Cyanobacteria Cyanobacteria are one of the largest and most important groups of bacteria on the earth. Often called ‘the blue-green algae’ Cyanobacteria is in fact, not an algae at all. Algae are eukaryotic, whereas cyanobacteria, is a bacteria, and is prokaryotic. The name algae is used to refer to any aquatic organisms capable of photosynthesis, so the term is considered general, though in this case, inaccurate. Being tiny and normally unicellular, cyanobacteria grow in large colonies, making them
Cyanobacteria (blue-green algae) Cyanobacteria, also known as Blue-green algae, (Cyanophyta), (Myxophyta) and (Cyanochloronta) are difficult to classify, and there are numerous schools of thought on their Taxonomy. Cyanobacteria are prokaryotic organisms however posess many of the same qualities as algae and therefore were previously categorized as such, hence the name blue-green algae. They form a class greatly dissimilar from that of other algae, and possess many of the same characteristics of
what effect agricultural runoff has on surrounding environment, and to find what solutions can be made to reverse any damage. Introduction: 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
Biotic Components: Animals which get nutrients, accomplish digestion, yield vigor, and can transfer nearby in the environs are biotic. They can produce, replicate, continue homeostasis, familiarize, and grow. Abiotic Components: The abiotic mechanisms comprise the vitality twisted over the pedaling of nutrients, the stellar dynamism, and other dead mechanisms in the environment. The abiotic constituents of the system can be hotness, sunlit, airborne existing, etc. Limiting factors: To one side after
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. Due to the unfair advantage cyanobacteria has over other non-nitrogen-fixing species and its cause in oxygen depletion, other
2. A stromatolite is a fossil of blue green algae, or cyanobacteria. They date back up to 3.5 billion years ago, and made other life possible by transforming earth’s atmosphere to one much more suited for terrestrial life, by creating oxygen gas. 3. Archean life was extremely basic, essentially making it harder for anything to go wrong with it. Life first appeared in an incredibly hostile environment, todays earth is much more hospitable and abundant with all sorts of life. 4. The Paleozoic era

The first 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
Diatoms are a unicellular phytoplankton that survives by floating in the ocean and are in the class Bacillariophyta. Diatoms are even the most common type of life in the ocean. This organism is similar to plants because of the photosynthetic qualities they posses. Diatoms use photosynthesis to absorb light, yet the pigment they possess is brown. Such aspects relate diatoms to brown algae. For this reason, scientists typically place them in the plant kingdom but others state today they are in the
Lichen Bright and neutral colors of crumbly material sit upon a boulder that beckons to be noticed. A small child places its hand upon the rock and notices upon withdrawal that small bits of an unknown substance come back, stuck upon the palm. Many people are unaware that this strange substance, called lichen, is actually a plant and thrives and lives upon that boulder. Lichen is a special kind of plant that has its own unique biology, has many different types and classifications, and heavily
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)
I. Objective: How does the rate of photosynthesis affect the plant? II. Background Research: The Elodea plant (scientific names: Egeria densa, Egeria brasiliensis) has dark green leaves that become crowded toward the top. The Elodea plant grows in a variety of pond habitats but prefers to grow at the bottom of cool ponds. Elodea plants can remain green all winter long. . Water is one of the factors that affect photosynthesis. A shortage of water can slow down or even stop photosynthesis. Temperature
Toxic Algae bloom Name: Faisal Hussain Student number: 500635004 Course code: ENH 617 Institution: Ryerson University Submission Date: 16th November 2015 Word Count: 537 Toxic Algae bloom Freshwater and marine destructive algal blooms also called harmful algal bloom or HABs, can transpire anytime, and use of water is impaired due to the accumulation of excessive harmful algae. HAB instance is influenced by an intricate set of chemical, physical, hydrological, biological, and meteorological
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
small aquatic bacteria, such as cyanobacteria and Halobacterium halobium. Biomarkers indicate organisms similar to cyanobacteria were present 2.7 billion years ago [5], and other archaeological fossils have been shown as evidence of photosynthesis at this early stage of Earth’s development. Cyanobacteria, like modern plants, use the energy of the sun to power their photosynthesis, and can photosynthesise in both aerobic and anaerobic conditions. [6] Cyanobacteria were one of the first organisms
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
rhythm is sleep but other examples include, body temperature, blood pressure, production of hormones and digestive secretions. These rhythms do not only take place in humans but are present in a wide variety of other organisms, the simplest being cyanobacteria. Circadian rhythms are usually controlled by a combination environmental factors and internal factors. The most common environmental factors are temperature and light. Circadian rhythms are controlled by a circadian pacemaker, or a biological
Ethanol production was developed in hopes of severing our ties with fossil fuels in favor of alternative energy, such as biofuels. Although, VOCs emissions are released during production of ethanol in a factory, the quality of air is greatly improved when burning ethanol versus fossil fuels. Burning ethanol instead of fossil fuels reduces the amount of cancer-causing greenhouse gases that go into the atmosphere. Ethanol production ranks at the bottom of industrial water usage, but is still not out
Abstract: Ladakh is a high-elevation cold desert, which makes it an extraordinary extreme environment. It provides a suitable habitat some wildly adapted microbes. Due to the high elevation a person can experience freezing cold temperatures and the burning nuisance of the sun all the same time. There is an abundance of cold adapted microbes in Ladakh, some which are thought to have application as inoculants and biocontrol agents in crops not only growing at low temperatures but at high elevation
vertically (Debashish et al., 2003). The evolutionary history of plants involves at least two independent endosymbiotic events (as shown in Figure 1); because plastids such as chloroplast evolved when a primary endosymbiotic event caused photosynthetic cyanobacteria to be engulfed by some non-photosynthetic host cells (Dyall et al., 2004). Chlorophyta, Rhodophyta and Glaucophyta are three clades, belonging to the group Archaeplas... ... middle of paper ... ...n, P.J., 2004. Ancient Invasions: From Endosymbionts
Nostocales are the tropical species C. raciborskii and Aph. Ovalisporum. Numerous reports have been filed from all over the world about the invasion of cyanobacteria. Studies with isolated strands of cyanobacteria have shown that invasive species have robust competitive abilities under changing environments. Under lower temperature native cyanobacteria outcompete the invasive species but under high temperatures invasive species outcompeted the native stand. The authors could demonstrate that with increase
