Question

which structure helps animal cells organize chromosomes during cell division, but is not found in plant cells? centrioles cell wall chloroplast vacuole

Explanation:

To solve this, we analyze each option:

• Centrioles: In animal cells, centrioles help organize chromosomes during cell division (form spindle fibers). Plant cells lack centrioles.
• Cell wall: Present in plant cells (provides structure), absent in animal cells. Not related to chromosome organization in animal cells.
• Chloroplast: Found in plant cells (for photosynthesis), absent in animal cells. Not involved in chromosome organization.
• Vacuole: Larger in plant cells (stores substances), present in animal cells too (smaller). Not related to chromosome organization in cell division.

So the correct option is the one with centrioles.

Answer:

A. centrioles
