Endocystosis/phagocytosis

Question 1

Active process of cell membrane engulfing material, bringing it into cell in a vesicle

Question 2

Answer 2

Active process of cell membrane engulfing large particles, brining into cell by vesicle

Question 3

Answer 3

1) bacterium fits into receptor on phagocyte membrane. (Phagocyte is type of WBC that engulfs)
