🏗️ CYTOSKELETON: SKYSCRAPER
PAGE 1 OF 5 — INTERNAL SCAFFOLDING
THE HOOK
A SKYSCRAPER INSIDE EVERY CELL
Cells are not shapeless blobs of jelly. Inside every cell runs a crisscrossing network of protein fibers called the cytoskeleton. Like the steel frame of a skyscraper, these fibers give the cell structure, strength, and shape. They also act as microscopic roads and railway tracks, guiding organelles and molecules to where they need to go. Without a cytoskeleton, cells would collapse, stop moving, and struggle to divide properly.
⚡ DID YOU KNOW?
The cytoskeleton is made entirely of proteins, yet it is strong enough to help whole cells crawl across a surface. White blood cells use their cytoskeleton to chase and engulf invading germs.
