phagocytosis refers to

the nonspecific intake of fluids by the cell.

the fusion of vesicles containing a solid with a lysosome containing digestive enzymes.

the export of solids and small molecules from the cell.

the import of solids and large molecules into the cell using vesicles.

Explanation:

Phagocytosis is a type of endocytosis, a process where cells take in large particles or solids by engulfing them into membrane-bound vesicles. Let's analyze each option:

1. The nonspecific intake of fluids is pinocytosis, not phagocytosis.
2. The fusion of the vesicle with a lysosome is the digestion step after phagocytosis, not the definition of phagocytosis itself.
3. The export of substances from the cell is exocytosis, the opposite of phagocytosis.
4. The import of solids/large molecules via vesicles matches the core definition of phagocytosis.

Answer:

the import of solids and large molecules into the cell using vesicles.
