Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the cell type?Eukaryotic cells
2. What is the primary function?Cellular reproduction for growth, tissue repair, and asexual reproduction
3. How does a cell grow before it divides?Before mitosis, a cell goes through interphase with three parts: G1 where it grows and makes proteins, S where it copies its DNA, and G2 where it prepares more proteins for division.
4. What happens during the four stages of mitosis?In prophase, chromosomes become visible and the cell’s nucleus breaks down. In metaphase, chromosomes line up in the middle. In anaphase, sister chromatids separate and move to opposite ends. In telophase, new nuclei form and the cell starts to split into two.

Mitotic Spindle: A structure made of microtubules that segregates chromosomes during mitosis.
Kinetochore: A protein structure on chromatids where the spindle fibers attach during cell division.
Cytokinesis: The division of the cytoplasm to form two separate daughter cells.
