Reporting Category 1 Cell Structure and Function Station 1 Prokaryotic and Eukaryotic Cells Essential Question – Bell Ringer If two different cells each contain DNA, how can one cell be classified as prokaryotic and the other eukaryotic? In prokaryotic cells, the DNA floats freely inside the cell, whereas in eukaryotic cells, the DNA is bound by a membrane Pre-Review Question • Which of the following organisms could be prokaryotic or eukaryotic? A. Organisms that lack a nucleus that contain genetic material. B. Single-celled organisms. C. Bacteria D. Archaebacteria Pre-Review Question • Which of the following organisms could be prokaryotic or eukaryotic? A. Organisms that lack a nucleus that contain genetic material. B. Single-celled organisms. C. Bacteria D. Archaebacteria Pre-Review Question • Which of the following organelles is not membrane bound? A. B. C. D. E.

Prokaryotic and Eukaryotic Cell Comparison Prokaryotic Cell Structures Eukaryotic Cell Plant Structures Eukaryotic Cell Animal Structures DNA Ribosomes Cell Membrane Cell Wall DNA Ribosomes Cell Membrane Cell Wall Nucleus Golgi Body Mitochondria ER Lysosome Chloroplast DNA Ribosomes Cell Membrane Nucleus Golgi Body Mitochondria ER Lysosome Characteristics of Prokaryotic and Eukaryotic Cells Prokaryotic Cells Some organisms of this cell type produce endospores during extreme conditions. Reproduce only asexually, usually by fission or budding. Exist only as a single-celled organism, some move around using flagellum. Found in organisms that belong to the kingdoms Archeabacteria and Eubacteria. DNA floats freely around. Both Cells Eukaryotic Cells Ribosomes found within the cells Cells’ organelles are surrounded by a membrane. DNA found inside the cell. Found in organisms that belong to the domain Eukaryata. Ten times larger than the other cell type. Exhibit higher levels of division of labor. Some organisms of the cell type are unicellular, others are munlticellular. Cell DNA found within a membrane covered nucleus. I need to remember…….. • Prokaryotic cells do not have a true nucleus. • In eukaryotic cells, the DNA is surrounded by a membrane. • Both types of cells have ribosomes. • Some eukaryotic cells and all prokaryotic cells are surrounded by a cell wall. • Eukaryotic cells have organelles surrounded by membranes. • Prokaryotic cells can reproduce only asexually, by fission or budding. • Eukaryotic cells reproduce asexually and sexually. Post Review Question • What type of cell is this? Prokaryotic • How do you know?
