Pathology L4.1 Fungi Flashcards
(29 cards)
How do fungi take up nutrients
By osmotrophy (digest externally than absorb directly through cell wall)
Mycelium
Body of filamentous fungus
Hyphae
Root like structure of mycelium that is composed of microscopic, branching, tubular cells
Appressorium
Specialized structure of fungus that help attachment during infection
Haustoria
A root like structure that forms when a specialized fungal hyphae penetrates a plant cell wall and expands inside the cell
How can fungi reproduce
Asexually by budding, mycelial separation, and fungal spores
Spores
A dispersal unit that consists of 1 or several cells capable of forming new hyphea and do not contain an embryo
Fruiting body
Complex fungal structures that contain or bear spores
Types of fruiting bodies
Perithecium (sexual)
