Eukaryotic vs Prokaryotic Cells Questions & Answers 1. Prokaryotic cells - ANSWER-Contain plasma membrane, cytoplasm, DNA, and ribosome. Make up single-celled organisms and cells arise from binary fission. Do not have membrane-bound organelles. 2. Eukaryotic cells - ANSWER-Larger than prokaryotic cells. Make up complex organisms. Cells arise by mitosis or meiosis. Have membrane-bound organelles. 3. Plasma membrane - ANSWER-Cell surface made of a phospholipid bilayer. Controls passage of substances across exchange surfaces. 4. Organelles - ANSWER-Found in both prokaryotic and eukaryotic cells. Perform specific functions within the cell. 5. Phospholipid - ANSWER-Lipid molecule with glycerol, 2 fatty acid chains, and a phosphatecontaining group. Found in the plasma membrane. 6. Chloroplast - ANSWER-Found in plant cells and algal cells. Site of photosynthesis. 7. Cell wall - ANSWER-Found in prokaryotic cells. Acts as protection, helps maintain shape, and prevents dehydration. Most prokaryotes have a peptidoglycan cell wall. 8. Gram-positive organisms - ANSWER-Have a thick peptidoglycan layer. Stained purple in the gram-staining technique. 9. Gram-negative organisms - ANSWER-Have a thin cell wall and an outer envelope containing lipopolysaccharides and lipoproteins. Stained pink or red in the gram-staining technique. CONTINUES...
