Document Summary

Module 3 online notes (sec 3. 1 to 2. 7) Our organs and systems rely upon the complex functioning of these cells. Cell membrane primary function of plasma membrane is to regulate passage of substances into and out of the cell. It allows certain molecules to cross the membrane while excluding other molecules. It also plays in important role in detecting chemical signals from other cells and in forming physical links with adjacent cells. Endoplasmic reticulum continuation of the cell"s nuclear membrane, it is the site for the synthesis, storage and transport of proteins and molecules. Rough er covered with rows of ribosomes, it is the site of protein synthesis. These proteins are packaged into vesicles that transport them to the golgi. Smooth er lacks ribosomes, responsible for the synthesis of lipids and fatty acids. Nucleolus dense body within nucleus contains specific dna that produces rna found in ribosomes. Mitochondrion membrane organelle where most of the atp is generated.
