Name __________________________________________ Period ___ The Big Cells Test Review Directions: Write the name of the organelle that performs each cell function in the space provided. cell membrane nucleus ribososmes endoplasmic reticulum mitochondria golgi complex vaculoes lysosomes 1. _______________ This organelle controls what enters and leaves the cell. It is known as the cell’s “gatekeeper.” 2. _______________ This organelle “burns” food molecules. It turns food energy into cellular energy. 3. _______________ These structures are like little protein factories. 4. _______________ This organelle is the packaging center for the cell. It processes proteins and other materials. 5. _______________ This organelle is the recycling center for the cell. It also destroys worn out cell parts and destroys cell invaders. 6. _______________ This structure is the control center for the cell. It stores the cell’s DNA. 7. _______________ This structure stores water and other liquids for the cell. They are very big in plant cells. 8. _______________ This organelle is the delivery system for the cell. Many ribosomes do their work here. (It is a network of membranes located outside of the nucleus). Directions: Answer the following questions. These will resemble the multiple choice questions on your test. 9. If an organism is made up of only one cell it is called ____________________. 10. Which organelle uses sunlight to make sugar (photosynthesis). ____________________ 11. What is the basic unit of all living things? ____________________ 12. What is the name of the molecule that is located in the nucleus of the cell? It contains all of the directions for the cell’s structures and functions? ____________________ 13. When you focus a microscope, never use the coarse adjustment lens with __________ power. 14. Anton von Leeuwenhoek is famous for… _________________________________________________________ _________________________________________________________ 15. What is the function of a cell wall? _________________________________________________________ _________________________________________________________ 16. Which term refers to the diffusion of water molecules through a selectively permeable membrane? _______________________________ 17. The invention of the microscope made it possible for people to discover ____________________ ___ 18. Which of the following statements is part of the cell theory? a. Only plants are composed of cells b. All cells are produced from other cells c. Cells can be produced from nonliving matter 19. What is the function of the cell membrane? _________________________________________________________ _________________________________________________________ ___ 20. Which of the following best describes the function of mitochondria? a. They convert energy from food molecules into energy the cell can use b. They store energy from food molecules c. They store energy from sunlight ___ 21. Cells in multicellular organisms a. b. c. d. All look the same All have the same structure Are often quite different from one another Are the same size in every part of the organism 22. Which term do we use to refer to the movement of water molecules from an area of high concentration to an area of lower concentration? ____________________ 23. How is the cell wall different from the cell membrane? _________________________________________________________ _________________________________________________________ 24. Which organelle stores food and other materials for the cell? ____________________ 25. Which organelle releases chemicals that break down large food particles for the cell and are comparable to a recycling center? ____________________ 26. What is located within the nucleus of the cell? _________________________________________________________ _________________________________________________________ 27. What is the cell membrane composed of? a. b. c. d. Mostly vitamins and minerals Lipids only Mostly lipids and proteins Carbohydrates only 28. A microscope allowed Robert Hook to see “tiny rectangular rooms” he called ____________________ 29. Small grain-line bodies called ____________________produce proteins in cells. 30. A ____________________is group of similar cells that work together to perform a specific function. 31. The diffusion of ____________________molecules through a selectively permeable membrane is called osmosis. Directions: Rank the following in order from smallest to largest. Smallest = 1 Largest = 5 32. __Organ system __Tissue __Cell __Organism __Organ In a paragraph, describe how plant cells and animal cells are different. Be sure to include a topic sentence, 3 or more supporting ideas, and a concluding sentence. _________________________________________________ _________________________________________________ _________________________________________________ _________________________________________________ _________________________________________________ _________________________________________________ _________________________________________________ _________________________________________________ _________________________________________________ _________________________________________________ _________________________________________________ _________________________________________________ _________________________________________________ _________________________________________________ _________________________________________________
