Question

question 1-48
which of the following occurs during cell division in a plant cell but not in an animal cell?
the cell plate forms.
the spindle fiber forms.
the centrioles migrate to opposite poles of the cell.
the chromosomes line up along the equator of the cell.

Explanation:

To solve this, we analyze each option:

• "The cell plate forms": Plant cells form a cell plate during cytokinesis (cell division's final stage) to create a new cell wall. Animal cells form a cleavage furrow instead, so this is unique to plant cells.
• "The spindle fiber forms": Both plant and animal cells form spindle fibers during mitosis/meiosis.
• "The centrioles migrate to opposite poles": Plant cells lack centrioles (or have different structures), while animal cells use centrioles for spindle formation. So this is unique to animal cells, not plant.
• "The chromosomes line up along the equator": Both plant and animal cells have chromosomes align at the metaphase plate (equator) during metaphase.

So the correct option is the one stating "The cell plate forms."

Answer:

The cell plate forms. (Assuming the first option is labeled, e.g., A. The cell plate forms, then the answer would be A. The cell plate forms)
