Mitosis/Meiosis Review

Label the following pictures

prophase

telophase

anaphase

metaphase

interphase

List the stages of mitosis in order.

Interphase Prophase Metaphase Anaphase Telophase

Identify what phase of mitosis is being described. Chromosomes separate to opposite ends. Chromosomes have doubled and the nuclear membrane is fading. Cytophasm starts to divide into two cells.

Anaphase Prophase telophase

Identify what phase of mitosis is being described. 4. Cell is growing and daily activities occur. 5. Chromosomes line up in the center of the cell.

4. Interphase 5. metaphase

The total number of cells in an organism increases as a result of Photosysthesis Cell division Fermentation respiration

Cell division

The formation of a cell plate is a characteristic of _________ Cytokinesis in plant cells Cytokinesis in animal cells Both a and b Neither a or b

Neither a or b What phase is it??? It is TELEPHASE

TRUE OR FALSE Cell divisions allow organisms to grow, repair damages structures, and produce energy.

FALSE GROW, REPAIR AND REPRODUCE

TRUE OR FALSE Mitosis results in the formation of two daughter cells.

TRUE

TRUE OR FALSE The process in which the cell makes an exact copy of the DNA in its nucleus is replication.

TRUE

TRUE OR FALSE Cell growth and production of new organelles and enzymes are characteristics of prophase.

FALSE Interphase

TRUE OR FALSE Body cells of humans have 46 pairs of chromosomes.

FALSE 23 pairs!

TRUE OR FALSE Sex cells have twice the number of chromosomes as body cells.

FALSE Sex cells have HALF the number of cells that a body cell has.

TRUE OR FALSE Genes pass from parents to offspring on chromosomes.

TRUE

TRUE OR FALSE The two chromosomes in a pair having the same genes lined up in the same order, with the exception of the male sex chromosome.

TRUE

TRUE OR FALSE A fertilized egg has twice the number of chromosomes as the body cells of the parent.

FALSE

Which stage of the cell cycle usually lasts the longest?

interphase

The process that produces sex cells is? mitosis or meiosis

meiosis

Tell how plant mitosis is different than animal mitosis

1. Plant cell has a cell plate 2 1. Plant cell has a cell plate 2. Plant cell divides from inside out and an animal cell divides from outside in.
