prophase
anaphase
metaphase
telophase
clear my selection
2 multiple choice 2 points
what is the structure labeled \x\ on the picture?
centriole
spindle
chromosome
chromatid
clear my selection

Explanation:

• Question 1: In anaphase, sister chromatids are pulled apart to opposite poles of the cell. The diagram shows chromosomes (red structures) being separated, which is characteristic of anaphase. Prophase involves chromosome condensation and spindle formation; metaphase has chromosomes aligned at the equator; telophase is the final stage with new nuclear envelopes forming.
• Question 2: Centrioles are cylindrical structures (labeled X) that help organize the spindle fibers during cell division. Spindle is the network of fibers; chromosome is the DNA - protein complex (red structures); chromatid is one half of a replicated chromosome.

Answer:

1. anaphase
2. centriole
