Question

which microscope image shows a real plant cell in cytokinesis?

Explanation:

Cytokinesis is the final stage of cell division, where a single cell splits into two distinct daughter cells. Plant cells undergoing cytokinesis will form two separate, enclosed cells (unlike animal cells that form a cleavage furrow). The top-right image shows two distinct, rounded cells, which are the result of a plant cell completing cytokinesis. The other images show chromosomes in mitotic stages (not the final split cells) or a single undivided cell.
