Control the activities of the cell and facilitate cell division. Chapter 2.2. McGraw-Hill Ryerson. Biology 12. (2011). Concentration gradient. Concentration gradient. : difference in concentration between one side of a membrane and the other. Ions and molecules like to move from . 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 . Mitosis. History . of Understanding Cancer. Rudolf Virchow (1821-1902) – First to recognize leukemia in mid-1800s, believing that diseased tissue was caused by a breakdown within the cell and not from an invasion of foreign organisms.. 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. The Nucleus: the gene-containing control center of the cell.. The nucleus is bound by a double membrane called the . nuclear envelope. . . Inside the nucleus are one or more small, dark-staining, essentially round structures called . Chapter 10. Limits to Cell Size. Cells grow as the organism grows.. However cells only grow to a certain extent then divide. Why?. . - The larger the cell the more demands on its . dna. . - a large cell has more trouble moving food in and waste out. 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 . CHROMOSOME AND CELL DIVISION Despite the diversity among cells, three basic features are common to all cell types. All cells have outer boundary, an interior substance and a control region. CELL STRUCTURE AND FUNCTION Chapters 12, 13, 16, 17. Limits to Cell Growth. The larger a cell becomes, the more demands a cell places on its DNA. 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. Warm-Up.
