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 . Cell Increase and Decrease. Cell division increases the number of somatic cells. Consists of mitosis (division of the nucleus) and cytokinesis (division of the cytoplasm). Apoptosis, programmed cell death, decreases the number of cells. 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 . EQ: How do cells divide? . Cell Division . —. . process by which . a cell divides into 2 new cells. Why do cells need to divide? . Living things grow by producing more cells, NOT because each cell increases in size. Means “to move the cell”. Approximately 5% of cell’s life. Process differs in . Heterotrophs. (Animals) . Autotrophs. (Plants) due to presence of cell wall. HETEROTROPHS. AUTOTROPHS. Cell. membrane . Chapter 10. In Your Notebook. Materials move through cells by diffusion. Oxygen and food move . into cells. , while waste products move out of cells. How does the size of . a cell . affect how . efficiently .

The table below compares the length of different cell cycles.. What Are the Functions of Cell Division?. Read the “My Planet Diary: Cycling On”…p. 56. mitosis. results in an increase in number of . identical. cells for . growth and repair. .. Identify and name the stages of mitosis in diagrams and photomicrographs.. Describe the . cell cycle. and relate it to an understanding of . 1. Cell division. Mitosis. Cell division functions in reproduction, growth, and repair. In unicellular organisms, the division of one cell to form two reproduces . an entire . organism (e.g., bacteria, yeast, .
