Final answer:
The cell's structure is maintained by the cytoskeleton, which is a network of protein filaments, including microtubules. If these are not functioning correctly, the cell would lose its shape, which seems to be the case in the scenario described.
Step-by-step explanation:
If a cell is crumbling and closing in on itself as if it's missing its 'bones', it's likely an issue with the organelles that contribute to the cell's structure and shape. In eukaryotic animal cells, this supportive framework is provided by the cytoskeleton. The cytoskeleton is a network of protein filaments that includes microfilaments, intermediate filaments, and microtubules, with each component serving unique functions in maintaining cell shape, providing internal organization, and enabling cell movement and division. Therefore, if these organelles are not performing their job, the cell could lose its integrity and structure just like a bag of Jell-O without a container.
