- Pinocytosis
- Droplets of fluid taken into the cell
- Generates small vesicles
- Usually used for extracellular fluid ingestion
- Requires ATP
- Phagocytosis
- Larger particles of matter taken into the cell
- Usually solid particles ingested
- Cell membrane envelops the fluid or food taking it into the cell
- Lysosomes fuse with the fluid/food vesicle initiating digestion
- Diffusion through the cell membrane allows excretion of metabolic products
