Cytokinesis starting. *During . its life, a cell passes through a well-ordered series of events known as the . mitosis. and . meiosis. and relate to the processes of . sexual. and . asexual reproduction . and . their . consequences for genetic variation. .. Mitosis and Meiosis. Cell Division. Process by which new cells form from existing cells. Cell Division.

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.. Chapter 8. Asexual vs. Sexual reproduction. Asexual reproduction – new organisms/cells are genetically identical to parent cells/organisms . Sexual reproduction – offspring have a combination of genes from both parents. . 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.

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. . 172BIOLOGY CELL CYCLE AND CELL DIVISION171 The stages through which a cell passes from one division to the next is calledthe cell cycle. Cell cycle is divided into two phases called (i) Interphase
Lecture 4. Mitosis. Mitosis is a part of the . cell cycle process . by which chromosomes in a cell nucleus are . separated into two identical sets of chromosomes. , each in its own nucleus. . In general, . 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..
