Cell Transport Lesson

What is the term for the diffusion of water across a semipermeable membrane?

• isotonic

• osmosis

• concentration gradient

• facilitated diffusion

The movement of molecules down a concentration gradient through transport proteins in the cell membrane is a type of

• Selective transport

• endocytosis

• osmosis

• facilitated diffusion

This releases substances outside a cell

• endocytosis

• Both

• exocytosis

In which solution will water move out of the cell resulting in the cell shriveling up?

• Hypertonic

• Hypotonic

• Isotonic

Passive transport requires no

• motion

• concentration gradients

• energy

• osmosis

What is the state of relatively constant internal physical and chemical conditions

• Homeostasis

• Diffusion

• Mitosis

• Facilitated Diffusion
