Final answer:

The three basic cytoskeletal elements in eukaryotes are microtubules, microfilaments, and intermediate filaments. These elements are composed of tubulin dimers, actin, and various proteins to contribute to cell structure, movement, and organelle anchoring.

Step-by-step explanation:

The three basic cytoskeletal elements in eukaryotes are microtubules, microfilaments, and intermediate filaments. Microtubules are composed of tubulin dimers and form hollow tubes, providing structural support and serving as tracks for motor proteins. Microfilaments are made of actin and contribute to cell shape and movement. Intermediate filaments provide tension and anchor organelles in place.
