Biol 253 Exam 1 All Answers Correct universal function of membranes to act as a selective barrier to the passage of molecules functions of plasma membranes 1. regulate passage of substances in and out of cells and between cell organelles and cytosol 2. detect chemical messengers arriving at the cell surface 3. link adjacent cells together by membrane junctions 4. anchor cells to the extracellular matrix integral membrane protein closely associated with membrane lipids can't be e...

IB Biology Topic 1: Cell Biology Latest Update Graded A Cell theory The theory that cells form the fundamental structural and functional units of all living organisms. Differentiation The expression of a particular gene(s) and not others in order for cell specialisation. Emergent properties The idea that the sum of an organism is more than the parts interacting and combining. Living things become more complex as they move (from individual cells to organ systems). Multicellular...
