Cell Structure and Function Prokaryotic vs. Eukaryotic Cells Prokaryotic and Eukaryotic Cells All cells have two characteristics in common: They are surrounded by a cell membrane. They contain DNA. All cells fall into two broad groups, depending on whether or not they contain a nucleus. Prokaryotic Cells Eukaryotic Cells Prokaryotic Cells Prokaryotic cells do NOT have… … a nucleus or organelles. Prokaryotic cells are generally smaller and simpler than eukaryotic cells. Bacteria are prokaryotic cells. Prokaryotic Cell Structure All prokaryotes have a cell membrane surrounding their cell Some prokaryotes even have a thick cell wall Prokaryotic Cell Sturcutre Some prokaryotic cells have long, whip-like projections called flagella which allow the cell to move. Another type of projection that prokaryotes can have are called cilia which are shorter projections that are also used for movement. There are even some animal cells that have cilia and flagella • Example: human lungs cells have cilia that help to move mucus. Prokaryotic Cell Structure Prokaryotes do NOT have a nucleus, instead their DNA floats in the cytoplasm Prokaryotic DNA is also circular Prokaryotes do need proteins to live so they do contain _____________ which are the site Ribosomes of protein synthesis Eukaryotic Cells Eukaryotic cells are generally larger and much more complex than prokaryotic cells. Eukaryotic cells have: A true nucleus and organelles. There are two types of eukaryotic cells: plants and animal cell Eukaryotic cells contain a nucleus which holds DNA in the form of chromosomes. Prokaryotic Cells vs. Eukaryotic Cells Prokaryotic Cell Simple or Complex: Uni or multicellular? Size of Cells Nucleus? Organelles? Ribosomes? Form of DNA? Examples: Eukaryotic Cell Cell Component Cytoplasm Cytoskeleton Nucleus Nucleolus Ribosomes Smooth Endoplasmic Reticulum Rough Endoplasmic Reticulum Golgi Apparatus Function Prokaryote Bacteria Eukaryotes Plants Animals Mitochondria Lysosomes Central Vacuole Chloroplasts Cell wall Cilia Flagella Disease Causing Prokaryotes Jigsaw Bacteria Copy the following chart on a piece of paper: Disease it Causes? Symptoms of Disease? How is the Treatment Disease Spread?
