Explanation:

To solve this, we analyze each option:

• Option A (vacuoles): Animal cells have vacuoles (smaller), so not unique to plant cells.
• Option B (cell wall): Plant cells have a cell wall for structure/support; animal cells do not.
• Option C (nucleus): Both plant and animal cells have a nucleus.
• Option D (cell membrane): Both plant and animal cells have a cell membrane.

So the structure unique to plant cells (not in animal cells) is the cell wall.

Answer:

B. cell wall
