Molecules that are too large to pass through the pores of a cell membrane may enter the cell by a process known as:
A. cyclosis.
B. synthesis.
C. hydrolysis.
D. pinocytosis.
Pinocytosis, or pinching in of the cell membrane, allows cells, such as the Paramecium, to capture larger food molecules. Hydrolysis is the process of using water to split molecules apart. Cyclosis is a mechanism for transporting materials within a cell, by the cytoplasm swirling. Synthesis is the process of building up molecules within the cell.
