so it will protect them from predators
Water milfoil is a flowering plant despite living in water. Its flowers need to be pollinated in order for it to make seeds. It is wind pollinated so the flowers need to be above the water.
Emergent
The flowers of pondweed grow above the water to facilitate pollination and reproduction. By extending their flowers above the surface, they can attract pollinators like insects and access air for pollen dispersal, which is essential for fertilization. Additionally, being above the water helps prevent the flowers from being submerged, ensuring they can effectively produce seeds and propagate the species.
Accessibility to pollinating insects is a reason why pond weed flowers grow above the water. Aquatic plants whose male variety's pollen grains are water-pollinated by a female variety's floral stigmas contrastingly will not need the above-surface flowerings.
Having flowers above the surface increases the number of pollinators who will reach the flower, such as bees and beetles. it also enables them to receive the pollen of flowers of the same species from a different body of water
Water lilies have round, flat leaves that float on the water's surface, while lotus plants have leaves that are more upright and held above the water. Additionally, water lilies bloom with flowers that float on the water, while lotus flowers are held above the water on tall stalks.
No, Cabomba is a partially-submerged plant. It is rooted in soil at the bottom of the pond with its leaves, flowers, fruits on or above the surface of the water.
Approximately 10 of an iceberg is typically visible above the water's surface.
above the water
The upper surface of water is called the water's surface or water level. It is the boundary where the water meets the air above it.
Freshwater plants grow in ponds, lakes, rivers, and streams. Most have roots which anchor them in the mud at the bottom. Their stems grow through the water and their leaves and flowers open above the water's surface.
Water milfoil (Myriophyllum) form flowers on the surface of the water as part of their reproductive process. These emergent flowers help facilitate pollination by attracting insects such as bees and flies, allowing for efficient fertilization of the plant's seeds. The flowers also enable the dispersal of seeds, ensuring the continuation of the milfoil species.
