*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[[Category:Protozoa]]
