The movement of molecules  or ions from high concentration to low concentration

• osmosis
• diffusion
• hypotonic
• isotonic

The diffusion of water from high concentration to low concentrations of water

• hypertonic
• hypotonic
• osmosis
• isotonic

What molecules move through a semipermeable membrane?

• water and hydrophobic
• water and hydrophyllic
• isotonic
• exocytosis

What molecules cannot move through a semi-permeable membrane

• charged ions
• polar proteins
• sugars
• all of the above

the concentration of molecules is higher outside the cell

• isotonic
• hypertonic
• hypotonic
• passive transport

The concentration of molecules is higher inside the cell

• hypertonic
• isotonic
• hypotonic
• passive trnasport

the concentration of molecules is equal inside and outside of the cell

• passive transport
• isotonic
• hypertonic
• hyypotonic

Any movement of molecules/ions across a cell membrane that does not require energy

• active transport
• Passive transport
• exocytosis
• endosytosis

small hydrophobic materials that move  straight through the membrane

• active transport
• passive transport
• isotonic
• simple diffusion

any movement  of ions or molecules across a cell membrane hat requires energy

• exocytosis
• passive transport
• endocytosis
• active transport
