Chapter 3: Cell Structure and FunctionCharacteristics of Living Organisms All living organisms are made up of cells They share the following four processes: Growth:Increase in size Reproduction: Increase in number Responsiveness: React to environment Metabolism: Chemical reactions to provide energy and structures needed to grow, reproduce, and respond to environmentDistinguishing Features of ProkaryoticCells:1. DNA is: Notenclosed within a nuclearmembrane. A singlecircularchromosome. Notassociated with Lackmembrane-enclosed organelles like mitochondria, chloroplasts, Golgi, Cell walls usually contain peptidoglycan, a complex Divide by Features of EukaryoticCells:1. DNA is: Enclosed within a nuclearmembrane. Several linear chromosomes.
