CLIP A Introduction – 45 to 60 seconds Visual Audio <image> All living things are composed of cells. http://pixabay.com/en/landscape-treesunset-559434/ <image> As we already know, the arrangement of cells are responsible for the structure and function of a living organism. http://pixabay.com/en/root-tree-roothanalei-kauai-276446/ <image> Specialized cells in multicellular organisms allow functions such as walking to occur. http://pixabay.com/en/feet-lady-walkingsandles-female-538245/ <image> We know this because scientists have conducted research on cells using microscopes. http://pixabay.com/en/laboratory-scientistsresearch-385349/ <image> Have you ever wondered what a cell looks like up close? http://pixabay.com/en/hela-cells-bacteriagerms-virus-544318/ <image> Under magnification, many parts, or organelles, of a cells can be seen. http://commons.wikimedia.org/wiki/File:Hu man_embryonic_stem_cell_colony_phase.j pg <image> The organelles responsible for cellular structure are the cell membrane, cytoplasm, and cell wall. http://commons.wikimedia.org/wiki/File:Bre ast_cancer_metastasis_to_liver.jpg Question for Clip A Stem: Which of the following answers is NOT an organelle responsible for the structure of the cell? Answers for Question A A. Cell Membrane B. Cell Wall C. Cytoplasm D. Chloroplast Correct Response D Correct – Go to Clip B Incorrect – Go to Clip E CLIP B <image> http://en.wikipedia.org/wiki/File:Algaeconju gate.jpg Build on Introduction – 25 to 35 seconds Cells can be separated into two categories. Plant and Animal. <image> Both plant and animal cells have cell membranes and cytoplasm. http://pixabay.com/en/butterfly-leaf-animanature-plants-404731/ <image> However, only plant cells have cell walls. http://pixabay.com/en/grass-blades-ofgrass-nature-meadow-383284/ <image> Animal cells are often circular and squishy, whereas plant cells are square and rigid. http://commons.wikimedia.org/wiki/File:Sto mach_cells_that_are_non-malignant.jpg Question for Clip B Stem: Which of the following is NOT found in an animal cell? Answers for Question B A. Cell Membrane B. Cell Wall C. Cytoplasm D. Chloroplast Correct Response B Correct – Go to Clip C Incorrect – Go to Clip F CLIP C Build on Clip B – 25 to 35 seconds Visual Audio <image> Cell membranes are found in both animal and plant cells. www.morguefile.com/archive/display/9185 72 <zoom in towards door> <image> Cell membranes, sometimes referred to as plasma membranes, act like screen doors by selecting what comes in and out of the cell. http://www.morguefile.com/archive/display/ 125681 <image> http://pixabay.com/en/vegetables-colanderchopped-washing-14702/ This selectiveness is known as permeability. <image> We call a cell membrane selectively permeable because only specific things go through the membrane. http://www.morguefile.com/archive/display/ 807712 Question for Clip C Stem: Which of the following answers describes the cell membranes selectively permeable nature? Answers for Question C A. Allows specific liquids and gases to flow through the membrane. B. Allows all substances to flow through the membrane. C. Allows only solids to pass through into the cell. D. Allows nothing to pass through the membrane into the cell. Correct Response A Correct – Go to Clip D Incorrect – Go to Clip G <image> CLIP D Build on Clip C – 25 to 35 seconds Visual Audio Cell walls, only found in plants, are very rigid. http://pixabay.com/en/sunflower-flowersbright-yellow-448654/ <image> This rigid outer layer provides additional protection for the cell. In plants, the cell membrane is found right underneath the cell wall and has the same function. http://pixabay.com/en/armor-knight-middleages-401699/ <image> Cytoplasm, found in both plant and animal cells, is a clear gel like fluid that gives the cell its shape. http://commons.wikimedia.org/wiki/File:Cub ic_phase_gel.jpg <image> Cytoplasm also allows substances to flow through it to various parts of the cell. http://pixabay.com/en/splashing-splashaqua-water-rain-165192/ Question for Clip D Stem: Which of the following cell structures provides a rigid outer layer to plant cells? Answers for Question D A. Cell Wall B. Cell Membrane C. Cytoplasm D. Chloroplast Correct Response A Correct - Success Alert Incorrect – Go to Clip H CLIP E Remediation for Clip A – 25 to 35 seconds Visual Audio <image> http://www.morguefile.com/archive/display/ Cells are the essential building blocks of all living organisms. 899572 <image> Cells give organisms their shape, and allow them to conduct functions necessary to survive. http://pixabay.com/en/sea-turtle-babyyoung-survival-356125/ <image> With the invention of the microscope, scientists were able to examine the cell up close. http://pixabay.com/en/microscope-whitechemistry-219984/ <image> http://pixabay.com/en/nest-eggs-three-tern- After much research, scientists identified three parts of the cell that provide structure: the cell wall, cell membrane, and cytoplasm. birds-386737/ Question for Clip E Stem: How many structural parts of the cell were identified by scientists with the use of a microscope? Answers for Question E A. One B. Two C. Three D. Four Correct Response C Correct – Go to Clip B Incorrect – Go to Clip F CLIP F Remediation for Clip B – 25 to 35 seconds Visual Audio <image> Most cells can be separated into two groups: plant cells and animal cells. http://pixabay.com/en/pigeons-couple-pairtwosome-birds-50005/ <image> Plant and animal cells share two structural parts, or organelles: the cell membrane and cytoplasm. http://www.morguefile.com/archive/display/ 860528 <image> Animal cells do not have a cell wall. http://www.morguefile.com/archive/display/ 946948 <image> Only plant cells have cell walls, which provide the plant with a strong rigid structure. http://www.morguefile.com/archive/display/ 939674 Question for Clip F Stem: Which of the following organelles do plant cells and animal cells share? Answers for Question F A. Cell Wall B. Cell Membrane C. Chloroplast D. Central Vacuole Correct Response B Correct – Go to Clip C Incorrect – Intervention Alert – then Clip B CLIP G Remediation for Clip C – 25 to 35 seconds Visual Audio <image> Also known as the plasma membrane, both animal and plant cells have cell membranes. http://pixabay.com/en/insects-plant-greenants-106539/ <image> Cell membranes are responsible for sifting or sorting what goes in and out of the cell. http://pixabay.com/en/swim-car-washsorting-plant-apple-196796/ <image> This quality of the cell membrane is known as selective permeability. http://pixabay.com/en/man-packagingworkers-pack-sort-196804/ <image> This selective characteristic protects the cells from harmful chemicals and other foreign objects. http://www.morguefile.com/archive/display/ 57481 Question for Clip G Stem: Which of the following is a synonym for sifting or sorting? Answers for Question G A. Selectively Permissive B. Selectively Permeable C. Solidly Permeable D.
