Cell Structure & Function SC.912.L.14.3 Jorge's class was examining different types of cells under the microscope. Jorge looked at both eukaryotic and prokaryotic cells. Which of the following would the class see when comparing these cells? A. Only prokaryotes have cell walls. B. Only eukaryotes eukaryoteshave haveaamembrane-bound membrane-bound nucleus. C. Prokaryotic cells do not contain DNA. D. Eukaryotic cells do not undergo cell division. Unlike the porous cells of the kidney, the cells of the top layer of skin are made of a tough, nearly waterproof substance. Which of the following is a characteristic of these eukaryotic cells? A. They have cell walls. B. They do not contain membrane-bound nuclei. C. Their DNA DNA isis organized organizedinto intochromosomes. chromosomes. D. Their genetic information is contained in a single loop. Which of the following structures are found in plant cells but not in animal cells? A. cytoskeleton and Golgi apparatus B. mitochondria and ribosomes C. cell walls walls and and chloroplasts chloroplasts D. vacuoles and endoplasmic reticulum Which of the following best describes the major difference between prokaryotic cells and eukaryotic cells? A. Prokaryotic cells are plants cells and eukaryotic cells are animal cells. B. Eukaryotic Eukaryotic cells cellshave haveaanucleus nucleusand andmembranemembranebound organelles, organelles, and andprokaryotic prokaryoticcells cellsdo donot. not. C. Prokaryotes are multicellular organisms while eukaryotic cells are single-celled organisms. D. Eukaryotic cells contain DNA while prokaryotic cells do not. Which of the following incorrectly pairs a cell structure with its function for both plant and animal cells? A. Nucleus: storage area for the cell's genetic material B. Mitochondria: used to supply energy for the cell C. Vacuole: sac used for storage of waste, water, or materials needed by the cell D. Cell membrane: membrane: site siteof ofprotein proteinsynthesis synthesis Animal cells have all of the following except which structure? A. lysosome B. central vacuole vacuole C. cell membrane D. ribosome Which of the following is true of all single-celled organisms? A. They all have chloroplasts containing chlorophyll. B. They all have membrane-bound organelles. C. They all have nuclei containing DNA. D. They all all have have plasma plasmamembranes. membranes. Which of the following is a common characteristic of almost all plant cells, with only a few exceptions? A. They have lysosomes. B. They have flagella. C. They have have chloroplasts. chloroplasts. D. They have small vacuoles. There are some similarities between prokaryotic and eukaryotic cells. Which of the following structures is found in both prokaryotic and eukaryotic cells? A. lysosome B. mitochondrion C. nucleus D. ribosome ribosome A student is observing a group of cells under a microscope. What observation would help the student conclude that the cells observed are plant cells? a. The presence of nuclei can be clearly detected within each cell b. cellsappear appearwell-defined, well-defined,indicating indicating b. The The cells thethe presence presence cell walls. of cellof walls c. The presence of mitochondria can be clearly detected within each cell. d. The cytoplasm in which the cell organelles are embedded can be clearly seen.
