the network of protein fibres and microtubules found within the cell that gives structure and shape to the cell and is responsible for the movement of many materials within it
1 of 15
protein
a polymer consisting of many amino acid monomers covalently bonded together
2 of 15
microtubules
components of the cell cytoskeleton; diameter 24nm but vary in length; involved in moving chromosomes in mitosis, cytokinesis and movement of vesicles within cells
3 of 15
microtubule fibres
proteins associated with microtubules; the proteins can move along the microtubules (kinesin to + end and dynein to - end)
4 of 15
microfilaments
smallest of the protein filaments (7nm diameter) that make up the cytoskeleton, involved in cell division and muscle contraction, cell shape and motility (white blood cells)
5 of 15
undulipodia
longer hair-like extensions that stick out from the surface of eukarytoic cells; each one contains 2+9 microtubules; can be used to move whole cells
6 of 15
prokaryote
an organism with cells that do not contain a true nucleus
7 of 15
flagella
projections from prokaryotic cells made of a spiral of protein called flagellin, and attached by a hook to a protein disc at the base; they are used in movement
8 of 15
cilia
short extensions of eukaryotic cells, typically 2-10 um long and 0.25 um in diameter; used for locomotion or moving fluids or mucus over a surface
9 of 15
actin
the protein that makes up microfilaments
10 of 15
flagellin
a spiral of protein, attached to a hook in the flagella of prokaryotes
11 of 15
dynein
the protein motor found in undulipodia
12 of 15
plasmid
small loop of DNA found in prokaryote cells
13 of 15
cellulose
the carbohydrate polymer that forms a sieve-like network of strands that strengthens cell walls
14 of 15
murein
peptidoglycan that usually makes up the cell walls of prokaryote cells
