Substances produced in a cell and exported outside of the cell would pass through the a. endoplasmic reticulum and cell membrane. b. mitochondria and cell membrane. c. nucleus and endoplasmic reticulum. d. ribosomes endoplasmic reticulum. 6. Cells that have a high energy requirement generally have many a. nuclei b. flagella c. mitochondria d. microfilaments 7. Organelles that are surrounded by two membranes and contain DNA are the a. nucleus, the endoplasmic reticulum, and lysosomes. b. nucleus, the endoplasmic reticulum, and chloroplast. c. nucleus, chloroplast, and mitochondria. d. endoplasmic reticulum, mitochondria, and the Golgi apparatus. 8. Plasma membranes a. are part of only a small number of cells. b. contain genes. c. are made of DNA. d. are thin coverings that surround cells. 1 9.

A structure within a cell that performs a specific function is called a(n) a. organelle. c. tissue. b. organ tissue. d. biocenter. 11. A particularly active cell might contain large numbers of a. chromosomes. c. mitochondria. b. vacuoles. d. walls. 12. One important organelle that helps maintain homeostasis by moving supplies from one part of the cell to the other is the a. endoplasmic reticulum. c. nucleus. b. mitochondrion. d. cytoplasm. 13. In which of the following organelles is a cell’s ATP produced? a. mitochondrion c. Golgi apparatus b. endoplasmic reticulum d. lysosome 14. Proteins are made on the a. mitochondria. b. ribosomes. c. nucleus. d. plasma membrane. 2 15. Refer to the illustration above. Which structure immediately identifies this cell as a eukaryote? a. structure 1 c. structure 3 b. structure 2 d. structure 4 16. Refer to the illustration above. The cell uses structure 3 a. to transport material from one part of the cell to another. b. to package proteins so they can be stored by the cell. c. as a receptor. d. to transfer energy from organic molecules to ATP. 17. Refer to the illustration above. Structure 1 is a. the endoplasmic reticulum. b. a Golgi apparatus. c. a mitochondrion. d. the nucleus. 18. Refer to the illustration above. This cell’s chromosomes are found in a. structure 1. c. structure 3. b. structure 2. d. structure 5. 19. Refer to the illustration above. The cell shown is probably an animal cell because a. it has mitochondria. b. it does not have a cell wall. c. it has a plasma membrane. d. it does not have a nucleus. 20. All of the following are found in both plant and animal cells, except a. a cell wall. c. mitochondria. b. a plasma membrane. d. the endoplasmic reticulum. 3 21. The organelles associated with photosynthesis are the a. mitochondria. c. Golgi apparatus. b. chloroplasts. d. vacuoles. Short Answer Answer the questions in the space provided. 22. Describe the structure of the cell membrane. 23. Which organelles are surrounded by two membranes? 24. What roles do membrane proteins play in making the cell membrane selectively permeable? 25. What cellular functions are ribosome’s involved in? 26. What are plant cell walls made of? 27. What is the function of cells walls? Critical Thinking When lipid is added to a solution of a detergent in water, the detergent breaks up large globules of the lipid into much smaller globules. What effect do you think a detergent would have on the integrity of cells? Explain your answer. 4 Structures and Functions Label each part of the figure in the spaces provided. This diagram represents a typical plant cell. 5 Structure and Function Complete the table by writing the name of the cell part beside its structure/function. A cell part may be used more than once. Structure/Function Cell Part The site of protein & RNA synthesis A folded membrane that forms an intracellular highway in the cytoplasm The clear fluid inside the cell Organelle that manages cell functions in eukaryotic cell Contains chlorophyll, a green pigment that traps energy from sunlight and gives plants their green color Small bumps located on the endoplasmic reticulum Firm, protective structure that gives the cell its shape in plants Produce a usable form of energy for the cell Contains inner membranes arranged in stacks of membranous sacs called thykaliods 6
