The cell will both gain and lose equal amounts of water; thus, it will remain the same size. The cell will undergo no exchange of water with its surroundings. A. will be no change in the cell B. the cell will shrink C. the cell will swell D. the cell will divide While cleaning a saltwater aquarium, students placed the aquarium plants in a container of distilled water. What effect will this have on the plants? The cells will swell. The plant cells will separate. The plant cells will remain the same. The plant cells will shrink 4. An plant is placed into distilled water. What will happen to the cell? A. water will flow out of the cell and cause it to wilt B. water will flow into the cell and it will burst C. water will flow into the cell, but it will not burst only become swollen D. water will flow in and out of the cell, but the size of the cell will not change Part 7: Answer the following transport questions. Use the manipulatives in class if necessary. Describe the cell membrane. Draw a picture to help support your description. Include the following: lipid, protein, bilayer. Explain the key difference between passive and active transport. If someone is sitting across the room smoking, you may still breathe in some of the smoke. The movement of smoke across the room is an example of what type of transport? Osmosis C. facilitated diffusion Diffusion D. active transport EXPLAIN WHY: Using terms from this unit, describe what would happen to a slug if you poured salt on it. Draw arrows too! [HINT: slugs are very watery inside!] The membrane only lets molecule D cross. Over time, what will happen to the molecules in the figure to the right? While cleaning a saltwater tank, students placed a salt water cell in a bowl filled with regular tap water. What effect will this have on the cell? The cells of the protozoan will disintegrate. The cells will swell. The cells will shrink and shrivel. The cells will remain the same. EXPLAIN: Placing wilted lettuce in cold water will make it crisp again. Which statement best describes what happens to restore the lettuce to its original condition? Water left the lettuce cells by diffusion. Water entered the cells of the lettuce by osmosis. Osmosis caused to enter the lettuce cells. Salts in the leaf caused water to leave the cells.
the cut-outs at your table, set up both bioenergetics reactions. Then draw the answers in the boxes so that they are permanently in your notes. The pluses (+) and arrows () can be placed in the small boxes.
