Question

question 53
amoebocytes in a sea star immune function as plasmatocytes in a fruit fly. what function do these cell types have?
a they are both phagocytic cells.
b they are both mucous membranes.
c there are no common characteristics between these.
d they both are enzymes that inhibit bacterial growth.
e they are both innate physical barriers.

Explanation:

To solve this, we analyze each option:

• Option A: Amoebocytes in sea stars and plasmatocytes in fruit flies are both phagocytic cells (part of the immune system, engulfing pathogens).
• Option B: Mucous membranes are tissues, not cells like amoebocytes/plasmatocytes. Eliminate B.
• Option C: They do share a phagocytic function, so C is wrong.
• Option D: These are cells, not enzymes. Eliminate D.
• Option E: They are cells (not physical barriers like skin/mucus). Eliminate E.

So the correct answer is A.

Answer:

A. They are both phagocytic cells.
