Document Summary

Chapter 9 learning objectives: understand the 3 characteristics of cell division, ---cell division is the process in which the genetic information of a cell is passed along to the next generation of cells. Involves the division of a parent cell into 2 daughter cells. Equal distribution of dna to opposite ends of the dividing cell. Separation into two daughter cells: know the 3 stages of interphase, and what happens during each. During the cell cycle interphase alternates with mitosis (a. k. a. Interphase is the period of the cell cycle when the cell is not dividing) Interphase makes up about 90% of the cell cycle. Cell division consists of nuclear division and cytoplasmic division. During this process the dna is equally distributed into 2 daughter nuclei: know the difference between mitosis and cytokinesis, mitosis is the division of the nucleus, -during this process the dna is equally distributed into 2 daughter nuclei.

Related Questions

Describe the process of mitosis and cytokinesis. Your answer should provide specific
information on: 1) the primary events that occur during interphase, specifically those that take
place to prepare a cell for mitotic division; 2) the specific stages of mitosis and the events that
occur in each stage; 3) the primary events during cytokinesis in plant and animal cells as the
content of the cytoplasm is divided between the daughter cells.

What follows G2 phase in a gamete cell?

MITOSIS

Number of chromosomes in the parent cell.

Number of chromatids in the parent cell.

Number of chromosomes in the daughter cell.

Number of chromatids in the daughter cell.

How many daughter cells are produced?

Are the daughter cells haploid or diploid?

How many cell divisions take place?

In what type of cell does this division occur?

Meiosis 1:

Number of chromosomes in the parent cell.

Number of chromatids in the parent cell.

Number of chromosomes in each Meiosis I daughter cell.

Number of chromatids in each Meiosis I daughter cell.

Are the daughter cells haploid or diploid at the end of Meiosis 1?

Meiosis II:

Number of chromosomes in the âparentâ cell (which is a daughter cell from Meiosis I).

Number of chromatids in the âparentâ cell.

Number of chromosomes in each Meiosis II daughter cell.

Number of chromatids in each Meiosis II daughter cell.

Are the daughter cells haploid or diploid at the end of Meiosis II?

Which phase or phases of Meiosis account for the genetic variability among the daughter cells? Howâ¦ what happens in this phase to create the diversity?

Comparing Mitosis and Meiosisâ¦..

How many daughter cells result from Mitosis? Are they diploid or haploid?
