EUKARYOTIC CELLS Content Standard: The learners demonstrate an understanding of prokaryotic and eukaryotic cells Performance Standard The learners shall be able construct a 3D model of a plant/animal/ bacterial cell using recyclable materials 3D ANIMAL CELL MODEL 3D BACTERIAL CELL MODEL 3D PLANT CELL MODEL Before we can move forward, you need to know... ▪ All organisms (living things) are made of cells ▪ Most of the organisms you are familiar with are multicellular-made up of many cells. ▪ However, some organisms can be unicellular- made up of only one cell. Its entire body is just one super tiny cell! ▪ Prokaryotes (prokaryotic) or ▪ Eukaryotes (eukaryotic) Cells fall into one of two categories… And that is it! Every organism on the planet can be put into one of these two categories, including you! Pro means BEFORE / NO Prokaryotes: unicellular microorganisms lack a distinct nucleus lack membrane-bound organelles very simple and small Prokaryotes: Eu means True Eukaryotes: ▪ unicellular or multicellular organisms ▪ have a nucleus ▪ have membrane-bound organelles ▪ LARGER and more complex ▪ Examples: animals, plants, fungi and protists  Like the organs in your body, each organelle in the cell performs a Eukaryotes: specific function that helps the cell maintain homeostasis: a state of balance. Eukaryotes: Prokaryotes are much smaller than Eukaryotes Prokaryote (Bacteria) Eukaryote (Animal Cell) Prokaryote: Eukaryote: Lacks Nucleus Has Nucleus Organelles Lack Organelles have Membranes Membranes DNA is in the Nucleus DNA is free floating Can be unicellular or unicellular multicellular bacteria Plants, Animals, Fungi, Smaller than Eukaryote Protists Reproduction is asexual Much Larger than Prokaryote (exact copies/clones) Reproduction can be asexual (clones) or sexual (variations) COMPLETION ACTIVITY: Complete the phrase below. The words prokaryotic and eukaryotic must be used: All cells are not the same because… 24
