Question 1

semi-permeable

Answer 1

a barrier that allows some substances but not all, to pass through it

Question 2

solute

Answer 2

a substance that dissolves in a solution

Question 3

solvent

Answer 3

the substance that does the dissolving

Question 4

diffusion

Answer 4

The passive movement of molecules from an area of high concentration to low concentration

Question 5

osmosis

Answer 5

the movement of water or other solvent molecules across a semi-permeable membrane from one area of high water concentration (low solute concentration) to an area of low water concentration (high solute concentration)

Question 6

hypertonic

Answer 6

having a high concentration of solutes than a comparison fluid, causing water to move toward it.

Question 7

hypotonic

Answer 7

A hypotonic solution has a lower solute concentration than another solution, which causes water to move into the cell via osmosis, making it swell.

Question 8

isotonic

Answer 8

Having the same concentration of a substance, such as solutes in a solution or tension in a muscle.

Question 9

transport proteins

Answer 9

Transport proteins are integral membrane proteins that facilitate the movement of molecules across cell membranes

Question 10

endocytosis

Answer 10

an active process where cells engulf substances from the outside, forming a vesicle that moves into the cells interior.

Question 11

phagocytosis

Answer 11

The process by which a cell engulfs and destroys large particles, such as microorganisms or dead cells.

Question 12

pinocytosis

Answer 12

The process by which a cell takes in fluids and dissolved substances from its external environment through invagination of the cell membrane.

Question 13

receptor mediated

Answer 13

A process where cells absorb specific molecules from their environment by using special receptor proteins on their surface.
