PPT-The Cell Cycle Most organisms go through a cycle of growth, development, and division

Phases of the cell cycle Interphase Mitotic Phase Interphase G1 a cell grows and develops S a cell continues to grow but copies its DNA G2 still growing but begins to store energy and get ready to divide. Section 5.1. 1. Objectives. SWBAT describe the stages of the cell cycle.. SWBAT compare rates of division in different types of cells.. SWBAT identify factors that limit cell size.. 2. Starter. Why do you always have to cut your hair, your fingernails, and the lawn?. Why do cells need to divide?. Growth and development. You started as 1 cell and now you’re made up of roughly 40 TRILLION cells. Repair and regeneration of tissue. Reproduction. What happens when cells divide? . 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 . Why is regulation of the cycle important?. 40%. Approximately 39.6 percent of men and women will be diagnosed with cancer at some point during their lifetime. . (based on 2010-2012 data). (cancer.gov). Unicellular organism- cell division reproduces . an entire . organism. Multicellular. organisms- cell . division . can . produce . growth or progeny. Cell . division functions in reproduction, growth, and repair. How did I grow taller. ?. . How . are my worn out cells replaced. ? . How . do I heal from injuries. ?. The answer is….. Cellular Reproduction . or Mitosis. THE . CELL CYCLE:. Cells go through cycles during their lifetime.. 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. Identify and restate what the phases of the eukaryotic cell cycle are.. Restate what happens in each stage of the cycle.. Vocabulary. Cell . cycle. Interphase. Mitosis. Cytokinesis. Cells . Live in a Cycle. . During the cell cycle, a cell grows, prepares for division, and divides to form two identical daughter cells, each. of which then begins the cycle again.. The series of events that cells go through as they grow and divide.. 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 x All cells are formed by division of pre - existing cells x Each new individual begins its life as a new single cell commonly the fertilized egg or zygote x A large number of cells are being t Multicellular.  organisms, or organisms that are made up of many cells..  . “multi,” meaning . many . Examples of Multicellular organisms: All animals, plants, most fungi. Cells are very small, so you usually need a microscope to see. Unicellular organisms. cell division = reproduction. Multicellular organisms. cell div. needed for development. & for reproduction (meiosis). Mitosis gives each cell. complete set of genetic material. 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 .
