1. Semester 1, Day 2 Cells

2. Agenda  Turn in Cornell Notes & Question Responses  Macromolecules Quiz  Cells Lecture  Cells Practice  4 Minute Break  Reading/Work Time  Hand Quizzes back and review

3. Turn in Cornell Notes and Question Responses  Order  Cornell Notes 5.1  Cornell Notes 5.2  Cornell Notes 5.3  Cornell Notes 5.4  Cornell Notes 5.5  Responses to Section 5.1-5.5 and Chapter 5 Review  Make sure that your name is on your notes/responses  Initial each following page  Keep the papers together, fold the corner if not stapled

4. Macromolecules Quiz  Complete the quiz silently  When you are finished, place quiz facedown on desk  When everyone is finished, pass quizzes foward

5. Cells  Levels of Organization  Cells: A. All life has ≥1 cell(s) B. Basic unit of life (anything before not living) C. Cells come from living cells AtomsMoleculesMonomersMacromolecules/ Polymers CellsOrganisms

6. Cells Prokaryotic Single Cell No Nucleus Simple Eukaryotic Single or Multicellular True Nucleus Complex Bacteria Early life Found almost everywhere Archaea Extreme conditions (salt, heat, no oxygen) Animal Multicellular Digest their food Can move independently Plant Multicellular Photosynthesis for food Rigid cell walls Chloroplasts Fungi Mostly multicellular Rigid cell walls Consume dead matter Protist Mostly unicellular Don’t fit in, but plant-like, animal- like, or fungi-like

7. Cells  Prokaryotic Cells (Bacteria, Archaea) Ribosome - Makes proteins Capsule - Additional Protection Cell Wall - Rigid Shape Plasma/Cell Membrane -Encloses cell -Regulates entrance & exit of substances Flagellum (pl. Flagella) - Movement *Any cell part is called an “organelle” Pilus (pl. Pili) - Attach to other bacteria Nucleoid (DNA) - NO membrane around DNA Cytoplasm -Gel-like fluid

8. Cells  Eukaryotic (Animal, Plant, Fungi, Protist) Centrioles -Organize cell during division Rough Endoplasmic Reticulum -Transports & folds proteins Golgi Apparatus -Packages macromolecules to be shipped out of cell Vacuole (Animal) -Store food, water, waste & minerals (small) Smooth Endoplasmic Reticulum -Lipid Synthesis Mitochondrion (pl. Mitochondria) -Provides energy Flagellum (sometimes) Peroxisome -Breaks down fatty acids Cytoplasm Lysosome -Enzymes breakdown macromolecules Cytoskeleton -Structure & internal movement Plasma/Cell Membrane Ribosomes

9.  Zoom-In on Nucleus Nucleus -Regulates all cell activity -Membrane bound -Contains DNA Cells Nuclear Pore -Exchange materials Nucleolus -Synthesizes ribosomes Nuclear Envelope -Encloses DNA

10. Cells  Eukaryotic (Animal, Plant, Fungi, Protist) Plasmodesmata -Transport & communication b/twn cells Vacuole (Plant) -Store food, water, waste, & minerals (large) Peroxisome Mitochondrion Rough ER Smooth ER Ribosomes Plasma/Cell Membrane Cell Wall -Rigid shape, prevents bursting from too much water Nucleus -Nucleolus -Nuclear Pore -Nuclear Envelope Chloroplast -Use sunlight to synthesize sugar (photosynthesis) CytoskeletonCytoplasm

11. Practice  Split paper into 4 columns  Under “Cell”, indicate if it is prokaryotic, eukaryotic (animal), or eukaryotic (plant) OrganelleFunctionPictureCell

12. 4 Minute Break  Stay on this floor, otherwise privilege will be revoked  Be back in the class by ______.

13. Reading / Work Time  Read Chapter 7  Do the Chapter 7 Assessment Questions #1-17, 19-29  Come show me reading notes when you are finished.

14. Quiz Review

15. Textbooks  If you need a textbook to finish today’s work, please come check out the textbook with Mrs. Larkin
