A) pinocytosis
B) phagocytosis
C) active transport
D) autolysis
Correct Answer: B
Solution :
The process of engulfing of solid material by infolding of plasma membrane is called phagocytosis. The process of engulfing of liquid material by infoldings of plasma membrane is called pinocytosis. There infoldings close and break off to form fluid - filled vacuoles in the cytoplasm. Active transport is the movement of moecules across a cell membrane in the direction against their concentration gradient, i.e. moving from an area of lower concentration to an area of higher concentration. Autolysis more commonly known as self - digestion. Refers to the destruction of a cell through the action of its own enzymes.
