Fungi live as either single-celled organisms or multicellular organisms. Single-celled fungi are referred to as yeasts. The vast majority of fungi are multicellular. Most of the body of a fungi is made from a network of long, thin filaments called 'hyphae' ( this is a hyphae)

fungus, plural fungi, any of about 144,000 known species of organisms of the kingdom Fungi, which includes the yeasts, rusts, smuts, mildews, molds, and mushrooms. There are also many funguslike organisms, including slime molds and oomycetes (water molds), that do not belong to kingdom Fungi but are often called fungi. Many of these funguslike organisms are included in the kingdom Chromista. Fungi are among the most widely distributed organisms on Earth and are of great environmental and medical importance. Many fungi are free-living in soil or water; others form parasitic or symbiotic relationships with plants or animals.

Fungi are eukaryotic organisms; i.e., their cells contain membrane-bound organelles and clearly defined nuclei. Historically, fungi were included in the plant kingdom; however, because fungi lack chlorophyll and are distinguished by unique structural and physiological features (i.e., components of the cell wall and cell membrane), they have been separated from plants. In addition, fungi are clearly distinguished from all other living organisms, including animals, by their principal modes of vegetative growth and nutrient intake. Fungi grow from the tips of filaments (hyphae) that make up the bodies of the organisms ( mycelia), and they digest organic matter externally before absorbing it into their mycelia.

While mushrooms and toadstools (poisonous mushrooms) are by no means the most numerous or economically significant fungi, they are the most easily recognized. The Latin word for mushroom, fungus (plural fungi), has come to stand for the whole group. Similarly, the study of fungi is known as mycology-a broad application of the Greek word for mushroom, mykēs. Fungi other than mushrooms are sometimes collectively called molds, although this term is better restricted to fungi of the sort represented by bread mold. (For information about slime molds, which exhibit features of both the animal and the fungal worlds, see protist.)

Q )How symbiotic relation between fungi and plants help in increasing crop yield?

A) Most crops can form symbiosis with fungi to gain key nutrients. The fungi in turn gain carbohydrates generated through the plant's photosynthesis. This type of symbiosis is called arbuscular mycorrhizas and is of key importance to sustainable agriculture since it helps crops utilise better the phosphate in fertilisers

Mycorrhizae are symbiotic relationships that form between fungi and plants. The fungi colonize the root system of a host plant, providing increased water and nutrient absorption capabilities while the plant provides the fungus with carbohydrates formed from photosynthesis.

The fungus grows in or on the plant roots. The fungus benefits from the easy access to food made by the plant. The plant benefits because the fungus puts out mycelia that help absorb water and nutrients. Scientists think that a symbiotic relationship such as this may have allowed plants to first colonize the land

Aerobic respiration, it is a type of respiration in which oxygen is required and they release carbon dioxide+ water (+energy).

For yeast to undergo aerobic respiration; bread dough is stretched and folded to get air, then the yeast cells respire aerobically and bubbles of gas make the dough rise. This is also what cause the dough to rise.

Anaerobic respiration, it is a type of respiration in which not a lot of oxygen is required. The anaerobic respiration of microorganisms is called fermentation.

In yeast, this type of respiration produces ethanol.  Plants can also use this type of respiration.

Mushrooms are considered as decomposers because they feed on dead or decaying organisms. This process involves the fungi breaking down the organism into smaller parts which they can intake.  This removes litter (decaying organisms) on the ground and keeps the ground clean.

Why UAE considers Quinoa is considered as  the future of food?

# data[].attributes.attachment_link.readable_text
Dubai: What can you grow in a land of scorching summer, poor soil, and scarce water? One answer, as the UAE's climate change ministry claims, is quinoa.

Both rich in nutrients and able to grow in harsh, arid climates, officials believe that quinoa could be commercially viable within five years.

"Currently, it looks like there's really good potential ... within the next five years to have the crop on the ground," said Majid Sultan Al Qasimi, a director at the Ministry of Climate Change and Environment.

The grain, which contains more protein than rice and wheat, and nutrients including essential amino acids, fibre, minerals and vitamins, is sometimes referred to as a 'superfood'.

In the UAE, which produces little of its own food, officials believe the crop could help the nation's food security.

In 2013, the UAE's climate change ministry - then known as the environment ministry - first began growing quinoa on home soil.

Several months later, the experiment yielded a crop of 4.5 tonnes - roughly enough to give 75,000 people a small, salad-topping sized portion.

But there's work left to do - such as working with farmers long used to growing date palms and vegetables.

"For us, what is important is to get the buy-in of the farmer," Al Qasimi told Gulf News on the sidelines of a Dubai conference dedicated to the crop.

"We're not here to persuade them and [then] them reluctantly trying. What we're trying to do here is educate the farmer [and] show them the potential of the crop."

Quinoa is known for its ability to grow in a wide variety of climates, and can withstand a wide range of daily temperatures - from 0 degree Celsius up to 30C. Its tolerance to salty water makes it suitable for growing in the UAE, which has to desalinate most of its water.

Quinoa's versatility and rising demand have led many countries to grow the crop. In Pakistan, traders claim that due to cheaper labour and logistics, producing the crop costs half as much as in South America.

Quinoa quandary

The push towards growing Quinoa in the UAE has been a decade in the making. Since 2006, experts at the Dubai-based International Centre for Biosaline Agriculture has been growing and studying quinoa in the country.

Getting locals to want to eat Quinoa is another challenge - but a necessary one in an era of soaring diabetes rates and medical costs, according to Ismahane Elouafi, the centre's director-general.

"If I go right now to any supermarket, the quinoa is there, and it is sold, so there is a market [for it]," said the Moroccan-Canadian scientist.

"But my feeling is that it's mostly for the expats. So what you need to do is really bring the locals to be interested in quinoa."

What is quinoa?

Once the humble staple of poor South American farmers, Quinoa has become a hit with wealthy Western dieters and health-food fanatics who revere its high protein, zero-gluten properties.

The beige-coloured grain's surging popularity as both a 'superfood' and sustainable crop led the United Nations to declare 2013 as the 'International Year of Quinoa.'

Around the same time, the grain started to crop up in salad bars and cafés across the West. By 2015, even fast-food stalwart McDonald's started to include Quinoa on some menus.

UAE officials are interested in Quinoa due to its ability to grow in high heat and arid soil. It also requires little water to grow - and can adapt to very salty water.

Yeast is a single-celled fungus. It is able to ferment sugar, producing alcohol and carbon dioxide in the process. It has long been used to make beer and wine as well as bread (the carbon dioxide causes the dough to rise).

Yeasts are used in the fermentation of fruits to produce wines, cereals to make beer, in bread manufacture and flavoring in the form of yeast extract. Filamentous fungi are used in traditional processes for the ripening of cheeses and in the production of enzymes used in the food industries
