Name ____________________ Period____ Date____________ CELL Processes Quiz TRANSPORT: Match the definition on the left with the term on the right. 1. _____ release of wastes or cell products from inside to outside a cell 2. _____ diffusion of water molecules through a selectively permeable membrane 3. _____ continuous movement of particles but no overall change in concentration 4. _____ movement of particles from an area of higher concentration to one of lower concentration a. b. c. d. diffusion dynamic equilibrium exocytosis osmosis In the space at the left, write true if the statement is true. If the statement is false, change the italicized term to make the statement true. Write this answer in the blank provided. _______________ 5. In passive transport, the movement of particles across a membrane requires energy. _______________ 6. Endocytosis is a process by which a cell membrane surrounds and takes in material from the environment. _______________ 7. A membrane that allows only some materials to pass through shows selective permeability. Circle the word or phrase that best completes the statement or answers the question. 8. The structure most responsible for maintaining cell homeostasis is the A. cytoplasm B. cell wall C. mitochondria D. cell membrane 9. A cell membrane is made up of a(n) A. cholesterol layer B. enzyme layer C. phospholipid bilayer D. protein layer 10. Which of the following is not a form of passive transport? A. diffusion B. endocytosis C. osmosis D. facilitated diffusion 12. If a cell is placed in salt water, water leaves the cell by A. osmosis B. diffusion C. active transport D. phagocytosis 13. A cell moves particles from a region of low concentration to a region of higher concentration by A. diffusion B. osmosis C. passive transport D. active transport Use the picture on the left to answer the questions on the right. 14. = oxygen molecule cell a. Which side has the higher concentration of oxygen (inside the cell or outside)? ________ b. Which way will the oxygen go? ________________________ c. Does this require energy? ___________ d. Is this active or passive transport? _______________________ Label the pictures for each solution (isotonic, hypotonic, or hypertonic): Pay close attention to the arrows!!! ________________ MITOSIS: ________________ ________________
