When homologous chromosomes form pairs during prophase I of meiosis I, crossing-over can occur. Crossing-over is the exchange of genetic material between non-sister chromatids of homologous chromosomes. It results in new combinations of genes on each chromosome.

When cells divide during meiosis, homologous chromosomes are randomly distributed during anaphase I, separating and segregating independently of each other. This is called independent assortment. It results in gametes that have unique combinations of chromosomes.

Schach [20]

A.

Animal cells are very close to plant cells, but they have one key difference that separates them; the cell wall.

A cell wall is a thicker layer on the outside of the cell membrane. These are unique, and are <u>only found in plant cells.</u> Animal cells just have the cell membrane as their outer part. This enables them to change shape due to the membrane being very flexible.

Plant cells do not change, and only conform to their cell wall's shape. This enables them to grow up (literally) to help gather sunlight and enable photosynthesis.
