Which of the following is true of meiosis?

• Meiosis produces cells with twice the chromosome number of body cells.

• Meiosis produces somatic cells during the process of binary fission.

• Meiosis is responsible for the growth and repair of tissues.

Animal cells and plant cells carry out the process of cytokinesis differently. Which of the following is a major difference between animal cell and plant cell cytokinesis?

• Animal cells carry out crossing over while plant cells do not.

• Plant cells elongate and form a cell plate at the equator.

• Animal cells lack the centrioles that help plant cells separate their chromosomes.

• Plant cells are divided by a protein belt that shortens until it pinches the cell in half.
