Characteristics: They are Eukaryotes cells without chlorophyll and chloroplasts. X heterotrophic organisms are so form one kingdom to the kingdom of fungi.
They can be microscopic and macroscopic.
Can be found in different media in the soil, water, remains of plants or animals or organisms also parasitizing living organisms.
Structure: There are two types:
-Levuriforme: K is unicellular
-Meceliar: K are multicellular.
* Levuriforme: These are organisms known as yeasts, are typical cell organelles Eukaryotes with usual but with some characteristics tend to be elongated, plasma membrane invaginations present in some cases-like vesicles. In some cases it also appears cell wall.
* Mushroom spawn: Made x elongated filaments called hyphae, these structures consist of a cell wall and different cells can be separated k k are called non-septate hyphae.
"Role of Nutrition: Organisms are fed k from k organic matter found in the environment or other living organisms (heterotrophs). They may be saprophytes if they feed on organic matter from the remains of animal and plant organisms that are decomposers x or parasites if they use organic material of living organisms.
There are two types of digestion k fungi do in case of unicellular ongos h: Digestion is internal, when introducing the food and make digestion lysosomes. In the case of multicellular fungi: The digestive enzymes is discharged to the environment external leads outside last yx absorbs nutrients.
In the absence of oxygen, some species of fungi fermentations performed are produced inside the cells when degrades carbohydrates for energy, as a final product obtained alcohol IE: used to produce wine and beer.
Role-Playing: The fungi reproduce by spores, are k cells derive from stem structure. The spores can be sexual and asexual they can switch within the life cycle of the fungus. A life cycle are all k processes are given from the formation of the zygote until k play back again.
When environmental conditions are favorable for the fungus produce large quantities of spores and asexual mitotic divisions that give rise to identical individuals between them and the parent fungus. When environmental conditions are unfavorable Miosis performs the fungus is a type of cell division girders which haploid spores obtained ie cells with half the chromosomes but all the genetic information.
These spores in turn generate haploid gametes developed, they will join other Gametes Gametes produced x another fungus of the same species.
Gametes of the union of diploid zygote is obtained as k was developed according to their life cycle or environmental conditions.
Infectious diseases are caused x fungi. They are opportunistic organisms that is uses a weak immune system to infect (infants, elderly ...)
We'll talk about two kinds of genres k cause infectious disease:
"The Condidiasis: No infections caused x Candida species, affecting the skin and mucous membranes. + Common species is Candida albicans is a fungus can attack k the oral cavity, the digestive tract and vagina.
K types of infections can cause this kind are:
1.Aftas: x They feature a white patches on the oral mucosa is typical for premature infants and the elderly with other diseases.
2.Onicomicasis: k is an infection occurs in the nails of hands and feet, features red x in the training base of the nail k is painful.
Vaginal 3.Condidiasis: It is typical of pregnant women or women treated with antibiotics, this infection causes itching and whitish discharge.
4.Condidiasis intertriginous: They are a type of fungus k affecting the skin folds and in the chest, buttocks, between fingers ...
-Tubs: k dermatological fungi are characterized by causing superficial infections. Tissues infected with keratin (Piola, nails ...)
1.Tiñas of the feet or athlete's foot: It attacks the spaces between the toes, and sometimes causes cracks vesicles, x can be extended across the sole of feet. It is spread from contaminated water girders x this fungus, especially when the skin is damaged or weakened. As prevention is avoiding contact k (use flip-flops)
2.Tiña of nails: Usually accompany ringworm of the feet, is a complication of another infection. It causes a thickening of the nail and may eventually fall.
3.Tiña Hair: Common in young children. There are different types, the usual + k generates is bald (skin peels and hair falls out) Treatment is with a special cream for yeast (antifungal).
