(26 cards)
What’s the function of Spitzenkörpers?
Deliver vesicles containing cell wall building materials in hyphae growth
Why are septa formed?
Delimit reproductive structures
Seal off injured parts
What are the two main types of septal pores?
Simple pore
Dolipore
What are the functions of septa?
Strengthening rings
Blocking off injured parts
Restricting cytoplasmic continuity, allowing differentiation
What is the function of clamps?
Ensures each compartment is dikaryonic (one nucleus from each parent)
What are the different hyphae types in fruit bodies?
Generative
Skeletal
Binding
What are monomitic fruit bodies?
Only generative hyphae type
What are dimitic fruit bodies?
Have Generative and skeletal hyphae types
What are trimitic fruit bodies?
Have all three hyphae types
What are the snares of predatory fungi?
Constricting rings
Adhesive rings
Adhesive knobs
Adhesive spores
Hooked conidia
What structure breaks into plant cell walls?
Appressorium
What structure enters the plant cell?
Haustorium
What’re the functions of arbuscules and pelotons?
Arbuscules - branched structures in root cells for nutrient exchange
Pelotons - temporary structures which release nutrients in those cells
Function of rhizoids?
Anchorage
what is prosenchyma
loosely woven hyphae
what is pseudoparenchyma
thin walled, short cells rounded by mutual pressure formed of hyphae
what is pseudosclerenchyma
dark, rounded and thick walled plectenchyma tissue
what are the Plectenchyma Tissues?
any tissue organized from hyphae
* prosenchyma
* pseudoparenchyma
* pseudosclerenchyma
what might sclerotia give rise to?
mycelium
external fruiting structure
internal fruiting structure
what is plasmogamy?
Joining of thalli
what is karyogamy?
joining of nuclei
What spores do ascomycota have?
Ascospores in ascus
What spores do mucoromycotina?
Zygospores with suspensors
