Despre ciuperci
pagina realizata de Irina**



Ciupercile, cu aproape 100 000 de specii, au o mare raspandire pe suprafata pamantului. Ele sunt plante talofite unicelare si plurileculare. Corpul vegetativ al ciupercilorsau miceliu este format din filamente simple sau ramificate, numite hife. Fiind lipsite de pigmenti asimilatori, cupercile sunt saprofite si parazite.

Ciupercile saprofite se hranesc cu substante organice in descompunere si au o mare importanta practica. Mucegaiul alb este caracterizat prin hife in forma de tuburi lungi, cu citoplasma si numerosi nuclei, dar nedespartite in celule. Mucegaiul alb de pe alimente are miceliu foarte ramificat si intins ca o pasla laxa pe suprafata mediului nutritiv. Itr-o schema rezumatica se poate urmari ciclul evolutiv al acestei cuperci, cu inmultirea asexuata prin sporii din sporangii sferici.

Mucegaiul verde sau galbui are ramurile sporifere ramificate in forma de pensula. Din Penicillium notatum, ca si din alte specii se obtine penicilina.

Drojdia de bere este o ciuperca ascomiceta unicelulara, ce provoaca fermentatia hexozelor cu producerea de alcool si bioxid de carbon. Pe langa inmultirea prin inmugurire, mai produce ascospori intr-o celula numita asca. Are o larga intrebuintare la dospitul aluatului si la fabricarea berii. O ciuperca asemanatoare, dar cu celulele mai alungite, este drojdia vinului folosita in indrustia alcoolului.
