Question

eukaryotic cells continually ingest bits of their plasma membrane, along with small amounts of extracellular fluid. the lost pieces of membrane are replaced by what process? choose one: endocytosis exocytosis phagocytosis pinocytosis

Explanation:

Exocytosis is the process by which cells transport vesicles out of the cell, fusing them with the plasma membrane. This replenishes the plasma - membrane pieces lost during endocytosis (including pinocytosis and phagocytosis which are types of endocytosis). Endocytosis involves taking substances into the cell, while exocytosis is the reverse process for membrane replacement.

Answer:

B. exocytosis
