  2. Reflection • Prompt: Write 3 facts that you know about respiration and fermentation.

  3. Cell Cycle ? Interphase Prophase ? ? Cytokinesis Metaphase ? Telophase Anaphase ? ?

  4. Interphase • Stage 1: Interphase: Period before cell division occurs. • Cell is doing its J___ while growing (doubles in size) • Replicates (make a copy) its DNA ob

  5. Mitosis : Prophase Prophase: Identical Chromatids p______. They are held together by a centromere air up

  6. Mitosis : Metaphase Metaphase: Chromosomes line up in the m______ iddle

  7. Mitosis : Anaphase Anaphase: The centromeres split and the chromosomes are pulled a______ part

  8. Mitosis: Telophase Telophase: Each set of chromosomes are F___ away and a nucleus forms around them ar

  9. Cytokinesis Cytokinesis The cell membrane m______ inwards then pinches in two. This form 2 identical cells oves

  10. DNA – Deoxyribonucleic Acid • Nitrogen Based Molecules (4 Letters of DNA Alphabet) • A pairs up with ____ • G pairs up with ____ T C

  11. Cell Cycle • Stage 1: Interphase: Period before cell division occurs. • Cell doubles in size • Copy the DNA in its nucleus

  12. Cell Cycle • Stage 2: Mitosis • One copy of the DNA is distributed into each of the two daughter cells

  13. Cell Cycle • Stage 3: Cytokinesis • Cytoplasm divides

  14. Cell Cycle Facts • Some cells divides every 2 hours or less • Human Liver cells divides every 22 hours • There are about _____ million cells dividing in your body right now!! • Most cells divide but human b_____ cells never divide. 100 rain

  15. Cell Cycle Facts • Some cells divides every 2 hours or less • Human Liver cells divides every 22 hours • There are about 100 million cells dividing in your body right now!! • Most cells divide but human brain cells never divide.
