Answer

Chemotaxis Formation of phagosome Killing and digestion of microbe Formation of phagolysosome Exocytosis of debris

  • Q:What is phagocytosis? A:Phagocytosis is the process by which cells engulf and digest microorganisms and cellular debris.
  • Q:What are the stages of phagocytosis? A:The stages of phagocytosis are chemotaxis, formation of phagosome, killing and digestion of microbe, formation of phagolysosome, and exocytosis of debris.
  • Q:What is chemotaxis? A:Chemotaxis is the process by which cells move towards a chemical signal, such as a chemical released by a microorganism.
  • Q:What is the first stage of phagocytosis? A:The first stage of phagocytosis is chemotaxis, the process by which cells move towards a chemical signal, such as a chemical released by a microorganism.
  • Q:What is the second stage of phagocytosis? A:The second stage of phagocytosis is the formation of phagosome, the process by which the cell membrane engulfs the microorganism to form a phagosome.
  • Q:What is the third stage of phagocytosis? A:The third stage of phagocytosis is killing and digestion of the microbe inside the phagosome.
  • Q:What is the fourth stage of phagocytosis? A:The fourth stage of phagocytosis is the formation of the phagolysosome, the process by which the phagosome fuses with a lysosome to form a phagolysosome.
  • Q:What is the final stage of phagocytosis? A:The final stage of phagocytosis is exocytosis of debris, the process by which the cell releases digested debris from the phagolysosome.
