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 eg bacteria yeast . 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 . 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. 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. 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. 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 . 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. 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. . 1. 2. Peroxisomes. Peroxisomes. = Membrane-bound organelles that contain specialized teams of . enzymes . for . specific metabolic pathways; all contain . peroxide-producing . oxidases. .. • Bound by a single membrane. Acknowledgement. I would like to express special thank of gratitude to our respected principal madam, Mrs. . Kuljit. . Kaur. , for giving us this unique opportunity to express ourselves in a creative way. 1. A TOUR OF THE CELL. The . Nucleus. Nucleus. = A generally conspicuous membrane-bound cellular organelle in a . eukaryotic . cell. ; contains most of the genes that control the entire . cell. Nuclear envelope . Page 56. Page 56.
