed with standard cell cycle (mitosis + cytokinesis) events, and a common model representation (using paper cutouts/physical objects) is provided for justification:

1. Prophase: Chromosomes condense, nuclear envelope breaks down, spindle forms. A typical model uses colored paper strips (condensed chromosomes), a removed paper circle (broken nuclear envelope), and string (spindle fibers).
2. Metaphase: Chromosomes align at the cell's equatorial plate. A model would place the chromosome cutouts in a straight line across the center of a paper cell outline.
3. Anaphase: Sister chromatids separate and move to opposite cell poles. A model would pull the paired chromosome cutouts apart toward opposite ends of the cell outline.
4. Telophase: Chromosomes decondense, nuclear envelopes reform, spindle breaks down. A model would add new paper circles (new nuclear envelopes) around chromosomes at each pole, and the chromosome cutouts can be "unfolded" to represent decondensation.
5. Cytokinesis: The cell cytoplasm splits into two daughter cells. A model would draw a line (or use a physical divider) down the center of the cell outline to split it into two separate cells.

Answer:

Phase	Justification (what represents what in your model)	What is happening?
Metaphase	Chromosome cutouts aligned at the center of a paper cell outline	Chromosomes line up at the cell's equatorial plate
Anaphase	Separated chromosome cutouts pulled toward opposite ends of the cell outline	Sister chromatids split and move to opposite cell poles
Telophase	New paper circles (nuclei) around chromosomes at each pole; "unfolded" chromosome cutouts	Chromosomes decondense; new nuclear envelopes form; spindle breaks down
Cytokinesis	Divider line splitting the paper cell outline into two	Cytoplasm divides, forming two genetically identical daughter cells
