* What happens to cells placed in salt water? * SHRINK
Cell Transport Study Guide. 1. Which forms of transport do NOT require energy? Diffusion Osmosis Facilitated Diffusion *All of these are passive!
Cellular Transport Fact: Particles of matter are always in motion no matter what state this random motion helps explain how materials enter and exit the.
Cell Membrane & Cellular Transport Homeostasis – the maintenance of internal stable conditions The cell membrane keeps the cell in balance.
