What is the adaptation for elodea canadensis to float?

Elodea canadensis, commonly known as Canadian waterweed, has adaptations that allow it to float and thrive in aquatic environments. Its long, slender stems are buoyant, supported by air-filled spaces within the tissues, which help the plant remain suspended in the water column. Additionally, the leaves are finely dissected, reducing resistance to water flow and allowing the plant to capture sunlight efficiently for photosynthesis. These features enable Elodea to effectively compete for light and nutrients in its habitat.
