Dory is a sunny blue - green algae fish, and she suffers from short-term memory loss. Then one day, she realized that she had forgotten a big thing - her family. Dory lived with the clown fish, Marlin and Nemo, but she believed that someone was looking for her. To find their parents Charlie and Jenny, Dory rampaged through an aquarium built by humans. With the help of Nemo and Marlin, she came to the coast of California from the Great Barrier Reef in Australia, where she met many new friends, including
classification of Gracilaria manilanesis: Empire: Eukaryota Kingdom: Plantae Phylum: Rhodophyta Class: Florideophyceae Order: Gracilariales Family: Gracilariaceae Genus: Glacilaria Species: Glacilaria manilaensis Sources: Yamamoto and Trono, 1994. Red algae such as Gracilaria seaweed is one of the abundant seaweed in Malaysia and is widely cultured from which the agar or carrageenan are extracted for food industry application and used as the tissue culture media.

The Benefits of Algae How often also does a human use or eat algae in his daily life? When most people think of algae, they probably think of something that is slimy, gross, and dirty. Algae may irritate people because it grows in unwanted places like swimming pools and boats. Algae can be toxic and it is slimy, but algae benefits people in all aspects of life. Humans obtain algin from algae to help make ice cream, pudding, face cream, and shoe polish. Algae is present in hamburgers
occurring in the ocean that had never been seen before. Scientists have been recently finding a new type of algae in the ocean that does not have very great effects on the environment. Many say that this alga is probably a type of algae that is similar to the ones that grew millions of years ago; this alga is toxic though. It releases terrible pungent odors that can affect health. This algae was first discovered in Australia by fisherman and is now ruining Australian fishing industries by taking over
In the following study, rock pools from the upper and lower shore of Bracelet Bay, were examined and the organisms within noted. The contents of the two pools were compared. The abiotic variations of the pools were recorded and examined in an attempt to understand why the contents of the pools differed. A greater abundance and variety of organisms was present in the lower shore rock pool, this was due to the lower rock pool being a more benign environment than that of the upper shore. This was
which causes a dense growth of plant life. Eutrophication arises from the oversupply of nutrients, which induces explosive growth of plants and algae which, when such organisms die, they consume the oxygen in the body of water, thereby creating the state of hypoxia (deficiency in the amount of oxygen reaching the tissues) Mechanism of Eutrophication When algae die, they decompose and the nutrients contained in that organic matter are converted into inorganic form by microorganisms. This decomposition
species composition and dominance dissolved oxygen depletion and problems in water treatments. Eutrophication is currently happening to many of the Canadian Lakes including Lake Winnipeg. Since 1969, it has been observed that Cyanobacteria (blue-green algae) has been the reason for the 90% hike in the algal blooms.Cyanobacteria causes a smelly odour and releases toxins that are detrimental to humans and some other organisms. When the lake is enriched with phosphorus, cyanobacteria thrive due to nitrogen-fixing
commonly labeled as Harmful Algal Blooms (HABs), is a natural phenomenon that is caused by an explosion of algae in coastal waters. The algae are single celled protists; plant-like organisms. Because the algae reproduce expeditiously, they manage to alter the color of coastal oceans. However, the name "Red Tide" is a misnomer; many times, the ocean can be multiple colors, ranging from green to blue to yellow. Overall, Red Tide has many negative effects on the environment as well as the health of
certain red algae, and mollusks. Coral reefs are tropical, forming only where surface waters are never cooler than 20° C (68° F). The only difference between a barrier reef and a coral reef is that a barrier reef occurs farther offshore, with a channel or lagoon between it and the shore. The outer layer of a reef consists of living animals, or polyps, of coral. Single-celled algae called zooxanthellae live within the coral polyps, and a skeleton containing filamentous green algae surrounds them
but the fishing industry. The release of nutrients into fresh water lakes, rivers and reservoirs leads to excessive growth of three different plant species: a) Open water algae (phytoplankton) b) Attached algae (periphyton) c) Higher plants (macrophytes) Above all, these organisms encourage the growth of algae, which absorb dissolved oxygen in the water essential for the survival of fish populations. Occasionally, the decomposition of newly-submerged biomass and sediment further reduce
Phosphates are present in many natural waters, such as lakes and streams. Phosphates are essential to aquatic plant growth, but too much phosphate can lead to the growth of algae and results in an algae bloom. Too much algae can cause a decrease in the amount in dissolved oxygen in the water. Oxygen in water is affected in many different ways by phosphates Phosphorus is usually present in natural waters as phosphate(Mcwelsh and Raintree, 1998). Phosphates are present in fertilizers and laundry detergents
The Brown Pigment The brown colour of brown algae is due to presence of green pigment (chlorophyll a and c) and the brown fu-coxanthine. The seaweeds which live in deep water absorb different wavelength of light due to the presence of these different types of pigments and manufacture their food by the process of photosynthesis. Laminarin, a unique type of starch, is produced in brown algae. Examples of Brown Seaweeds 1. Kelp Sea bamboo (Ecklonia maxima), the spilt fan kelp (Laminaria pallida)
My Aquarium The place I decided to do my paper on is located in the living room of my family’s house. It is a one hundred gallon aquarium. The reason I chose this as the topic of my paper is that all kingdoms are present except for Plantae in it and it is its own ecosystem. Before I go in detail about the organisms in the aquarium, I would like to mention the accessories that make this aquarium a stable environment and allow the organisms to grow happily. The temperature needs to mimic
phosphorous. It caused the algae in the water get a faster reproduction, with the increasing number of algae, these algae will secrete thin blue-green or red-yellow films, and it’s seriously influenced the growth of fish. Although there are many algae, but there are not enough nutritive salt for algae living. When the nutritive run out, the algae would die. But after the mass of algae dead, much oxygen in the water be used to resolve their corpse, the corpse will formed a green film, and made the water
The purpose of this project was to determine if algae would produce more energy than sunflower oil and canola oil. The hypothesis was that algae would produce more energy. The type of algae that was used for the experiment was chlorella. The project experiment involved growing algae in water which was placed under a carbon dioxide tank. The algae required a 12 hour light cycle per day to grow efficiently. Once grown, the algae was placed into a bomb calorimeter to measure the amount of heat energy
There are many different species of algae. One of the most common algae, blue-green algae, is a type of cyanobacteria. One species of this is the Chlorella regularis, single celled algae that stays alive through the process of photosynthesis. The growth of algae depends on a variety of factors, such as the nutrients in that environment, temperature, light levels, turbidity, and stable conditions (Department of Primary Industries, 2009). The mass growth of algae is known as an algal bloom. This large
Investigating Pleurococcus Plan Pleurococcus is a green, single-celled algae that is found on the bark of trees, where it survives better on the north side of the tree and near the ground. It can also be found on stones and fences and usually in moist situations. As it is a green plant, as all green plants do - it photosynthesises. The chemical reaction that is taking place is: [IMAGE] Carbon Dioxide + Water Glucose + Oxygen light [IMAGE] Chlorophyll [IMAGE]6CO2
reproduction, lifespan, behavior, food habits, predation and threats to Parrotfish. Additionally, this paper will examine the importance of this species to the coral reef ecosystems in the Caribbean. Scaridae: The Parrotfish Family The colorful, algae-eating, sand-pooping, Parrotfish is the most
photosynthetic organisms, organic pigments exist to harvest the light energy. The three major classes of pigments are chlorophylls (green pigments) and carotenoids (yellow or orange pigments) which are lipophilic and associated in Chl-protein complexes as well as phycobilins that are hydrophilic. All chlorophylls (a, b, c and d) have two major absorption bands: blue or blue-green (450 or 475 nm) and red (630-675 nm). Chl a is present in all oxygenic photoautotrophs as part of the core and reaction centre
Introduction Fossil records indicate life has existed on this planet for at least 3.8 billion years. Most species that have ever existed are now extinct, yet the diversity of life on Earth is still so tremendous and complex scientists estimate there are 10-100 million species yet to be documented. Those that have been documented, have been categorized it into three domains, six kingdoms, twenty-nine phyla, and countless more subdivisions. Seemingly in spite of this diversity, a common ancestry unites
