Compare and contrast the passive and active cellular uptake of glucose molecules and ions

Passive transport does not require energy for the transport of molecules where active transport requires energy for transport.

Active transport VS passive transport A glucose is a large molecule so its diffusion across a membrane is difficult that's why it diffuses across membranes through facilitated diffusion against the concentration gradient.While on the other hand, Active transport is the movement of molecules into or out of a cell through the cell membrane, from a region of lower concentration to a region of higher concentrationso we can conclude that passive transport does not require energy for the transport of molecules where active transport requires energy for transport.
