Active transport
__________ Is the infolding of a cells membrane around liquid droplet to bring it into the cell
Pinocytosis
In passive transport p net movement if substances is (up, down) their concentration gradient.
Down
Movement of any substances from a high concentration to a low concentration whether or not a membrane is involved is called
Simple diffusion
Movement of a substance from a low concentration to high concentration is
Active transport
