Protoplast in fungal cell

*Entire cell excluding cell wall is called protoplast. *Striping the cell wall by means of mechanical,chemical and enzymatically. protoplasm. It is a colour less material comprising living part of cell. 1- Cell Membrane *Delicate,extremely thin and living membrane. *It invest all protoplast. *Cell membrane is pressed against cell wall / Hyphal cell. *Some occasional invagination. *it is a infolded pockets. Moore and McCleary 1951 work in Loma some s. 2- Cytoplasm With in the plasma membrane . There is a colour less Cytoplasm in which sap filled vacoules may occur uniform and homogenous. There are two type of cytoplasm. A- Organelles. *They are living part. *Living part specific function. *They are endoplasm reticolum, galgi body , vacoules and mitochondria. B- InChusions. *They are dead part. *No specific function and not essential for cell survival. *Store food ,pigments,oil drop secretory granoules. 3- Cell Organelles. Endoplasm Reticolum composed of microtubules by small granules . In many fungi ,endoplasm reticolum and vesicular irregular loose.

Structure of protoplast.

Structure of fungal cell.

Cell wall in fungal cell. 1-Cell wall is variable among different group of fungi and same group. 2-Majority lack of cellulose. 3-They contains chitin (Fungi,Cellulose). 4-Insects have chitin cell wall (C22H54N21)n. 5-Micro fibers make cell wall riged. 6-They run parallel. 7-Cheif chemical component of cell is poysacharides. 8-Some protein and lips also present. 9-Cell wall is a made of cellulos is called Oomycets. 10-It is obrious our present knowledge is incomplete about chemical composition of fungal cell wall. 11-Chitin wall is permeable to water and true solution

Classification of parasite on the bases of presence

(A) Ectoparasite. Ectoparasite.                                                     Thallus of fungus may grow on the external surface of host is called ectoparasite.                                                             (B) Endoparasite.                                                   Thallus of fungus may grow on the internal surface of host is called endoparasite.eg Puccini a , ustilage.                               

Classification of fungi on bases of mode of nutrition

Classification of fungi on the bases of mode of nutrition. There are two types of classification of fungi on the bases of mode of nutrition. 1-Saperophyte. Grow where dead organic matter abounds in substratun. And mode of nutrition is seprobic or saprophytic. 2-Parasite. Live in or on living bodies of other organism and obtain food from them is called parasite Mode parasitic The organism on which parasite feed is called host or suspect. The presence of parasite on the host may cause abnormal condition in host is called disease.

Nutrition in fungi.

1-They lack chlorophyll so 2-They cannot synthesis food like animal human etc. 3-They are different from green plants due to mode of nutrition. 4-They obtain food from external. 5-These fungi source are heterotrophs. And the mode of nutrition id called hetrotrophic. 7- They can not ingest food. 8-They absorb food. 9- fungi get their nutrition by absorbing organic compound in environment.

Fungi

Define: Non green flectulated thelopyhtes is called fungi. Fungi is a prulal of fungus.It is a latin ward of fungor.It mean flourish.It is a fast growth.These are a mash room. Thallus like a chlorophelous plant. funngi: genra:5100 spieses:50,000

Mycology and Mycologiest

The branch of botany which deals with study of fungi is called mycology.Mycology is a greek ward. It is derived from two ward mikes and logos mikes mean mesh room and logos mean study. Or The study of mesh room is called mycology . Myclogy deals life history of fungi,relationship of fungi and evolutionary tendencies of fungi. And The scientist who is concerned with fungi and structural ,reproduction ,physiology and taxonomy is called mycolgiest.
