Page 56 Page 56 Page 56 Comparing Cell Cycles The table below compares the length of different cell cycles What Are the Functions of Cell Division Read the My Planet Diary Cycling Onp 56. Cell Division. Key Roles. asexual reproduction. growth. renewal & repair. production of gametes (sperm & egg). mitosis. meiosis. More about DNA. cell division involves the distribution of DNA to daughter cells. Reproduction . and Development. About this Chapter. Sex determination and differentiation. Gametogenesis. and patterns of reproduction. Male reproductive development and physiology. Female reproductive development and physiology. 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 . C8 Cells arise from pre-existing cells, and cell division leads to an increase in cell number. C8.1 explain why the amount of . dna. in a cell doubles before division. Cells contain . Deoxyribose. nucleic acid. 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.. Cell division creates duplicate offspring in unicellular organisms (Asexual Reproduction). Provides for growth, development, and repair in multicellular organisms (Sexual Reproduction). The cell cycle extends from the creation of a new cell by the division of its parent cell to its own division into two cells. Chapter 4: Animal Growth and Heredity. Vocabulary. Life cycle- the stages that a living thing passes through as it grows and changes.. Mitosis- the process by which most cells divide.. Chromosome- A threadlike structure in the nucleus, made up of DNA.. 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 . 1. Cell Division. The ability of organisms to produce more of their own kind is the one characteristic that best . distinguishes living . things . from nonliving . matter.. Cell division . functions in . 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. . 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. Ch. 10: Section 1 . Limits to Cell Growth/Size. DNA “Overload” – If a cell grows too large, its DNA could no longer serve the needs of the entire cell. Exchanging materials – if a cell is too large, is struggles to move enough nutrients & wastes throughout the cell and to the cell membrane. Unicellular organisms. cell division = reproduction. Multicellular organisms. cell div. needed for development. & for reproduction (meiosis). Mitosis gives each cell. complete set of genetic material.
