Question

a photomicrograph of onion root tip cells during mitosis is shown below. which phase of mitosis is occurring in the cell indicated by the arrow? a prophase b metaphase c anaphase d telophase

Explanation:

In anaphase of mitosis, sister - chromatids are pulled apart to opposite poles of the cell. The cell indicated by the arrow shows the separation of chromatids, which is characteristic of anaphase. Prophase involves the condensation of chromatin and the breakdown of the nuclear envelope. Metaphase has chromosomes lined up at the equatorial plate. Telophase is the final stage where the nuclear envelope reforms around the separated sets of chromosomes.

Answer:

C. Anaphase
