Biology cells Questions and Answers with Certified Solutions

Biology cells Questions and Answers with Certified Solutions What is shown in the image? eukaryote The endosymbiotic theory helps to explain the origin of which structures? mitochondria Which statement is most likely to apply to a cell that has DNA within its cytoplasm? It performs all functions for the organism. Which statement is least likely to support the endosymbiotic theory? Mitochondria and chloroplasts are much larger than prokaryotic cells. A scientist is studying a cell and can clearly see that it has ribosomes and mitochondria. Which statement best describes how the cell could be classified? The cell is eukaryotic because it contains mitochondria. Which cell structure serves the stated function in both eukaryotic and prokaryotic cells? cytoplasm: protects cell structures A chemical has been found to harm the same components in both prokaryotic and eukaryotic cells. Which components are those? DNA, cell membrane, cytoplasm, and ribosomes A student wonders whether removing the nucleus from a cell would result in a new prokaryotic cell. Why would this procedure fail to produce a prokaryotic cell? The cell would lack genetic information. Based on the endosymbiotic theory, what cell would result from the endosymbiosis of a cell with a cyanobacterium? a eukaryotic cell that can make its own food The discovery of mitochondrial DNA (mtDNA) had no effect on which area of scientific investigation? study of cork bark Two cells in the same organism differ only in the number of chloroplasts they contain. The first cell has multiple chloroplasts, and the second cell has very few. What would most likely characterize these cells? The second cell would not be able to produce as much food because it could not capture sunlight. The table lists some organelles and functions. Only one pair is correctly matched. Which organelle in the table is correctly matched with its function? nucleus The endosymbiotic theory states that chloroplasts and mitochondria evolved as a result of a prokaryotic cell engulfing a bacterial cell. The table lists some organelles and functions. Only one pair is correctly matched. Which organelle in the table is correctly matched with its function? ribosome Which organelle is not found in plant cells? centrioles Which two microscopes generate three-dimensional images? scanning electron microscope and scanning tunneling microscope A new multicellular organism has been discovered, and scientists want to study the organism's cell structures, including organelles. Which microscope should they use? transmission electron microscope Which is a function of the cell membrane? controls what enters and leaves the cell What is shown in the image? prokaryote According to the endosymbiotic theory, which cellular process was involved in the evolution of mitochondria and chloroplasts? phagocytosis What is the maximum magnification of a compound light microscope? 2,500x Which microscope uses a probe to map atoms on the surface of a specimen? scanning tunneling microscope
