Cell Move Form Outline Structure Function Component Cytoskeleton

Cytoskeleton components include microfilaments (contractile actin for movement and cytokinesis), microtubules (tubulin for scaffold and organelle tracks), and intermediate filaments (for added strength).

Los componentes del citoesqueleto incluyen microfilamentos (actina contráctil para movimiento y citocinesis), microtúbulos (tubulina para soporte y transporte de orgánulos) y filamentos intermedios (para mayor resistencia).

Components
  • Microfilaments - contractile fibers of actin, allow cells to move + cytokinesis (fibers can get shorter/longer which allows the cell to move)
  • Microtubules - tubes made of chains of globular tubulin, form scaffold to maintain cell shape and form track ways along which organelles can move around within the cell
  • Intermediate filaments - provide additional strength to support the cell
