The plant body in algae is always a thallus. It is not differentiated in root, stem and leaves. Algae range in size from minute unicellular plants (less than 1 µ in diameter in some planktons) to very large highly differentiated multicellular forms e.g., some sea-weeds.
Their forms may be colonial (loose or integrated by inter-connections of protoplasmic strands), filamentous (branched or un-branched), septate (branched or un-branched), non-septate or branched, multinucleate siphonaceous tube where the nuclear divisions occur without usual septa formation.

Downy mildew of grapes refers to any of several types of oomycete microbes that are obligate parasites of plants. Downy mildews exclusively belong to Peronosporaceae. In commercial agriculture, they are a particular problem for growers of crucifers, grapes and vegetables that grow on vines. slide contains vivid descrition of the plant pathogen.
Fungi get their nutrition by absorbing organic compounds from the environment. Fungi are heterotrophic: they rely solely on carbon obtained from other organisms for their metabolism and nutrition. Fungi have evolved in a way that allows many of them to use a large variety of organic substrates for growth, including simple compounds such as nitrate, ammonia, acetate, or ethanol. Their mode of nutrition defines the role of fungi in their environment.
Fungi obtain nutrients in three different ways:
They decompose dead organic matter. A saprotroph is an organism that obtains its nutrients from non-living organic matter, usually dead and decaying plant or animal matter, by absorbing soluble organic compounds. Saprotrophic fungi play very important roles as recyclers in ecosystem energy flow and biogeochemical cycles. Saprophytic fungi, such as shiitake (Lentinula edodes) and oyster mushrooms (Pleurotus ostreatus), decompose dead plant and animal tissue by releasing enzymes from hyphal tips. In this way, they recycle organic materials back into the surrounding environment. Because of these abilities, fungi are the primary decomposers in forests.
They feed on living hosts. As parasites, fungi live in or on other organisms and get their nutrients from their host. Parasitic fungi use enzymes to break down living tissue, which may cause illness in the host. Disease-causing fungi are parasitic. Recall that parasitism is a type of symbiotic relationship between organisms of different species in which one, the parasite, benefits from a close association with the other, the host, which is harmed.
They live mutualistically with other organisms. Mutualistic fungi live harmlessly with other living organisms. Recall that mutualism is an interaction between individuals of two different species, in which both individuals benefit.

Studies on the mycorrhiza of Geodorum densiflorum (Lam.) Schltr. from Western...IOSR Journals
Mycorrhizal association of Geodorum densiflorum (Lam.) Schltr. an endangered terrestrial orchid
in the Western Ghats of Karnataka has been investigated. Anatomical studies of the fully grown orchid have
revealed the presence of the fungal coils in the cells of the pseudobulb and in the cortical region of the root,
indicating the continued association of the fungus with the plant. The degree of colonisation was extensive in the
root . Pure culture of the fungus associated with the underground parts of the plant was obtained and identified
as Rhizoctonia solani, a common mycorrhiza forming species with many orchids. The rhizosphere soil analysis
of the nutrients was carried out which revealed the decreased level of phosphate when compared to nitrogen
and potassium. Nutrient analysis supports the fact that mycorrhizal association occurs under the deficiency of
soil nutrients like phosphate.
IOSR Journal of Applied Chemistry (IOSR-JAC) is an open access international journal that provides rapid publication (within a month) of articles in all areas of applied chemistry and its applications. The journal welcomes publications of high quality papers on theoretical developments and practical applications in Chemical Science. Original research papers, state-of-the-art reviews, and high quality technical notes are invited for publications.
MYCORRHIZA - the symbiotic association of fungus and plants ,types and functionKirtiKathait
A fungus and a green plant have a symbiotic relationship known as a mycorrhiza. The fungus provides the plant with mineral nutrients, such as phosphorus, and water, while the plant produces organic molecules through photosynthesis and gives them to the fungus in the form of sugars or lipids.
this presentation is about mycorrhiza. it is a benefitial association between fungi and roots of higher plants. in this presentation we will study about mycorrhiza and its types etc.
Corporate Storytelling for Leaders and Business .pptxPankaj Kukreti
Storytelling is the process of using fact and narrative to communicate something to your audience.
in these Slides,
Corporate storytelling is not always believable (greenwashing) If we fill our sites with improbable stories of corporate benevolence and racially-diverse stock photos of people leaping in fields, maybe we can distract people from the reality.
There is not much difference in kids and advertising ideas. if they are yours, you will feel they are the best
here we will learn how to create and make impact stories to tell.
You're only limited by your imagination.
So For what you are waiting for
Unleash your inner storyteller.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
