7th Grade Quiz | Cell Division

What is the cell cycle made up of?

Interphase, Mitosis and Cytokinesis

What happens in Prophase?

Centroile pairs to opposite sides of a cell to prepare.

What happens in Metaphase?

Chromosomes align to the center of the cell.

What happens in Anaphase?

the chromosomes at the centromeres(central part of the cell) begin to split.

What happens in Telophase?

Chromosomes uncoil, being close to making 2 new cells.

What takes place during interphase?

Cell develops, Prepares for mitosis, DNA replication.

Mitosis Results in how many cells when over?

2. Cells.

If the original cell has 36 chromosomes, how many chromosomes are in each cell by the end of mitosis?

36 Cells.

Because cells resulting from mitosis have the full number of chromosomes at the end of the division, they are called what type of cell?

Daughter Cell.

A special cell division known as _____, that takes cells with half the number of chromosomes. This takes place in the reproductive organs only.

Meiosis.

Meiosis results in how many cells when over?

18

Name 3 reasons why cells divide

To produce more cells, cover up injuries and replace dead cells.

A human body has __ chromosomes.

46.

We inherit one of each each type of ______ from our mother and one of each type from our father.

Chromosomes.

During ____, DNA is copied so that each of the two daughter cells get the same genetic information.

Mitosis.

____ is the division of the nucleus. Mitosis has 4 phases: Prophase, Metaphase, Anaphase and Telophase.

Mitosis.

____ is the division of the cytoplasm and organelles resulting in two identical copies of the cell.

Cytokinesis.

Specialized cells in ____ undergo this form of cell division to create sex cells.

Meiosis.

Reproductive cells have ___ of the number of chromosomes of the parent cell.

Half.

Sex cells (gametes) have half of the number of chromosomes of a body cell so when 2 gametes unite, they will form an organism with the ______ number of chromosomes.

Original.
