Question

certain white blood cells such as neutrophils and monocytes are capable of a process shown below. what is this process called? three pictures of white blood cells showing pic 1: white blood cell (phagocyte) and bacteria outside the white blood cell, pic 2: showing pseudopodia engulfing bacteria and pic 3: showing bacteria are digested. options: pinocytosis, phagocytosis, receptor mediated endocytosis, pseudoposis

Explanation:

1. Analyze each option:

• Pinocytosis: Involves the uptake of fluid and small solutes, not large particles like bacteria.
• Phagocytosis: Is the process by which cells (like phagocytes, including neutrophils and monocytes) engulf large particles or microorganisms (like bacteria) via pseudopodia, followed by digestion. This matches the described process.
• Receptor - mediated endocytosis: Requires specific receptors and is for specific molecules, not for engulfing whole bacteria.
• Pseudoposis: Not a recognized cellular process for engulfing particles.

Answer:

B. phagocytosis
