Basis of 5 kingdom of classification
cell structure, body organisation, mode of nutrition, mode of reproduction, phylogenetic relationship
they play imp role in recycling nutrients
chemosynthetic bacteria
citrus canker is caused by
bacteria
golden algae aka
desmids
under suitable condition slime moulds produce?
plasmodium( several feet long)
under unfavourable condition slime moulds produce

special feature of aquatic amoeboid protozoans
having silica shell on their surface
example of amoeboid protozoans

budding, fragmentation, fission
asexual spores in fungi
conidia, sporangiospore, zoospore
sexual spores in fungi
oospore, ascospore, basiospore
stages of sexual steps in fungi
plasmogamy→karyogamy→meiosis
dikaryon condition or dikaryophase is seen in
ascomycetes and basidiomycetes
basis of classification of fungi into different classes
morphology of mycelium, mode of spore formation,fruiting bodies
phycomycetes has
aseptate and coenocytic
asexual reproduction in phycomycetes is by
zoospores or aplanospores
motile asexual spores of phycomycetes
zoospores
non motile asexual spores of phycomycetes
aplanospores
asexual spores of phycomycetes are produced
endogenous produced in sporangium
example of phycomycetes
mucor, rhizopus, albugo
parasitic fungi on mustard
albugo
coprophilous fungi
ascomyctes
asexual repro in ascomyctes
conidia
asexual spores formed on conidiophores are exo/endo
exogenous
ascomyctes aka
sac fungi
sexual spores of ascomyctes are
ascospores
ascocarps bear spores exo/endo
endogenous
examples of ascomyctes
neurospora, aspergillus, clavicep
edible asco
morels and truffles
asco used in biochemical and genetic work
neurospora
class of fungi which lives as parasite on plant
basisio
2 unique feature abt basidio
asexual repro abs
sexual repro +nt but sex organs ab
karyogamy and meiosis in basidio occurs within?
basidiocarp
basidiocarp bears sexual spores exo/ endo
exogenous
example of basidio
agaricus, ustilago(smut), puccinia(rust fungus)
deuteromyctes reproduce only by
conidia
mineral recycling fungus
