Cell Parts and FunctionsEndoplasmic Reticulum (E.R.)Transports materials and sends messages to all parts of the

cellTwo types: smooth and rough (has ribosomes)Location: attaches from cell membrane to nuclear

membrane

CYTOSKELETONFunction: Support structure of cell and

transport materials/organelles throughout the cell.

The highway of the cell.

Made of Microtubules (thin hollow cylinders) and Microfilaments (thin solid cylinders)

Location: Inside the cell
