chapter 3.4

• endomembrane system: an interconnected set of membranes in eukayrotes that defines spaces in the cell
• nuclear envelope: double-membraned structure surrounding the nucleus, composed of nuclear pores which allow transport between cytoplasm and nucleoplasm
• endoplasmic reticulum: a network of membranes that forms a continuous sheet throughout the cell
• golgi aparatus is a series of membrane bound flattened sacs that are involved in the modification and packaging of proteins
• lyosome: a membrane-bound vesicle that is used to transport substances between the cell and the extracellular environment
• vesicles: small membrane-bound sacs that transport substances between the cell and the plasma membrane
• cell membranes: controls what goes in and out of the cell, controls what goes on the cell
• the nucleus is enclosed by the nuclear envelope which houses the genome
• the endoplasmic reticulum is continuous with the outer nuclear envelope and manufactures proteins and lipids for use by the cell or for export
• the golgi apparatus communicates with the endoplasmic reticulum by transport vesicles, it recieves proteins and lipids from endoplasmic reticulum and directs them to their final destinations
