Question

select the part whose main job is to give shape and organization to the cell. ribosome cytoskeleton cell membrane mitochondria

Explanation:

• Ribosome: Involved in protein synthesis, not cell shape/organization.
• Cytoskeleton: Composed of protein filaments (microtubules, microfilaments, intermediate filaments). Provides structural support, maintains cell shape, and helps in intracellular organization (e.g., organelle positioning).
• Cell membrane: Regulates substance entry/exit, provides some protection, but its main role is not shaping/organizing the cell's internal structure.
• Mitochondria: Powerhouse of the cell (produces ATP), no role in cell shape/organization.

Answer:

cytoskeleton
