Fungal cell biology Flashcards
What are fungi made of?
Fungal hyphae - elongated strands and get together to form this structure
Describe yeast cells
Unicellular and rounded
Describe hyphae cells
Multicellular and elongated
What is isotrophic growth
Movement forward with the creation of membrane
What is polarised growth?
Elongation of the cell
Cytoskeleton
Supports transport towards the bud or hyphal tip
What is another form of fungi?
pseudohypha
What happens to the hyphal tip?
Cell wall forming enzymes travels there by fungal motors
What are the cytoskeleton of yeast cells?
Actin - myosin molecular motors
What are the cytoskeleton of hyphal cells?
Actin and microtubules, kinesis and dynein
Fungal spitzenkorper
Hyphal growth involves an apical body
Accumuclation of vesicles at the time - secretory and endocytic vesicles
What determines hyphal growth?
Rate of vesicle release and motility of spitzenkorper
Woronin bodies
Fungal based organelle
peroxisomes loses septa upon damage of fungal cell
Plus filamentous ascomycetes by self seemly of the protein Hex1
Whats the issue of multicellularity?
if one cell dies all of them die
How do damaged hyphal cells get isolated?
By a plug and by woronin bodies, concentrated around d a septal pore
