Which of the following is correct about class Deuteromycetes?
1. Some members are saprophytes or parasites.
2. A large number of members are decomposers of litter and help in mineral cycling.
3. Alternaria, Colletotrichum and Trichoderma are deuteromycetes.
4. All
Find the odd one with respect to the fungi imperfecti
1. Alternaria
2. Colletotrichum
3. Trichoderma
4. Penicillium
The imperfect fungi which are decomposers of litter and help in mineral cycling belong to
(1) Deuteromycetes
(2) Basidiomycetes
(3) Phycomycetes
(4) Ascomycetes
Deuteromycetes are known as ‘imperfect fungi’ because –
a. Only the sexual phases of these fungi are known.
b. Because they do not have true cell wall
c. Only the asexual or vegetative phases of these fungi are known.
d. They do not show typical fungal characteristics.
An artificial group within fungi is
1. Ascomycetes
2. Deuteromycetes
3. Basidiomycetes
4. Phycomycetes
Fungi imperfecti constitute a group that
(1) are obligatory parasites
(2) reproduce only asexually
(3) do not cause disease in humans
(4) resemble bacteria in some respects
The imperfect fungi such as Trichoderma
1. Reproduce sexually by spore formation
2. Have aseptate mycelium
3. Reproduce asexually by conidia formation
4. Have coenocytic mycelium

a. Zoospore
b. Aplanospore
c. Conidia
d. Oospore
