Which process describes the way a cell takes in material by forming a vacuole around it?

• A. Diffusion
• B. Endocytosis
• C. Exocytosis
• D. Osmosis

Answer: (B)

Verified step by step guidance

1. Understand the key terms provided in the question: Diffusion, Endocytosis, Exocytosis, and Osmosis. Each term describes a different cellular process.
2. Recall that endocytosis is the process by which a cell engulfs material from its surroundings by forming a vacuole or vesicle around it. This is typically used to transport large molecules or particles into the cell.
3. Differentiate endocytosis from exocytosis, which is the process of expelling material from the cell by merging a vesicle with the cell membrane.
4. Recognize that diffusion refers to the passive movement of molecules from an area of higher concentration to an area of lower concentration, and osmosis specifically refers to the diffusion of water across a semipermeable membrane.
5. Conclude that the process described in the question, where a cell takes in material by forming a vacuole, matches the definition of endocytosis.
