Pinocytosis
Mariana Ruiz Villarreal, WikiCommons
  • 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
