Dense growth of elodea can interfere with some uses of the pond, such as boating and fishing. Excessive growth can also reduce dissolved oxygen levels during the summer causing fish kills. Prevention. Overabundant growth of elodea is a symptom of excessive nutrients (phosphorus and nitrogen) in the pond water.
Elodea canadensis (American waterweed or Canadian waterweed or pondweed) is a perennial aquatic plant, or submergent macrophyte, native to most of North America. It has been introduced widely to regions outside its native range and was first recorded from the British Isles in about 1836.
What Is the Structure of an Elodea Cell? An Elodea cell consists of a semi-permeable cell wall, which contains a membrane, enveloping the cytoplasm, in which a nucleus, vacuole, chloroplasts and mitochondria are located. Some of these structures can be clearly seen under a compound microscope.

Pass out the Elodea images, rulers, and student pages, then lead students in the explorations on the student pages.; Note that student answers will vary depending on the cell they choose and their measurement technique. For the bonus question, the answer should be similar to this example: If the area of a cell is 0.00125 mm 2, then the approximate number of cells in a leaf that is 55 mm 2 and ...
Elodea can be removed by raking or seining it from the pond, but will re-establish from any remaining fragments and roots. Fertilization to produce a phytoplankton or algal “bloom” prevents the establishment of most bottom rooted aquatic weeds and produces a strong food chain to the pond fish.
