Cell Cycle & Differentiation Study Guide (Axolotl)

Based on your graph, what patterns or trends do you see?

• the line is increasing

• the line is decreasing

• the line is goes up and down

• the line remains the same

Based on your graph, what does the pattern or trend mean?

• the number of new limb cells formed increases with time

• the number of new limb cells formed decreases with time

• the number of new limb cells formed stays the same as time passes

• the number of new limb cells formed increases and decreases with time

After analyzing the data, which hypothesis would you suggest the regenerative scientists use for their experiment?

• If an axolotl limb is lost, then regeneration occurs at a constant rate regardless of time after injury.

• If an axolotl limb is lost, then the number of new limb cells increases over time but slows down as regeneration nears completion.

• If an axolotl limb is lost, then axolotl limb cells regenerate at the same rate as human skin cells.

• If an axolotl limb is lost, then regeneration only occurs within the first 30 hours after injury, then stops completely.

How many new limb cells would likely be present after 80 hours?

• 1000 cells

• 2000 cells

• 3000 cells

• 4000 cells

Which cellular process is responsible for producing the new cells observed in your graph?

• Mitosis

• Photosynthesis

• Respiration

• Meiosis

Based on the experiment, what is the dependent variable?

• Time After Injury

• Limb Cell Regeneration Time

• Number of New Limb Cells

• Number of Differentiated Cells

Based on the experiment, what is the independent variable?

• Time After Injury

• Limb Cell Reverberation Time

• Number of New Limb Cells

• Number of Differentiated Cells

The primary purpose of mitosis in axolotl cells after a limb loss is:

• To repair and replace damaged cells

• To create genetically diverse cells

• To produce energy for cell functions

• To improve the axolotl's immune response

A researcher observed uncontrolled cell growth in an axolotl during limb regeneration. Which cellular process is likely not functioning properly?

• Mitosis

• Osmosis

• Meiosis

• Differentiation

Stem cells play a crucial role in limb cell regeneration by:

• differentiating into various cell types needed for repair

• acting as a barrier to prevent infection

• providing energy to damaged cells

• removing waste products from the site of injury
