Mitosis and Meiosis

Human sperm and egg cells have 23 chromosomes.

• True

• False

Cells spend the majority of their lifetime in interphase.

• True

• False

Chromatids separate from each other during telophase.

• True

• False

Plant cells cannot undergo cell division because of their strong cell walls.

• True

• False

The structure that attaches two sister chromatids to each other in a chromosome is called a(n)

• chloropast

• centromere

• gamete

• centriole

The phase of mitosis that is characterized by the arrangement of all chromosomes along the equator of the cell is called

• telophase

• metaphase

• anaphase

• prophase

The cell shown in diagram 5 is in

• metaphase

• telophase

• anaphase

• prophase

As a result of mitosis, each of the two new cells produced from the original cell during cytokinesis

• receives a few chromosomes from the original cell.

• receives an exact copy of all the chromosomes present in the original cell

• donates a chromosome to the original cell

• receives exactly half the chromosomes from the original cell

In plant cells, cytokinesis occurs when

• the chromosomes make exact copies of themselves

• spindle fibers are formed

• a cell plate forms

• osmotic pressure is too low

The process by which a cell divides into two daughter cells is called

• cell division

• metaphase

• interphase

• synthesis
