Why do plants lack phagocytosis cells?
Plants lack phagocytosis cells because they do not need to engulf and digest other cells as animals do. Instead, plants have developed rigid cell walls and specialized defense mechanisms, such as chemical signaling and physical barriers, to protect themselves from pathogens. Their nutrient acquisition primarily relies on absorption through roots and photosynthesis, rather than predation or scavenging. Consequently, phagocytosis is not a necessary function for their survival.
