Step by step
Solved in 3 steps
- Which of the following is not true about phagocytosis?(a) It is a form of exocytosis.(b) It is energy dependent.(c) It only occurs in eukaryotes.(d) A larger cell engulfs a smaller cell that will eventually bepresent in an internal vacuole.(e) It requires fusion of internal lysosomes to engulfed vac-uole for contents to be digestedWhat is phagocytosis? What function does it serve?What would happen if a bacterium could prevent the phagosome from fusing with lysosomes?
