PPT-CELL DIVISION According

to the cell theory all cells come from preexisting cells Why when and how cells divide is the subject of this unit   Reproduction Cells reproduce in order to make new cells A bacterium divides to become two bacteria. Meiosis. Meiosis occurs in sexual reproduction when a diploid germ cell produces four haploid daughter cells that can mature to become gametes (sperm or egg).. Meiosis. . Goal: reduce genetic material by half. 2.5.1: Cell . Cycle: Outline the stages of the cell cycle, including . interphase. (G1, S, G2), mitosis and . cytokinesis. Cytokinesis starting. *During . its life, a cell passes through a well-ordered series of events known as the . Cytokinesis. 01-08-09. http://www.cellsalive.com/mitosis.htm. Cell Division. The division of eukaryotic cells occurs in two main stages. Mitosis is the first stage. Is the process by which the nucleus of the cell is divided into two nuclei, each with the same number and kinds of chromosomes as the parent cell. Part 1. Meiosis. Types of Cell Division. There are two types of normal cell division – mitosis and meiosis. . Both . types of cell division take place in eukaryotic . organisms. . Mitosis . is cell division which begins in . Mitosis.

If extra copies of DNA are not made, an “information crisis” would occur. The cell also has more trouble moving nutrients and wastes across the cell membrane. ANA 205. 2. Differentiation. - development of a fertilized egg cell to form a complex, multicellular organism involving cellular replication, growth and progressive specialization for a variety of functions. .
