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 encloses extracellular fluid and its dissolved solutes.
3. The pocket pinches off, forming a vesicle within the cell containing the ingested material.
4. The vesicle can then move to different parts of the cell, and the cell can use the solutes for various functions.
