The process by which a cell ingests extracellular fluid and its dissolved solutes is called pinocytosis.

Here's a step-by-step explanation:

1. The cell surface indents, forming a small pocket.
2. The pocket deepens and seals off, forming a vesicle filled with extracellular fluid and its dissolved solutes.
3. The vesicle detaches from the cell surface and moves into the cell, where the solutes can be released and used by the cell.

This process is a type of endocytosis, but it's specifically called pinocytosis because it involves the ingestion of liquid rather than solid particles.
