Molecules that cannot pass through a semi-permeable membrane:

Back

All of the above.

Front

Concentration of molecules is higher outside the cell.

Back

hypertonic

Front

Molecule concentration is higher inside the cell.

Back

hypotonic

Front

Concentration of molecules is equal inside and outside the cell.

Back

isotonic

Front

Movement of molecules/ions across a cell membrane without energy

Back

Passive transport

Front

Small hydrophobic materials move straight through the membrane.

Back

Simple diffusion.
