Flashcards in Lecture 10-Fungi Deck (77)
Fungi are __________.
Fungi have cell walls made of __________.
Fungi are closely related to __________.
Flagellated single cell ancestors diverged how long ago?
__________ are absorptive heterotrophs.
Absorptive heterotrophs secrete __________.
Fungi exhibit many different lifestyles, such as:
Decomposers, parasitic, mutualistic
Fungi are _____ celled and __________.
An example of a single celled fungi is __________.
Yeasts reproduce via __________.
__________ digest food outside the body.
__________ is the biggest organism in the world.
Two categories of hyphae are:
Septate and Coenocytic
This category of hyphae are fungal cells separated by porous septum. Pores allow exchange of small molecules. (E.g. Ribosomes, mitochondria, nuclei).
This category of hyphae lacks septa and has continuous cytoplasmic mass.
Multicellular fungi that is a mass of hyphae. It's the main body of fungi and persists mostly underground.
Multicellular fungi that is specialized hyphae that form symbiosis with: host and exchanges or extracts nutrients.
A host with exchanges is a __________ relationship.
Type of relationship where one organism extracts nutrients from another.
Mutualistic haustoria associated with plant roots; improves water and nutrient uptake.
__________ facilitated plant movement on to land.
Parasitic haustoria associated with nematodes.
Fungi produce spores through __________ or __________ life cycles.
Sexual or asexual
In the __________ phase of fungal reproduction, haploid mycelium produces haploid spores, which may be contained in a sporangium.
Step 1 in the sexual phase of fungal reproduction: haploid mycelium produce __________.
__________ signal for potential partners.
Step 2 in the sexual phase of fungal reproduction: mycelia exhibit movement towards a __________ __________ of different 'mating types' (similar to different sexes).
