Question

the following micrograph shows onion root cells in various stages of mitosis. one of the cells is labeled with an arrow. the labeled cell shows chromosomes that have separated and are moving to opposite ends of the cell. which stage of mitosis is occurring in the labeled cell? choose 1 answer: a prophase b metaphase c anaphase

Explanation:

To determine the mitosis stage, recall the key events of each stage:

• Prophase: Chromosomes condense, nuclear envelope breaks down.
• Metaphase: Chromosomes align at the cell equator.
• Anaphase: Sister chromatids (chromosomes) separate and move to opposite poles (ends) of the cell.

The labeled cell has chromosomes moving to opposite ends, matching Anaphase’s definition.

Answer:

C. anaphase
