Prokaryotes are the largest group of organisms, mostly due to the vast array of bacteria which comprise the bulk of the prokaryote classification. Eukaryotes are generally more advanced than prokaryotes. There are many unicellular organisms which are eukaryotic, but all cells in multi-cellular organisms are eukaryotic. 1.

40. TIMES UP!!!! TIME TO SHARE ANSWERS!

41. ReadAloud—pg 173 Two Basic Cell Types

42. Cells that do not contain internal membrane-bound structures are called prokaryotic cells. The cells of most unicellular organisms such as bacteria do not have membrane bound structures and are therefore called prokaryotes. Two Basic Cell Types

43. A prokaryotic cell does not have internal organelles surrounded by a membrane. Most of a prokaryote’s metabolism takes place in the cytoplasm. 1. Ribosomes 2. DNA 3. Plasma membrane 4. Cell wall Chapter Assessment

44. Cells that do not contain any membrane-bound organelles. Example: bacteria Prokaryotes Take Notes! Topic: Cells

46. Most of the multi-cellular plants and animals we know are made up of cells containing membrane-bound structures and are therefore called eukaryotes. Cells containing membrane-bound structures are called eukaryotic cells. Two Basic Cell Types

47. This eukaryotic cell from an animal has distinct membrane-bound organelles that allow different parts of the cell to perform different functions. 4. Plasma membrane 1. Nucleus 2. Nucleolus 3. Chromosomes 5. Organelles

48. Cells that contain membrane- bound organelles. Examples: amoebas, algae, yeast, animals, plants. Eukaryotes Take Notes! Topic: Cells

50. The membrane-bound structures within eukaryotic cells are called organelles. Each organelle has a specific function that contributes to cell survival. EUKARYOTIC CELLS

51. Human Cell Eukaryotic cells are generally one to one hundred times bigger than prokaryotic cells.

53. Eukaryotes Prokaryotes Both Fill out the diagram using your notes and the text book!!!!

54. Prokaryotes NO membrane- bound organelles cell walls most are unicellular DNA floats freely around small (.001 -.01mm) Both: cytoplasm DNA as genetic material ribosomes Cell membrane CELLS Eukaryotes nucleus & membrane-bound organelles some have cell walls most are multi- cellular large (.01 -.1mm)

71. Get your Biology Book! Responsibilities & Expectations: 1. Keep it in a SAFE place (at home)—DO NOT LOSE IT! *you do not need to bring it to class (for now) unless I tell you to *if it’s lost or stolen you will owe a LOT of money! *Harper teachers/staff will track you down! *You MUST have the same number at the end of the year as the one you get today, in other words, turning in ANY book at the end of the year doesn’t cut it… it MUST BE YOURS! 2. Do not write on it, rip any pages, or damage it in any way 3. USE IT!—Every time you open it up, your grade will improve!
