★ Must-know
Further detail
Oomycetes have fungal-like ecological roles and modes of heterotrophic nutrition. - Richards et al., 2006
Some oomycetes infect plants or animals.
More than 700 oomycete species are known, with aquatic and terrestrial representatives and saprophytic or pathogenic lifestyles.
Fungal-like lifestyle, but oomycetes are not fungi
1. An organism has a fungus-like lifestyle but is classified outside kingdom Fungi. Which group best fits this description?
2. A microscopic organism develops branching, tip-growing hyphae that form a mycelium and absorbs nutrients after releasing enzymes. Which description best matches these traits?
3. A cell wall analysis finds cellulose together with β-1,3 and β-1,6 glucans. Which organism group does this composition support identifying?
What are oomycetes, and to which kingdom do they belong?
They are stramenopilous water molds, not members of kingdom Fungi.
Which source is cited for oomycete hyphae and absorptive nutrition?
Beakes and Sekimoto, 2009.
What primarily composes oomycete cell walls?
Cellulose and β-1,3 and β-1,6 glucans.
What flagella do motile oomycete cells have?
Two heterokont flagella.
What is the ploidy of Oomycete somatic nuclei?
Diploid.
What resistant sexual spore forms as a diploid zygote after oosphere fertilization?
An oospore.
