Also, to prevent be… To reproduce they release seeds into the water synchronously in reaction to light, temperature,or tides to increase the fertilization rate. In some cases, the blades have a distinct midrib. Seaweed can only live in sea water and it needs enough sunlight reaching them so they can carry on the process of photosynthesis. However there are several types of plants that live in water such as lichens, sponges, and red/brown/green algae. This occurs because individuals with these traits are better adapted to the environment and therefore more likely to survive and breed. It is not a quick process! Along the northeast coast of the US, there is a toxic phytoplankton species, Alexandrium fundyense, which produces very toxic blooms. Adaptation to Shallows (subtidal to 30 meters) Less wave Action Environmental Adaptation. Heavy wave action; Small, tough stipes and blades; Strong holdfasts; Hydrodynamic shapes; Low surface to volume ratio; Dessication; Low surface to volume ratio; Trap water. Aquatic algae demonstrates photosensitive and cosmetic adaptation throughout the ocean. They are eukaryotic organisms and lack any vascular tissue (for the transport of water and other compounds such as sugars) or any organised tissue. A weak _____ is an adaptation of a water lily, allowing it to focus on the expansion of its leaf. Natural selection over many generations results in helpful traits becoming more common in a population. The _____ of this plant attracts pollinators, such as bees. Kolkwitz listed 61 diatoms, 42 green algae, 41 pigmented flagellates, 23 blue-green algae, and 5 red algae as organisms of oligosaprobic and /or unpolluted zones and Lackey found 77 species of planktonic algae in the clean water portion of a small stream, 40 of which were absent in the polluted area[15,16]. They create a gelatinous polycarride that helps to retain water. Seaweed does not have roots like terrestrial plants and trees because they do not need to absorb water and nutrition from the soil. The seaweed can have one or more blades, and the blades can have different shapes. Photosynthesis takes place primarily in the blades and it is, therefore, important that the stipe is long enough to place them sufficiently close to the surface of the water … Copepods, small crustaceans and the most abundant animals in the world, are main consumers of toxic algae. Seaweed (or macroalgae) are a diverse group of mostly photosynthetic algae found in marine and freshwater environments. They create a gelatinous polycarride that help to retain water. If algae originated from a single strain, environmental evolutions have forced the adaptation into red, brown, yellow and green colour algae which each blend in with their environmental surroundings. Like plants on earth use carbon dioxide and sunlight to produce oxygen for human beings to survive, seaweed use carbon dioxide in water and sunlight to produce carbohydrates for the marine life to survive. To reproduce they release seeds into the water synchronously in reaction to light, temperature, or tides to increase the fertilization rate. Adaptation is an evolutionary process whereby an organism becomes increasingly well suited to living in a particular habitat. In other words, the predators may adapt and would be able to eat lots of toxic prey without being poisoned. Seaweed. Two experimental feeding trials were conducted during four weeks to evaluate the use of Ulva lactuca in shrimp culture: (1) for wastewater bioremediation, and (2) using different inclusion levels of U. lactuca meal in shrimp feed. As they heavily depend on water, it becomes a limiting factor for their survival. Mar 18, 2014 - Seaweed Seaweed has had to adapt a lot because it lives under water or very close to water.
