Introduction to the Cytoskeleton

This set of flashcards covers key vocabulary related to the cytoskeleton, its functions, and the differences between prokaryotic and eukaryotic cells.

Cytoskeleton

A protein-based structure in cells

provides shape,

facilitates movement

holds cellular components together.

No rigid bones

cytoskelton in Prokaryotic Cell

Cytoskeleton positions DNA, segregates the two DNA copies, once complete it cleaves the cell into two during cell division

interacts with cell wall machinery to control cell shape

Main idea

DNA Positioning

segregation during cell division

cell shape

Cytoskeleton role in Eukaryotic Cell

cytoskeleton position organelles in cell

change shape in embryo

make intracellular roadways

-

segregates chromosomes

which then forms daugther cells during cell division

work as intracelluar roadways for motor proteins

form flagella and cilia

form fibroblast

Motor Proteins

Proteins that move along the cytoskeleton, transporting cellular cargo throughout the cell.

Cilia and Flagella

Hairlike structures that extend from the surface of cells, involved in movement and locomotion.

fromed by the cytoskeleton

Fibroblasts

Made by cytoskeleton

Cells that contribute to form connective tissue so once they connect can more through the environment

Intracellular Roadways

Networks within cells along which motor proteins transport cargo.
