Question

microfilaments allow cell to change shape that is needed during mitosis. chromosome chromatid

Explanation:

Chromosomes are structures within cells that contain DNA and associated proteins. During cell division (mitosis or meiosis), chromosomes condense and become visible. A chromatid is one of the two identical halves of a replicated chromosome. Before cell division, each chromosome replicates, forming two sister chromatids joined at the centromere.

Answer:

Chromosome: Carries genetic information, condenses during cell division.
Chromatid: One half of a replicated chromosome, joined at centromere.
