  1. The Cell

  2. What is a Prokaryote? Prokaryote ?

  3. Prokaryotes DO NOT have: • Nucleus • Membrane Bound Organelles • Prokaryotes DO have: • Cell Membrane • Cell Wall (not like plant’s cell wall) • Cytoplasm • DNA (genetic material) • Ribosomes • Flagella / Cilia Remember: Bacteria are Prokaryotes Cilia Cytoplasm Flagella Cell Membrane

  4. What is a Eukaryote? Eukaryote ?

  5. Eukaryotes Plants Protista Animals Fungi • Eukaryotes DO have: • Nucleus • Membrane Bound Organelles (Mitochondria, E.R., Golgi, etc.)

  6. What must ALL CELLS have? (Eukaryotes & Prokaryotes) Things

  7. What must ALL CELLS have? (Eukaryotes & Prokaryotes) 4 Things:

  8. Cell Wall • Chloroplasts • Large Vacuole

  9. Name the 3 parts of the ModernCell Theory

  10. 3 parts of the ModernCell Theory • Cells are the basic units of structure and function in all living things • All cells contain specialized structures (organelles) to perform functions necessary for life • All organisms are made of one or more cells and come from other cells by reproduction

  11. Who invented the microscope and saw the first living (alive) cells in pond water and called them “wee beasties?” (Hint: “Wee” sounds like beginning of his last name)

  12. Who invented the microscope and saw the first living cells in pond water and called them “wee beasties?” Leeuwenhoek “Lee” sounds like “Wee”

  13. Who saw cork and named the chambers “Cells”? Hint: His name rhymes with “cork”

  14. Who saw cork and named the chambers “Cells”? Hint: His name rhymes with “cork” Hooke

  15. What did Schleiden say? What did Schwann say?

  16. What did Schleiden say? What did Schwann say? Schwann claimed that all animals are made of cells. Think: Schwann sounds like swan Schleiden claimed that all plants are made of cells. Think: Schlidin’ down the vine

  17. Who claimed that all cells must come from existing cells by reproduction? Hint: His name sounds like “cow” Cows come from cows Cells come from cells

  18. Who claimed that all cells must come from existing cells by reproduction? Virchow “Vircow” Hint: His name sounds like “cow” Cows come from cows Cells come from cells

  20. Who did this red meat experiment and believed in biogenesis? Redi For Biogenesis No Growth No Growth

  21. Who did this experiment and believed in abiogenesis? Heated (not boiled) Broth Hint: He needed more information on how to do a good experiment!!!

  22. Who did this experiment and believed in abiogenesis? Needham – Abiogenesis (He needed more information on how to do a good experiment) Heated (not boiled) Broth

  23. Who did this experiment and believed in biogenesis? S-shaped flask

  24. Who did this experiment and believed in biogenesis? Pasteur - Biogenesis S-shaped flask

  25. What determines the shape of a cell? Nerve Cells Blood Cells Muscle Cells

  26. What determines the shape of a cell? The cell’s FUNCTION Muscle Cells Blood Cells Nerve Cells

  27. What are the four levels of cell organization starting from the smallest to largest?

  28. What are the four levels of cell organization starting from the cell? make up make up make up

  29. White

  30. What is the semi-permeable membrane, phospholipid bilayer that regulates what goes in and out of a cell?

  31. What is the semi-permeable membrane, phospholipid bilayer that regulates what goes in and out of a cell? Cell Membrane

  32. What is the hard covering of the plant cell that provides support and protection for the plant cell?

  33. What is the hard covering of the plant cell that provides support and protection for the plant cell? Cell Wall

  35. What 3 things pass through the cell membrane or cell wall easily? Carbon Dioxide By Diffusion H2O By Osmosis Oxygen By Diffusion

  36. What is located in the cell membrane to selectively allow larger things into and out of the cell? ?

  37. What is located in the cell membrane to selectively allow larger things into and out of the cell? Protein in Protein Channels

  38. ???????

  39. Cytoplasm cyto = cell plasm = fluid

  40. What is the control center (brain) of the cell?

  41. What is the control center (brain) of the cell? NUCLEUS

  42. What is the organelle that is inside the nucleus and makes ribosomes?

  43. What is the organelle that is inside the nucleus and makes ribosomes? Nucleolus

  44. What covers the outside of the nucleus and what are the holes called to allow ribosomes and RNA out?

  45. What covers the outside of the nucleus and what are the holes called to allow ribosomes and RNA out? Nuclear Membrane (Nuclear Envelope) and Nuclear Pores

  46. What is the genetic material “Blueprints” that is inside the nucleus?

  47. What is the genetic material “Blueprints” that is inside the nucleus? CHROMOSOMES

  48. What organelle is the powerhouse of the cell and found in all Eukaryotes (Plants, Animals, Fungi, Protista) Hint: Think Mighty Mouse who has lots of power!!!!!!
