Biology crossing plasma membrane

passive transport

requires NO energy

Active transport

REQUIRES energy (moving against concentration)

(simple) Diffusion

movement of molecules from HIGHER concentration to LOWER. (passive transport)

osmosis

movement of water molecules across plasma membrane. (passive)

Isotonic

soultion will not meet movement of water (evenly distributed)

Hypotonic

Less solute, this causes lysis. (passive)

lysis

cell in a hypotonic solution will burst. (passive) (general term)

Hypertonic

more solute, this causes crenation

solute

the substance BEING dissolved

solvent

DOING the dissolving

Solution

finale mixture/product

crenation (passive)

It shrivels

facilitated diffusion

movement of molecules using a carrier molecule (passive)

EXOcytosis

movement of molecules out of the cell (exit) (active transport)

ENDOcytosis

Movement of molecules into the cell membrane and pinching off to make vesicle. (into) (active transport)

cytolysis

SPECIFIC bursting of cell membrane (passive)

Plasmolysis

lack of water (cell membrane shrinks due to water pressure)

Turgor pressure

Water pressure inside of plant cell
