What is fagocytosis?

Answer 1

I think you meant phagocytosis which is when a cell wraps itself around the food particle and engulfs it. Enzymes are then poured into the food vacuole to digest the food into small soluble particles which are then absorbed. In other words, it's a mode of nutrition.

Answer 2

Phagocytosis is a process in which cells engulf and digest foreign particles, such as bacteria or dead cells, to protect the body from harmful invaders. This process is primarily carried out by specialized immune cells called phagocytes, including neutrophils, macrophages, and dendritic cells.
