Reasons to study cells: part of the core in biology, fundamental unit of life, storehouse for thousands of genes, determine what is normal so we can fix the abnornmal. Cell biologists look at cell structure, organelles and membrane trafficking, cell cycle and division/death, movement, signalling, communication. Main goal: how macromolecules work together, cells are found in tissues ex. liver has different types of cells, we need to understand how these cell works autonomously (on their own) Once you have the tools, we can start to ask, and more importantly begin to answer, biological questions pertaining to our. You want to isolate an individual cell from complex tissues and grow them under controlled conditions and be able to control cell division, metabolism, etc.
