Question

multiple-choice question
the spinosum layer contains some cells that act as ________ and consume worn-out cells or bacteria.
phagocytes
macrophages
bacteriophage

Explanation:

To solve this, we analyze each option:

• Phagocytes: Cells that engulf and digest foreign particles, worn - out cells, or bacteria. The spinosum layer (of the skin, likely) has cells with phagocytic activity.
• Macrophages: A type of phagocyte, but in the context of the spinosum layer, the more general term “phagocytes” or the specific cell type here—wait, actually, the spinosum layer (stratum spinosum) has Langerhans cells which are phagocytic. But among the options, “phagocytes” is the correct functional term here as they consume (phagocytize) worn - out cells/bacteria.
• Bacteriophage: A virus that infects bacteria, not a cell type in the spinosum layer.

So the correct option is phagocytes.

Answer:

A. phagocytes
