PPT-Cell Unit III: Cell Division, Cell Cycle, Transcription and Translation

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. Cell Increase and Decrease. Cell division increases the number of somatic cells. Consists of mitosis (division of the nucleus) and cytokinesis (division of the cytoplasm). Apoptosis, programmed cell death, decreases the number of cells. 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?. A Chromosome and Sister Chromatids. Key Points About Chromosome Structure. A . chromosome consists of DNA that is wrapped around proteins (. histones. ) and condensed. Each . histone. and the DNA wrapped around it make up a . 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? . &. Cellular Division. I. Cell Division:. . All . cells. are derived from preexisting cells (Cell Theory) . Cell division . is the process by which cells produce new cells . I. Cell Division:. . 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 . Topic 1: DNA Organization. By the end of this topic, you should be able to…. Identify parts of a chromosome. Explain why DNA has to copy and coil before cell division. Explain why cells cannot continue to grow forever. 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.. Cell Cycle - a cycle of growth, development, and division. This is how organisms grow, produce new cells, and replace old cells. The cell cycle occurs in 2 phases: Interphase and . Mitosis. The Cell Cycle: Interphase. 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. It is the growth and division of single cell into daughter cells and duplication (replication).. In . prokaryotic cells, . the cell cycle occurs via process termed binary fission.. In . eukaryotic cells, . 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 On”…p. 56.
