Cellular Transport PRACTICE

Allows certain substances to pass through..."picky"!

• selectively permeable

• proteins

• osmosis

Transport of molecules across a membrane WITHOUT using energy.

• Active Transport

• Passive Transport

• Diffusion Transport

Surrounds and protects the cell... aka the cell membrane.

• Cell wall

• Hyper membrane

• Plasma Membrane

The diffusion of water is called...

• active transport

• osmosis

• Regular transport

Everything on both sides of the membrane is EQUAL.

• dynamic equilibrium

• hypotonic

• hypertonic

Also in the plasma membrane, they transport big materials and are used for cell communication

• proteins

• nucleic acids

• fatty acids

The spreading out of molecules from high to low concentrations is called

• plain transport

• active transport

• diffusion

High concentration of solutes outside the cell...salt or sugar water!!!

• hypertonic solution

• hypotonic solution

• isotonic solution

Same concentration of solutes inside and outside the cell is called...

• hypertonic solution

• hypotonic solution

• isotonic solution

Low concentration of solutes outside of the cell...distilled water!

• hypertonic solution

• hypotonic solution

• isotonic solution
