The text by Smith S.E & Read D.J recorded that in 1885 Frank A.B invented the word ‘Mycorrhizae’ which is a literal synonym of fungus-root. Many people tend to think of mushrooms and toadstools when it comes to the word fungus but it can also be found in decaying material and plant tissue within the soil where the fungus’s biomass is made up of a large scale of hyphae filaments. This is the main mode of vegetation growth. This system is known as Frank A.B invention ‘mycorrhizae’ and is a vital role in the functioning of the earth's ecosystem. Mycorrhizae is a fungus that grows inside or attached to the surface with the roots of a plant. By the action of the fungus and roots of a plant connecting, LaFantasie J. describes on her lesson that by …show more content…
A pathogen can be anything that causes a disease, including bacterium which causes meningitis, Viruses causing hepatitis A-C, and a fungus that cause athlete's foot. Plant pathology bacteria can serve economically damaging diseases, from spots, pustules on leaves and fruit, tuber rots to a plant's death. Some bacteria causes a hormone base distortion of leaves and shoots called fasciation. Fungi pathogens spread through plants to steal nutrients of living plants and carry out the part of the life cycle in soil. Mycorrhizae fungi make carbohydrates from plant roots, enhancing plant uptake of inorganic nutrients such as phosphorus and nitrogen. Cripps, C.L reported on mycorrhizae that “ The relationship is considered nonpathogenic, and of benefit to the plants involved.”- describing that the relationship between mycorrhizae and pathogens is nonpathogenic because mycorrhizae cancels out the disease. Over 85% of plants in nature have the mycorrhizae condition to keep pathogens away. This is why gardeners buy mycorrhizae fungi to help stop diseases of plants and for the safety of humans catching the disease through eating the plants. Food is one of the most important factors in the ecology life cycle and mycorrhizae makes it safe for these plants to take part in the …show more content…
China is becoming one of the increasingly crucial environmental concerns of heavy metal contamination on agricultural land. Heavy metal contamination happens when water resources are short and wastewater is then applied to plants causing major health risks to environmental quality and food production. Many scientists have been exploring solutions of this environmental problem and some research say that mycorrhizae have made a positive outcome in fighting the heavy metals and toxins in the soil. Heggo,A. (1990) studied the mechanism of mycorrhizae and heavy metals and resulted that mycorrhizae fungi may filter excessive metals in the soil. Another study showed that mycorrhizae enhanced tolerance of plants infected with toxic soils. Scientists are still studying to find out ways how mycorrhizae fungi improve these plants and resistance from heavy metals. However, metal and toxin uptake might be also impacted from the soils condition. Mycorrhizae symbiosis are well familiar for their enhancement of phosphorus uptake. This nutritional benefit is questioned to account for the plants tolerance of heavy metals and toxins in the soil. The way that heavy metals and toxins affect the ecosystem is the life of organisms such as plants don’t grow in a healthy manner causing toxic plants where animals and humans can
Tropicalia is not only know as a form of music in Brazil but as a rebellion. Its theme of cultural non conformity was strengthened by the idea that Brazil had lost its way. Tropicalia took a stand against the social and musical hierarchy of Brazil. Though mainly known as a form of Brazilian pop music Tropicalia is deeply rooted in the political and cultural background of Brazil.
Is being numinous more satisfying when you don't have moral concepts to add on to that belief?
Cyntoia had a rough life. When Gina, cyntoia's biological mother got pregnant she was a teenager and was not in the right state of mind to even take care of a kid. She didn't even know how to make a bottle plus she was drinking throughout her pregnancy and then she was introduced to crack cocaine and dropped the drinking. She wanted to escape her responsibilities and this is why they made her mother give cyntoia up for adoption. Cyntoia has a sex list. She kept track of how many times she had sex and what times she wanted it and when the other she didn't want at all. She had sex with 21 people out of the 36 where she just felt like she had to do it. 22 out of the 36
The first step of the process of hay production is the standing crop. The standing crops contain bacteria and yeasts. This is where potential mold growth begins (Smith). Once the crop has been cut the moisture of the plant is then decreased very quickly. This now allows a new group of microbes to begin to reproduce and spread. Hay that is apparently dusty but lacks visual evidence of mold, is caused by fungi growing in the cut hay that is drying out in the field. After the hay has been baled, yet another new group of microbes (mainly consisting of fungi and yeasts) start to reproduce (Smith). These new fungi are better suited to fill this new, drier, and warmer niche. The most common molds found in hay include Alternaria, Aspergillus, Cladosporum, Fusarium, Mucor, Penicillium, and Rhizopus each of these types cause spores that can cause problems for livestock and especially horses (Lemus). Out of these common types of fungi, there are three types that start to grow mainly during storage; These are Aspergillis, Fusarium and Penicillium. Several of the fungi that grow during the hay bale storage process are known to produce mycotoxins. These are the organisms that feed off sugars and organic acids emitted from the plant during the drying process and they are also the types of fungi that cause hay to become moldy (Smit...
he Water Hyacinth is an invasive species that seems to be causing problems to local rivers and ponds. What are an invasive species you may be wondering? An invasive species is a species that is not native to a specific location and can cause damage to an ecosystem. The water hyacinth is a free-floating perennial plant that can grow to a height of 3 feet. The plants have a tendency to spread at a rapid pace and often times grow thick mats above the water. Under these mats, the plants have a thick root system. The water hyacinth is a very beautiful plant but it causes many problems. This plant, again, forms very thick mats on top of the water’s surface which if it covers the entire surface, it can cause oxygen depletions for fish and other animals under the mats and eventually kill the. They reproduce very quickly and tend

The Artemia franciscana can survive in extreme conditions of salinity, water depth, and temperature (Biology 108 laboratory manual, 2010), but do A. franciscana prefer these conditions or do they simply cope with their surroundings? This experiment explored the extent of the A. franciscanas preference towards three major stimuli: light, temperature, and acidity. A. franciscana are able to endure extreme temperature ranges from 6 ̊ C to 40 ̊ C, however since their optimal temperature for breeding is about room temperature it can be inferred that the A. franciscana will prefer this over other temperatures (Al Dhaheri and Drew, 2003). This is much the same in regards to acidity as Artemia franciscana, in general thrive in saline lakes, can survive pH ranges between 7 and 10 with 8 being ideal for cysts(eggs) to hatch (Al Dhaheri and Drew, 2003). Based on this fact alone the tested A. franciscana should show preference to higher pH levels. In nature A. franciscana feed by scraping food, such as algae, of rocks and can be classified as a bottom feeder; with this said, A. franciscana are usually located in shallow waters. In respect to the preference of light intensity, A. franciscana can be hypothesized to respond to light erratically (Fox, 2001; Al Dhaheri and Drew, 2003). Using these predictions, and the results of the experimentation on the A. franciscana and stimuli, we will be able to determine their preference towards light, temperature, and pH.
The book Where The Red Fern Grows written by Wilson Rawls was made in 1961. Then the movie came out in 1974. In my personal opinion the book is better but that's just me. The reason i like the book better is because it has more detail i feel like the movie went by way too fast. Where The Red Fern Grows is about a little boy who wants some coonhounds and when he finally gets them he raises them into some of the best hounds.
Sordaria fimicola belongs to the kingdom of fungi and is part of the phylum Ascosmycota. This fungus habitat is in the feces of herbivores. As many fungi Sordaria have one life cycles which is haploid/ diploid. It is commonly exits as a haploid organism, but when the mycelium from two individuals meets, the result is a diploid zygote. This diploid zygote which undergoes meiosis forms eight haploid ascospores . The ability of Sordaria to make 8 haploid ascospores is what makes it unique and important for the laboratory exercise done in lab.
Animals ingested the fungus, including spores. The host’s immune system could destroy the fungus. Once the host has died, the mutations could lead to spores.
Corbicula fluminea is a freshwater species of clam that is invasive to the United States. This clam is often used as a food source in the Asian countries to which it is native, and is postulated to have been introduced in the late 1930s to the state of Washington by Chinese immigrants (Dresler 1980). C. fluminea has since spread throughout the majority of the U.S., and has become particularly prolific in the Chesapeake Bay region since the 1970s (Dresler 1980).
Some say they've seen vampires before, others say they're crazy but it just could possibly be the truth. Porphyria is the deficiency or inactivity of a specific enzyme in the heme production process. Porphyria effects different people in different ways. It is also the origin of the myth of vampires. Since there is no actual recording of vampires, this disease is the only thing that could make a person vampire-like. There are two main types of Porphyria; Acute Intermittent Porphyria and Cutaneous Porphyria. Both of which have negative effects that will affect a person badly. Porphyria effects the the body externally, internally, and family.
Fungi are eukaryotic organisms which are either single-celled or multi-cellular organisms, their DNA containing chromosomes are enclosed in a Nucleus inside their cells. Fungi cell structure is very similar to that of the plants however, Fungi do not perform photosynthesis. Fungi is often known to be a nuisance when found within a person’s house, whether on food, the walls or even the floor. People naturally find it disturbing and dirty, however there are good types of Fungi, often referred to as friendly fungi. In 1928 Penicillin, one of the most famous of antibiotic drugs was discovered having derived it from the fungi called Penicillium. This discovery has since has a huge impact on helping people across the globe. However, not all is it seems, there are some nasty fungi that can cause diseases in plants, animals and people. A famous one being Phytophthora infestans. This ...
Very few view fungi as essential to human life. If asked to consider this diverse kingdom, most would only answer with whether they enjoy mushrooms on their pizzanotwithstanding the fact that there are at the very least 1 million species of fungi thought to outnumber vascular plants by a ratio somewhere between six to one and thirty-three to one. Even so, only 100,000 species of fungi are known to exist while mycologists continue to discover 1000 new species every year. Most notable was the recent discovery of a single honey mushroom congregation thought to weigh 605 tons and cover 2200 acres of Oregon’s Strawberry Mountains. If considered a single organism, this 2000-year-old fungus would have the largest surface area in the world (Stephenson 2010). As a result of this diversity, fungi form a complex and captivating clade that supports a large portion of Earth’s life.
in accessible frame, micronutrients, microflora, compounds, and development controllers [C. A. Edwards( 2004), A. A. Ansari( 2011) ]. Along these lines, the vermicompost when connected or supplemented in soil enhances trim development and yield [J. G. Zaller et al.(2007) , M. Jayakumar et al.(2011)]. The night crawlers, the drivers of many procedures in soil, aside from the known vermicomposting, are likewise found to improve phytoextraction of metals from sullied soils [R. K. Sinha et al.(2010)]. Moreover, vermicompost, delivered by the joint activity of earthworm and microorganisms, contains supplements in accessible shape with expanded microbial action [M. Aira et al (2007)] . The utilization of biofertilizers is these days known to draw out a few advantages to soil: solubilization of basic minerals, get hold of supplements, offering micronutrients in more utilizable shape for plants, and partaking in organic nitrogen obsession. Microorganisms of this gathering are for the most part known as plant development
