Elodea Cells:  Plant Cell

Purpose:  The purpose of this lab investigation is to prepare a wet mount of an elodea leaf in order to examine a plant cell.

Materials and Methods:  This experiment requires clean glass slides, cover slips, elodea, forceps, droppers, microscopes and lens paper.

Prepare a wet mount using one leaf from the elodea vine.  Use forceps to remove a leaf from the elodea leaf and place it onto the slide.  Add a drop of water and then lower a cover slip over the leaf and water.  (Lower the cover slip by first placing one edge against the drop of water at about 45 degrees.)  

Experiment:  Find the cells on low power, but make your observations using the high power objective.  Be sure to adjust the lighting with the iris diaphragm.

Locate the following:  cell wall, central vacuole, chloroplasts, and cytoplasm.  Often the cytoplasm and chloroplasts will be moving around within the cell.  This is a process called cytoplasmic streaming.

Make a sketch of a typical cell below, and label it.   Assume the box is the cell wall.

                  

Conclusion:  What features did you observe that are unique to the plant cell?
