Name:______________________________________________ REGENTS REVIEW QUESTIONS FOR CELL ORGANELLES & THEIR FUNCTIONS 1. The diagram below represents a cell found in some complex organisms. The enlarged section represents an organelle, labeled X, found in this cell. Describe the function of organelle X and explain how it is important to the survival of the cell. In your answer, be sure to: identify organelle X [1] state the process that this organelle performs [1] __________________________________________________________________________________________ mitochondria Cellular respiration (it makes energy for the cell) 2. Which structures carry out life functions within cells? 3 (1) tissues (2) organ systems (3) organelles (4) organs 3. An organelle that releases energy for metabolic activity in a nerve cell is the (1) chloroplast (2) ribosome (3) mitochondrion (4) vacuole 3 4. The table below provides some information concerning organelles and organs. Based on this information, which statement accurately compares organelles to organs? 3 (1) Functions are carried out more efficiently by organs than by organelles. (2) Organs maintain homeostasis while organelles do not. (3) Organelles carry out functions similar to those of organs. (4) Organelles function in multicellular organisms while organs function in single-celled organisms. 5. Write the structures listed below in order from least complex to most complex. [1] organ cell organism organelle tissue organelle cell tissue organ organism Base your answers to questions 6 through 8 on the diagrams below and on your knowledge of biology. The diagrams represent two different cells and some of their parts. The diagrams are not drawn to scale. 6. Identify an organelle in cell A that is the site of autotrophic nutrition. [1] chloroplast 7. Identify the organelle labeled X in cell B. [1] ribosome 8. Which statement best describes these cells? 3 (1) Cell B lacks vacuoles while cell A has them. (2) DNA would not be found in either cell A or cell B. (3) Both cell A and cell B use energy released from ATP. (4) Both cell A and cell B produce antibiotics. 9. Which organelle is correctly paired with its specific function? (1) cell membrane—storage of hereditary information (2) chloroplast—transport of materials (3) ribosome—synthesis of proteins (4) vacuole—production of ATP 3
