Fungi break down nutrients in the environment and then use absorption to take in the nutrients. Plants make their food by carrying out photosynthesis. This difference was the basis for changing the way in which each group of organisms was classified. What was the main criterion used to classify these two types of organisms

Explanation:

Photosynthesis

Photosynthesis or chlorophyll function is the conversion of inorganic matter to organic matter thanks to the energy provided by light. In this process, light energy is transformed into stable chemical energy, with NADPH (nicotine adenine dinucleotide phosphate) and ATP (adenosine triphosphate) being the first molecules in which this chemical energy is stored. Subsequently, the reducing power of NADPH and the energy potential of the phosphate group of ATP are used for the synthesis of carbohydrates from the reduction of carbon dioxide. Life on our planet is maintained fundamentally thanks to the photosynthesis that algae, cyanobacteria, red bacteria, purple bacteria, green sulfur bacteria, and in the terrestrial environment plants, which have the ability to carry out in the aquatic environment. synthesize organic matter (essential for the constitution of living beings) starting from light and inorganic matter. In fact, every year photosynthetic organisms set about 100 billion tons of carbon in the form of organic matter.

decomposition of fungi:

Fungi are eukaryotic and saprotrophic organisms, that is, they feed on dead organic matter: remains of plants and animals, waste substances, synthetic products and any soluble element that diffuses in the environment. They need carbon compounds rich in energy made by other organisms; They are decomposers par excellence fulfilling a very important role in the cycles of nutrients together with bacteria, actinomycetes and protozoa.

Any fungal species is capable of breaking down only certain organic compounds (cellulose, chitin, keratin, lignin, proteins, hydrocarbons, etc.) and a certain number of microorganisms including bacteria and protozoa, are required to carry out the complete decomposition of the residue. , there is a sequence that depends on your nutritional skills. Some species begin the decomposition process, but their activity stops due to the accumulation of certain metabolites (products of metabolism) or the inability to continue splitting due to lack of suitable enzymes, being replaced by others that continue and finish the process.

Likewise, fungi can live at the expense of living tissues of an organism, absorbing sugars and simple amino acids from the living cells of the host (biotrophs), so they cause diseases; or they cause death by toxins or the destruction of tissues by enzymes and then use organic matter (necrotrophs). They can also exchange substances by associating with other organisms (symbiosis), such as cyanobacteria or green algae to form lichens, or they can be found in the soil linked to higher plant roots, forming mycorrhizae.

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20

sulfhydryl -sh

thiols, cross-linking stabilize the protein, and it is structure
