Biology: Cell Membrane and Cell Transport

Active transport is different from passive transport in that active transport involves:

• the movement of molecules from high concentration to low concentration

• an expenditure of energy

• the use of ribosomes

• a process which occurs only in the cells of simple plants and animals

The method of transport that allows molecules to move into and out of the cell without energy from areas of high concentration to areas of low concentration is called...

• passive transport

• osmosis

• active transport

• pump

The movement of WATER across the cell membrane or any semi-permeable membrane through the use of aquaporins is described as _______.

• osmosis

• active transport

• diffusion

• neuron relay

When two solutions have the same solute concentration we would say that they are...

• isotonic

• hypertonic

• hypotonic

• solute

When comparing two solutions side by side, we call the solution that contains a lower solute concentration _______.

• hypotonic

• hypertonic

• isotonic

• solute

The ___ is the fundamental unit of life that specializes and joins others like it to form tissues in an organism, providing it with structure and giving it function

• atom

• cell

• matter

• all other answers are correct
