Which intracellular structure primarily helps animal cells maintain their shape?

• A. Golgi apparatus
• B. Lysosome
• C. Cytoskeleton
• D. Mitochondrion

Answer: (C)

Verified step by step guidance

1. Understand the function of each listed intracellular structure: The Golgi apparatus is involved in modifying, sorting, and packaging proteins and lipids for secretion or use within the cell. Lysosomes are responsible for breaking down waste materials and cellular debris. Mitochondria are the powerhouses of the cell, generating ATP through cellular respiration. The cytoskeleton provides structural support and helps maintain the cell's shape.
2. Recognize that maintaining cell shape is primarily a structural function, which aligns with the role of the cytoskeleton.
3. Learn about the components of the cytoskeleton: It consists of microfilaments (actin filaments), intermediate filaments, and microtubules, each contributing to cell shape, stability, and intracellular transport.
4. Understand how the cytoskeleton interacts with other cellular components: It anchors organelles, facilitates intracellular transport, and enables cell movement through dynamic rearrangements.
5. Conclude that the cytoskeleton is the correct answer because it is the intracellular structure responsible for maintaining the shape of animal cells.
