23. Partner Read Prokaryotes are unicellular organisms, found in all environments. 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. ReadAloud—pg 173 Two Basic Cell Types

41. Two Basic Cell Types 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.

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

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

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

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

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

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

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