Acc Bio/Biology Lab Table _____ Cell Manipulative Read about the structure and/or function of these cell parts/organelles, determine what they are, then place them in the cell where their number is. Using these manipulative pieces, build first an animal cell, then using a lot of the same parts, build a plant cell. 1. I am the gel-like substance enclosed within the cell membrane, in which the organelles are suspended. What am I? 2. I am the Control Center of the cell. I contain genetic material (DNA and protein as chromatin, chromatids, chromosomes). What am I? 3. I carry out a process called Cellular Respiration. When you eat food (glucose is my favorite!) and breath oxygen, I can make 36 molecules of ATP. You use this energy (ATP) to perform cellular processes. I am your Power House, what am I? 4. In animal cells I am a modified vesicle that has digestive enzymes. Some call me the “package of destruction.” What am I? In a plant cell I get very large, hold water and dissolved nutrients and salts. When I’m full plants look healthy and strong, when I lose water, plants look wilted and unhealthy. What am I? 5. I am an internal delivery system, moving materials throughout the cell. If ribosomes are attached to me I am rough and aid in the production of protein. Further from the nucleus, where I don’t have ribosomes, I make lipids and am responsible for the break down of drugs and alcohol. I am made up of folds of membranes. What am I? 6. I am sometimes compared to UPS, Fed Ex, or the Postal Service because I am the packaging center of the cell. I receive vesicles that have pinched off of the Endoplasmic Reticulum and fuse with my membranes. I am responsible for the final modifications, packaging and release of proteins, which are packaged in a vesicle for transport throughout the cell or out of the cell all together. What am I? 7. In an animal cell I become visible when the cell is preparing to divide – for purposes of growth, cell replacement, or repair. I am responsible for organizing the chromosomes to ensure that one copy of each chromosome gets into my new cells. What am I? In a plant cell I allow the plant to make its own food. The process is called Photosynthesis. My chlorophyll can absorb light energy which can Break down water and use the Hydrogens and Oxygens, along with Carbons (from Carbon Dioxide, CO2) to make sugar: CH2O. Once I have sugar I have the backbone to all four macromolecules necessary for life. If I get more water, and nutrients like Nitrogen and Phosphate from the soil or a Fertilizer, I can make carbohydrates, lipids, proteins, and nucleic acids for the plant. What am I? 8. I am made of a bilipid layer, I have proteins embedded in me for support, structure, and to transport molecules into and out of my cell. The transport proteins are either call channels (if the transport requires no energy) or pumps (if it takes energy, ATP to move molecules across me). I also have chains of carbohydrates attached to some of the structural proteins. These carbohydrates help in cell recognition. This way your Immune system recognizes me as “self” and it won’t attack my cell. What am I? 9. I am unique to plant cells and bacteria. I am a rigid outer protection that allows for strength, stability, and protection. I am made of cellulose, a complex carbohydrate not found in animal cells. What am I? * If you are doing this at home, please cut out the cell parts provided. * Then make a plant cell an animal cell using the parts provided.
