same between two red algae, or two green algae. In this lab a red, green and brown algae will be used to extract the photosynthetic pigments from. We will also be extracting the photosynthetic pigments from Coleus sp., which is a red land plant leaf and, and compare the accessory pigments of this to the red algae. Methods and Materials We used two different kinds of red algae for this experiment. The first was Polysiphonia sp. and the second Porphyra sp. The green algae were Entreromorpha
Introduction Red Tide, 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
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

Resources I. Harmful Algae All algal species are not harmful. Only a few out of the thousands of species are associated with the phenomenon known as an algal bloom. These algae fall into two categories. The first category of harmful algae produces toxins that are
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)
Red tides have made many people sick such as residents and tourists of Florida’s Gulf Coast. The tides also have affected many business owners because many tourists don’t want to come to beach resorts because of Red tides. Red tides are caused by two ways. One of the ways are the algae reproducing and giving an effect of toxic air. Many outbreaks have also occurred because of red tides. Such of these things include poising form fish and shellfish. To stop Red tides, many researchers have done numerous
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
HYPOTHESIS ========== I predict that the order of best absorption in a plat to produce more bubbles will be blue, yellow, orange, red and finally green. I predict this because blue has the shortest wavelength which produces the most energy and there is slightly higher absorption in the blue region by the plant. The red has the largest wavelength in the visible spectrum which produces the least energy. The reason why green is at the bottom of the list of absorption
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
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
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
a plant nutrients, especially nitrogen and 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
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
The Red Tide The Red is a algae bloom that releases toxins into the ocean and releases horrid smells that can leave you with respiratory problems like hacking horribly, minor cough , or asthma in worse cases. The algae bloom releases toxins when its in a high concentrated state into the ocean that the shellfish take in but they don’t die. Instead they concentrate all of it into their body’s in a small space and if a human eats the shellfish the human has a huge chance of dying because of the toxin
Some diatoms are benthic and live on mud, seaweed, and other surfaces. Other diatoms are wholly plankton and float in the water column. What type of adaptations do you expect each type of diatom to have? In other words, how do some diatoms stay afloat, while others stay attached to the benthos? Some of the diatoms are able to stay afloat because they have more surface area, meaning they have extended body parts that catch the water and make them sink much slower. While other types of diatoms
Metropolitan University in 2013. Written works on marine research conducted by Earle includes books such as Seaweeds of the Gulf of Mexico and The Panamic Biota: Some Observations Prior to a Sea-Level Canal, regarding the protection and preservation of algae and marine life within the pacific. Seaweeds of the Gulf of Mexico outlines the importance of protozoa in the gulf of Mexico and the lengths at which they may be protected. As Quoted from the text, “Our understanding of algal phylogeny has dramatically
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 pigment-protein complexes, and in light-harvesting antennae, it is accompanied by Chl b or Chl c. The accessory (antennae) pigments Chl b, c and d
A plant with opposite leaves, white to dark gold flowers in the spring, and tiny red berries in the fall, emerge to be the Amur Bush Honeysuckle. The root of the Honeysuckle is from birds planting the seeds. Amur Bush Honeysuckle is an extremely invasive plant species that was brought over from Asia, to southern Ohio in the late 1950s, however, it is a non-native species (harvard.edu, 1997). This plant grows at rapid speeds with a large ability to reseed. When Honeysuckle is planted it tends to
bred in captivity make up about 40% of the global marine ornamental trade. They are about 30 known species which are native to warmer waters and are found around tropical coral reefs; most of which live in the shallow waters of the Indian Ocean, the Red Sea, and the western Pacific. Description: These fishes are characterized by their bright yellow to orange color with three distinctive white bars across its body. They are among the most recognizable reef-dwellers. Their average length –as reported-
chloroplast came into being about one billion years ago when a single-celled protist and a cyanobacterium came together through endosymbiosis, and this first photosynthesizing eukaryotic lineage was the ancestor of land plants, green algae, and red algae. Cyanobacteria and algae endosymbionts have spread photosynthetic capabilities in such a broad range (Wernergreen). In other words, heterotrophic prokaryote cells had taken in autotrophic photosynthetic bacteria cells. The ingested cell continued to provide
