B. TYPICAL PLANT LEAF CELL (Western Pond Weed): Pond weed is a great plant for studying plant cells, because the leaves are only two cells thick and it is easy to make mounts and view the cells under the microscope. Use the "close the book" method to make a wet slide of one pond weed leaf. The instructor will demonstrate the procedure. Place the slide on a compound scope and use the "stair- step" procedure to focus on a few cells of the leaf at high power. You should definitely be able to see cell walls and chloroplasts. Rarely, you may see a nucleus. In some of the cells, you may notice that the chloroplasts are moving. They seem to cycle around the center of the cell. This is called cyclosis, and is caused by the cytoplasm streaming around the vacuole carrying some organelles with it. Draw and label ONE cell on the provided drawing area of the next page and label using the labels below: CELL WALL, CHLOROPLASTS, VACUOLE, NUCLEUS (if visible) CPID 810186 10
