,Concept 6.6: The Cytoskeleton is a Network of Fibres
That Organizes Structures and Activities in the Cell
• The cytoskeleton is a Figure 6.20
network of fibres extending
throughout cytoplasm
• It organizes the cell’s
structures and activities,
anchoring many organelles
,Cytoskeleton Organizes Structures and
Activities in Cells
• The cytoskeleton is composed of three types of structures
– microtubules
– microfilaments
– intermediate filaments
• It provides support to the cell and maintains its shape
• The cytoskeleton also carries out cell motility
– within the cell as a track for organelles to move along
in the cell
– for entire cells, changes cell shapes as cells migrate
