Prokaryotic and Eukaryotic Cells 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? Nucleus Smooth endoplasmic reticulum Rough endoplasmic reticulum Golgi bodies Ribosomes

Pre-Review Question Which of the following organelles is not membrane bound? Nucleus Smooth endoplasmic reticulum Rough endoplasmic reticulum Golgi bodies Ribosomes

Lab Activities You will now go to the lab and complete the activities for today’s topics.

Prokaryotic and Eukaryotic Cell Comparison Prokaryotic Cell Structures Eukaryotic Cell Plant Structures Eukaryotic Cell Animal Structures DNA Ribosomes Cell Membrane Cell Wall Nucleus Golgi Body Mitochondria ER Lysosome Chloroplast

Characteristics of Prokaryotic and Eukaryotic Cells Prokaryotic Cells Both Cells Eukaryotic 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. Ribosomes found within the cells DNA found inside the cell. Cells’ organelles are surrounded by a membrane. 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? Prokaryotic No nuclear membrane & No membrane bound organelles

Post Review Question Can the following structures be found in both prokaryotic and eukaryotic cells? True Nucleus Cell Membrane Cell Wall Mitochondria Ribosomes No Yes Yes No Yes

Post Review Question Identify which type of reproduction is used by prokaryotic cells, eukaryotic cells or both? Budding Asexual Sexual Binary Fission Prokaryotes Both Eukaryotes Prokaryotes
