Osmosis, Endocytosis, and Exocytosis

Osmosis

the movement of water across the cell membrane

• facilitated diffusion

• Aquaporin (protein channel is used)

Endocytosis

• takes in marcomolecules & particulate mater by forming new vesicles

• uses energy

• (Inside Cell Process)

Phagocytosis

• takes in large particles via vacuoles

• (Eating Cell Process)

Pinocytosis

• the cell taking in extracellular fluid containing dissolved particles

• Drinking cell process

Receptor- Mediated Endocytosis

• receptor proteins on the cell membrane being used to capture specific molecules

Vesicles

Vesicles hlep facilitate movement of things in and out the cell
