| − | *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
