Biology 11: The Cell, Cell Theory & Characteristics of Living Things TEST REVIEW Name:_____________________________ Section I: Parts of the cell a) Please label the following diagram in the spaces provided. b) Label the cells above as plant or animal and give 2 reasons to justify your choice. c) Are the cells above prokaryotic or eukaryotic? How do you know? Section II: Cell organelle functions Please match the letter of the correct function with the appropriate cell part in the spaces 1. _____ golgi body 2. _____ nucleus 3. _____ ribosome a) site of cellular respiration: makes usable energy b) “control center” of cell, contains DNA c) modifies, stores and transports proteins d) site of photosynthesis e) synthesizes (builds) proteins f) breaks down cell waste with enzymes 4. _____ mitochondria 5. _____ chloroplast 6. _____ lysosome Section III: Short Answer 1. Why was the microscope such an important tool for the development of the cell theory? 2. An elementary student thinks that a lawn mower is alive. Convince her that it is NOT. Be sure to discuss the characteristics of life in your answer. 3. What are stem cells and what are some examples of how they can be used to treat diseases/ disorders? Section IV: True or False Indicate if statement is true or false. FIX any that are false ____ 1. The DNA cannot leave the nucleus of the cell and thus sends messages to the cytoplasm. ____ 2. The smooth endoplasmic reticulum packages proteins. ____ 3. In plant cells, cellular respiration occurs in chloroplasts. ____ 4. Eukaryotic cells contain a true nucleus. ____ 5. Ribosomes are located on the Golgi body. Section V – Multiple Choice: Place letter of most correct answer in spaces provided. _____1. The early study of cells by Biologists Schleiden and Schwann contributed to the formation of cell theory. What is the most probable reason that these early scientists never viewed cell organelles such as ribosomes? a. ribosomes cannot be viewed unless the cell is stained with iodine b. ribosomes are much too small to be seen with early microscopes c. primitive cells did not need to synthesize proteins d. all cells do not have ribosomes ____2. Biology is: a. The study of cells b. The study of life c. The study of animals d. The study of microscopes ____3. Which statement is not true of the cell theory? a. cells come from preexisting cells. b. cells are dependent on other cells for life. c. cells are the structural and functional units of life. d. all living things are made of one or more cells. ____4.
