- Bulk Transport - Large particles (or large groups of smaller particles) moving in/out of the cell.
General term for several types of active transportations into the cell by enclosing them in a vesicle made out of plasma membrane.
LIT: Cell eating.
A form of endocytosis... large particles are transported into cell.
EX: "macrophage to engulf a pathogen"/"amoebas"/"white blood cells".
"Single-celled eukaryotes called amoebas also use phagocytosis to hunt and consume their prey" --https://www.khanacademy.org/science/biology/membranes-and-transport/bulk-transport/a/bulk-transport
- Cell engulfs target particle
- Pocket with particle pinches off the membrane, forming a food vacuole.
- Food vacuole fuses with lysosome.
- Lysosome uses enzymes to break down target particle.
- Lysosome uses target particle's basic components, like amino acids and sugars, for the cell.
LIT: Cell drinking.
Form of endocytosis, cell takes in extracellular fluids.
external transport mechanism - opposite of "endocytosis".
Materials are transported from the inside of the cell to the outside of the cell.
- Using vesicles and the plasma membrane.
