BIO 101 Chapter Notes - Chapter 4: Spectral Shape Analysis, Smallest Organisms, Archaea
Document Summary
4. 1 - what is the cell theory: every living thing is composed of 1 or more cells, smallest organisms are single cells, cells are the functional units of multicellular organisms, all cells arise from preexisting cells. Channel allow passage of specific molecules or ions into or out of cell. Strep bacteria use these: sex long, few in number; binds to nearby bacterium of same type and draws them together. 4. 4 - what are the major features of eukaryotic cells: have organelles membrane enclosed. Plastids: extracellular structures surround animal and plant cells, animal cells : extracellular matrix (ecm) includes array of supporting and adhesive proteins embedded in gel composed of polysaccharides linked by proteins, provides structural and biochemical support. Er: protein is packaged into vesicles and travels to golgi, vesicles fuse with golgi, and carbohydrates are added as protein passes through compartments, completed glycoprotein antibodies are packaged into vesicles on opposite side of.
