  1. The Cell

  2. Empty slide to keep flashcards in order

  3. What is a Prokaryote? Prokaryote ?

  4. NONucleus or membrane bound organelles. • “Pro” = “No Nucleus” • A single celled organism • DOES have Cell Membrane, DNA(circular type), Ribosomes, Cytoplasm, and Ciliaand/orFlagella Bacteria Cytoplasm Cell Membrane

  5. What is a Eukaryote? Eukaryote ?

  6. What is a Eukaryote?

  7. What MUST all cells have? (Eukaryotes & Prokaryotes) Things

  8. What MUST ALL cells have? (Eukaryotes & Prokaryotes) 4 Things:

  9. Cell Wall • Chloroplasts • Large Vacuole

  10. Name the 3 parts of the Cell Theory Scientists who helped develop the Cell Theory

  11. List the 3 parts of the Cell Theory Cells are the basic unit of life Cells come from existing, living cells All living things are made of 1 or more cells

  12. Who invented the microscope and saw the first living (live) cells in pond water and called them “wee beasties?”

  13. Who invented the microscope and saw the first living cells in pond water and called them “wee beasties?” Leeuwenhoek

  14. Who saw cork and named the chambers “Cells”?

  15. Who saw cork and named the chambers “Cells”? Hooke Sounds like cork (kind of)

  16. What did Schlieden say? What did Schwann say?

  17. What did Schleiden say? What did Schwann say? Schwann claimed that all animals are made of cells. Think: Schwann sounds like Swan the animal Schleiden claimed that all plants are made of cells. Think: Schlidin’ down the vine and vines are plants

  18. Who claimed that all cells must come from existing cells? Hint: Cows come from cows Cells come from cells

  19. Who claimed that all cells must come from existing cells (reproduce)? Virchow “Vircow” Way to Remember: Cows come from cows Cells come from cells

  20. Who did this experiment and believed in biogenesis?

  21. Who did this experiment and believed in biogenesis? Redi - Biogenesis

  22. Who did this experiment and believed in abiogenesis?

  23. Who did this experiment and did he believe in biogenesis or abiogenesis? Needham – Abiogenesis (He needed more information on how to do a good experiment)

  24. Who did this experiment and believed in biogenesis?

  25. Who did this experiment and believed in biogenesis? Pasteur - Biogenesis

  26. What determines the shape of a cell?

  27. What determines the shape of a cell? The cell’s FUNCTION!

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

  29. What are the four levels of cell organization starting from the cell?

  30. White

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

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

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

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

  35. What 3 things pass through the cell membrane or cell wall easily?

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

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

  38. What is located in the cell membrane to selectively allow things into and out of the cell? Proteins & Protein Channels

  39. ?

  40. Cytoplasm

  41. What is the control center of the cell?

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

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

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

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

  46. 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

  47. What is the genetic material that is inside the nucleus called when it is threadlike? What is the genetic material inside the nucleus called when it has condensed and preparing for cell division?

  48. What is the genetic material that is inside the nucleus called when it is threadlike? Chromatin(Hint: looks like spaghetti) What is the genetic material inside the nucleus called when it has condensed and preparing for cell division? Chromosome
