Elodea canadensis

• Elodea is a plant that lives in fresh water environments.

• In many places, elodea has grown so well that it has become a problem in ponds and creeks.

Reproduction

• Elodea reproduces sexually using tiny white flowers that stick out above the water surface.

Asexual Reproduction

• Since roots are less of a need in water, elodea stalks can break off and float to new locations where they continue to grow.

Providing Habitat & Nutrients

• Elodea provides vital habitat and cover for many aquatic fishes, and other creatures

• It is a common aquatic plant sold in pet shops.

• Ducks, Muskrats, and other creatures feed on elodea.

Cell Parts (Organelles)

• Chloroplasts are little green dots inside the cell where photosynthesis happens.

• The nucleus is where the DNA is stored

• The cell wall surrounds the cells and provides structure for the plant.
