Cell Division

Cell Division. Big Idea: Organisms grow, reproduce, and maintain themselves through cell division. All living things are made of cells. Cells are the most basic unit of life. The study of life. All living things must!!. Made up of cells. Reproduce. Grow/ Change. Obtain and have energy.

  1. Cell Division Big Idea: Organisms grow, reproduce, and maintain themselves through cell division

  2. All living things are made of cells • Cells are the most basic unit of life

  3. The study of life

  4. All living things must!! Made up of cells Reproduce Grow/ Change Obtain and have energy Respond/ adapt to the environment Eliminate waste Move

  5. Cell Theory • All organisms are made up of one or more cells • The cell is the basic unit of life • All cells come from other living cells

  6. Words to Know The duplicated chromosome consists of two chromatids held together by a centromere DNA becomes compacted with chromosomes chromatid DNA (deoxyribonucleic acid: genetic material that is found in all living things Chromosomes: DNA and protein combined as chromatin Centromere: where two identical sister chromatids stay in contact Chromatid: ½ of 2 identical copies of replicated chromosomes replicated copies of a chromosome. Chromatin: the material of which the chromosomes of organisms other than bacteria are composed • It consists of protein, RNA, and DNA Centromere DNA is the genetic material DNA wraps around the protein

  7. Chromatid: ½ of 2 identical copies of replicated chromosomes

  8. DNA (deoxyribonucleic acid: genetic material that is found in all living things Chromosomes: DNA and protein combined as chromatin Centromere: where two identical sister chromatids stay in contact Chromatid: ½ of 2 identical copies of replicated chromosomes Chromatin: the material of which the chromosomes of organisms other than bacteria are composed • It consists of protein, RNA, and DNA

  9. Cell Division • It is the process of one cell dividing into two identical cells. • Fun Fact: Over 2 trillion divisions occur in average human body everyday!

  10. Cell Division • Cell division occurs in all organisms.

  11. Cell Division • Process which new cells are made. They make new cells to grow and replace dead ones. • It is involved in growth, development, and repair • Three types: binary fission, mitosis, and meiosis • All cells divide but only eukaryotes cell undergo mitosis

  12. Cell division is involved in growth, development, and repair. • Growth: Cells are always dividing and making more • Development: Cells become specialized to perform particular functions • Repair: Make new cells for the damaged ones

  13. Everything has a cycle All living things, grow, reproduce, and die called a life cycle

  14. Cell Cycle • Series of events that take place in an eukaryotic cell between its formation and the moment it replicates itself • It’s a sequence of three stages which a cell passes one stage to the next • Three Stages: Interphase, Mitosis, and Cytokinesis • So… a sequence of phases of the life of the cell

  15. Why is it important?

  16. Cell cycle has two main parts • Interphase: cell carries out the function and growth • Mitosis/ Cytokinesis: cell divides • All cells divide but only eukaryotes undergo mitosis

  17. The cycle

  18. The 5 Cycles

  19. Interphase • It is the longest part of the cycle • It has 3 stages • The cell is growing and replicating the chromosomes
