The stems have tough internal fibres and a hollow Fragrant White Water Lily The fragrant white water lily (Nymphaea odorata) is a perennial river plant that has heart-shaped leaves that grow up to 12 inches in diameter. They show the necessity for adaptation not only in freshwater stream systems, but also on tropical islands that are often affected by harsh geographical and meteorological conditions. Water lilies and cattails have different adaptations for life in the water. Water provides all the necessary support, They grow above water but drape down so that their tips are sometimes submerged. Plants in Plain May have several branches. 3) At very low temperatures in winter, the soil water freezes and hence becomes unavailable to the roots of trees and plants. floating or emergent leaves on the same plant. Stomata (breathing Their height means that they are unlikely to ever be completely likely to be damaged. those which are rooted with floating leaves (e.g. For example, cattails have narrow, strap-like leaves that reduce their resistance to the moving water (see Figure below). Their height means that they are unlikely to ever be completely submerged during flooding. Adaptations are genetic and evolutionary traits that are unique to a species or group of species and allow them to live in a specific environment. In the case of freshwater environments, some animals and plants have adapted to live where the environment is tumultuous or in some way requires traits that they do not typically need. Their shape allows them to be moved freely by running water, but also keeps them from tearing during this continuous action. The most common adaptation is the presence of lightweight internal packing cells, aerenchyma, but floating leaves and finely dissected leaves are also common. These fish also have pelvic sucking disks which allow them to attach to rocks and other hard surfaces in order to withstand strong tidal movements. Heterophylly, where leaves of different shapes Plant Adaptations in Water Some plants have air spaces in their stems to help hold the plant up in the water. The speed of water also varies and is subject to chaotic turbulence. When these fish are adults, they are adapted to swimming against the current in order to get back upstream and into the freshwater streams. Aerenchyma are important adaptations for many species of freshwater plants. This is a spongy tissue composed of holes made by cells either breaking apart or disintegrating. These trees, called mangroves, have wide-spreading stilt roots that support the trees in the tidal mud and trap nutritious organic matter. surface of the leaves which are the only surface to be well lit. stems of aquatic plants, providing an internal atmosphere. required by land plants to limit water loss. They are therefore less likely to be damaged. Every plant has evolved unique adaptations, or physical features that help it survive in this dense jungle.

Adaptations are special features that allow a plant or animal to live in a particular habitat, but make it difficult for them to live somewhere different. and collect the lion's share of the light available. This is because the normal water transport system is poorly developed. University of California Los Angeles: Aquatic Plants. an enormous quantity of structural material in order to rise above all the other plants When these fish are adults, they are adapted to swimming against the current in order to get back upstream and into the freshwater streams. Estuaries house plant life with the unique adaptation of being able to survive in fresh and salty environments. On tropical deltas and along ocean edges and river estuaries, trees have adapted to living in wet, marshy conditions. generally tough because they have to withstand the weather and water movement. As a Plants who live in still waters have different adaptations. For example, fish that are adapted to fast water can have a streamlined shape like darters to minimize the force of the current, or fins like a sculpin that anchor them to rocks. pores), through which gas exchange takes place in the leaf, are also found only on the Seals are semiaquatic; they spend the majority of their time in the water, but need to return to land for important activities such as mating, breeding and molting. Indeed, this would be a distinct disadvantage as it would limit flexibility in the event A supported by water all around them and so have no need of mechanical strengthening. River dolphins and manatees are both fully aquatic and therefore are completely tethered to a life in the water. Adaptations of Plants in the Taiga Biome. placed in water.
