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...

Job Production - where a single product is made at a time Advantages of Job Production - high quality due to skilled workers, motivated due to variable work, customised products, premium price Disadvantages of Job Production - high labour costs, slow production, expensive specialist tools, generally expensive method of production Batch Production - a method that involves completing one operation at a time on all units before performing the next Advantages of Batch Product...

Production - The transformation of resources into goods or services Job production - where a single product is made at a time Batch production - where one type of product is made and then settings / inputs are changed to manufacture another type. This is repeated to produce those products which are needed when demand dictates Flow production - producing items in a continually moving process / assembly line Cell production - Splitting flow production into self-contained...
