Summary

BIOSCI 107: Cell structure and function mind-map,
quick overview of the cell's major organelles....

Description

Diameter 7nm Comprised of actin molecules assembles in 2 long chains, twisted around each other

STUCTURE

Found around the periphery and lining of the interior of cell

CYTOSKELENTON: MICRO FILAMENTS

Bear tension and weight by anchoring cytoskeleton to plasma membrane proteins Promotes amoeboid motil ity if required e.g macrophage

FUNCTION

Assembled and disassembled as requiredDYNAMIC

8-12 nm in diameter Comprised of diverse range of different materials e.g KERATIN

STUCTURE

Found in cytoplasm of the cell

CYTOSKELENTON: INTERMEDIATE FILAMENTS

Bear tension and weight throughout cell e.g during cell anchoring Acts as scaffold for cellular organelles e.g nucleus

FUNCTION

The most paermants part of the cytoskeleton

Tubular structure, 25 nm, central lumen 15 nm STRUCTURE Comprised of tubulin dimers (alpha & beta), coiled to form a tube

CYTOSKELENTON: MICRO TUBLES

Support cell shape and size Guide for movement of organelles e.g vesicles from golgi to membrane Chromosome organization - cell division

FUNCTION

Support & movement of cilia/flagella Assembled and disassembled as required are DYNAMIC

Cylindrical shaped Inner: folds of cristae, intermembrane space Outer: mitochondrial membrane Fluid filled interior cavity called

STUCTURE...
