Document Summary
Ahs 150 lecture 4 study notes unit 1 levels of organization. Chapter 3 the cellular level of organization. Overview: the functions of tissues and organs depend on cells that are highly specialized in both their structure and function, basic structure and function of all animal cells, how cell become specialized. The cell theory: all organisms are composed of one or more cells, the cell is the smallest unit that has the properties of life, cells arise only from the growth and division of preexisting cells. Parts of the cell: plasma membrane, cytoplasm, cytosol: semi-fluid, gel-like substance where many enzymatic reactions occur, organelles, cytoskeleton, ribosomes, endoplasmic reticulum, golgi complex, lysosomes, Mitochondria, peroxisomes: nucleus, largest organelle, the information center of the cell. Structure and composition of the cell membrane: bilayer of phospholipids. Integral membrane proteins: embedded in the membrane so spans the lipid bilayer.
