Aquatic Plants
Aquatic plants grow wholly or partially in water. Some, like the lotus, are rooted in mud, while others, like the water hyacinth, float on the surface of water. Water plants enhance ponds and water features in landscaping.

Why do the roots of some aquatic plants become reduced or at times absent?
Root pressure is osmotic pressure within the cells of a root system that causes sap to rise through a plant stem to the leaves.
Root pressure occurs in the xylem of some vascular plants when the soil moisture level is high either at night or whentranspiration is low during the day. When transpiration is high, xylem sap is usually under tension, rather than under pressure, due to transpirational pull. At night in some plants, root pressure causes guttation or exudation of drops of xylem sap from the tips or edges of leaves. Root pressure is studied by removing the shoot of a plant near the soil level. Xylem sap will exude from the cut stemfor hours or days due to root pressure. If a pressure gauge is attached to the cut stem, the root pressure can be measured.
Root pressure is caused by active distribution of mineral nutrient ions into the root xylem. Without transpiration to carry the ions up the stem, they accumulate in the root xylem and lower the water potential. Water then diffuses from the soil into the root xylem due toosmosis. Root pressure is caused by this accumulation of water in the xylem pushing on the rigid cells. Root pressure provides a force, which pushes water up the stem, but it is not enough to account for the movement of water to leaves at the top of the tallesttrees. The maximum root pressure measured in some plants can raise water only to about 7 meters, and the tallest trees are over 100 meters tall.
What is the function of the layers of wax found on the leaves of floating aquatic plants?
The wax on the leaves prevents decomposition of the leaf.
What does predominantly aquatic means?
"Predominantly aquatic" refers to organisms or environments that are primarily associated with water. This term is often used to describe species that live most of their life in aquatic habitats, such as fish, amphibians, and certain plants. It implies that water is the main medium for survival and reproduction, although these organisms may occasionally interact with terrestrial environments.
What does a pickerel weed look like?
A tall plant with blue flowers and glossy foliage for pool margins is the look of pickerel weed. The Pontederia genus member in question matures to a height of 2 to 2.5 feet (60 to 75 centimeters) and a width of 1.5 feet (45 centimeters) within three to four years. The aquatic plant in question needs full sun and water depths of 2 to 8 inches (5 to 20 centimeters) to produce repeat blooms, facilitated by stem cuts as flowers fade, throughout the summer.
Are actinic bulbs good for non-aquatic plant growth?
yes. Actinic light give off a large amount of blue light which is needed for vegetative growth.
What are protective structure?
Their Protective Structure is their Sharp Teeth:L Yeah men :))Not sure :)
What gas does pond weed release?
Oxygen is the gas that pond weed releases. The Potamogeton genus member in question removes atmospheric carbon dioxide for photosyntheseis. The aquatic plant in question tackles air and water pollution by decreasing carbon dioxide levels and increasing oxygen levels through the closing and opening of foliar pores.
Can pondweed survive in fresh-moving water?
Yes, pondweed can survive in fresh-moving water. In the specific case of curly pondweed (Potamogeton crispus), the type of aquatic plant in questions has the survivalist's advantage of adapting to deep or shallow, flowing or still waters.
Why aquatic plants and animal survive in the cold region?
Most aquatic animals living in cold climates can survive quite nicely thanks to their adaptations. Some animals have hair and others like whales have a tremendous amount of blubber that helps to insulate them from cold temperatures.
What two outcomes can be expected as a result of an overabundance of aquatic plant life?
The plants will die and decay, causing a decrease in dissolved oxygen; plants will block sunlight to deeper water.
Does photosynthesis occurs in aquatic plants?
yes it does
Aquatic plants are normal plants. They should undergo photosynthesis to get food and energy
According to me aquatic wildlife means reptiles,amphibians,mammals and birds that inhabits the waterbody and its immediate vicinity,with particular focus on species that have substantial impact on fish population
What are the Himalayan balsam's adaptations?
Himalayan balsam (Impatiens glandulifera) has spread extensively along riverbanks, damp ditches and waste land. It is classed as a troublesome weed as it grows abundantly and smothers other native plants. The ripe seeds will explode and scatter when brushed against by animal or a person walking past. The Himalayan balsam is a relative of the busy Lizzie, though a lot taller.
How does a cuticle in an aquatic plant differ from a desert plant?
In aquatic plants, the cuticle is often much thinner or even absent because they are submerged in water, allowing for easy gas exchange and nutrient absorption. In contrast, desert plants have a thick, waxy cuticle that helps minimize water loss and protect against harsh environmental conditions. This adaptation is crucial for survival in arid environments, where conserving moisture is essential for the plant's survival.
How do aquatic plants float on water?
Some plants, like water hyacinth, float in water. They have special types of leaves that help them to stay afloat.
