Chapter 4 – Tour of the CellSI What are the 3 tenets of the Cell Theory? TODAY! What are the three domains of living things? 2-3 What are the characteristics of prokaryotic cells? How large are prokaryotic cells compared to eukaryotic cells? What characteristics distinguish eukaryotic cells? Can you draw a cell and all of its organelles? Can you explain the basic structure an function of each of the organelles? What are the differences between plant cells and animal cells? 1 Cell Theory The Three Tenets: All living things are made of cells. The cell is the basic structural unit of living things. All cells come from previously existing cells. 2 3 Prokaryotic cells – Domain Bacteria 4 Prokaryotic cells – Domain Bacteria 5 Prokaryotic cells – Domain Archaea 6 Domain Eukarya Size (10-100 µm) Organization Defining characteristics 7 Domain Eukarya 8 Chapter 4 – Tour of the CellSI What are the 3 tenets of the Cell Theory? TODAY! What are the three domains of living things? 12-1 What are the characteristics of prokaryotic cells? How large are prokaryotic cells compared to eukaryotic cells? What characteristics distinguish eukaryotic cells? Can you draw a cell and all of its organelles? Can you explain the basic structure an function of each of the organelles? What are the differences between plant cells and animal cells? 9 Domain Eukarya Membrane-bound 10 Domain Eukarya – let’s draw 11 Cell Wall Cell Membrane 12 Cytoplasm vs. Cytosol 13 Let’s start from the inside… 14 Nucleus 15 Endoplasmic Reticulum 16 There are also free ribosomes in the cytoplasm 17 Ribosomes! 18 Back to a whole cell view… 19 Golgi Body/Golgi Apparatus 20 Vesicles releasing molecules outside the cell 21 Let’s move to organelles that are not part of the internal membrane system 22 Let’s move to organelles that are not part of the internal membrane system 23 Mitochondrion = just one Mitochondria = plural 24 Let’s move to organelles that are not part of the internal membrane system 25 Lysosomes Peroxisomes 26 Cytoskeleton 27 Cytoskeleton Microtubules Microfilaments Intermediate 28 29 Centrioles 30 Vacuoles in Plant and Animal Cells 31 32 33 Chloroplasts 34 On the outside of a cell, for movement cilium/ cilia flagellum / flagella 35 36 Chapter 4 – Tour of the Cell What are the 3 tenets of the Cell Theory?
