Biological Classification 2 Flashcards
Organism which move and capture their prey by putting out pseudopodia as in Amoeba
Amoeboid protozoan
A parasitic amoeboid protozoan
Entamoeba
Trypanosoma is an example of
Flagellated protozoan
Ciliated protozoan have a cavity that opens to the outside of the cell surface
Gullet
Paramoecium is an example of
Ciliated protozoan
Plasmodium is an example of
Sporozoan(protozoan)
White spots seen on mustard leaves are
Parasitic fungi
What causes wheat rust
Puccinia
A fungi that is a source of antibiotics
Penicillium
Unicellular fungi
Yeast
Long slender thread like structures in fungi
Hyphae
Network of hyphae is k/a
Mycelium
Continuous Hyphae tubes filled with multinucleated cytoplasm
Coenocytic hyphae
Cross wall structure present in hyphae of some fungi
Septae
Fungal cell wall is made of
Chitin and polysaccharides
Fungi are mostly
Saprophytic heterotrophs
Fungi that depend on living organisms
Parasitic
Examples of symbionts
- Those that live in association with lichens
- Those that live in association with mycorrhiza
Methods of reproduction in fungi
- Fragmentation
- Fission
- Budding
- Spore formation
Spores in fungi are called
Conidia /sporangiospores/ zoospores
Sexual reproduction in fungi is by
Oospores
Ascospores
Basidiospores
Fusion of protoplasms between two motile or non motile gametes
Plasmogamy
Fusion of two nuclei
Karyogamy
Meiosis in zygote resulting in
Haploid spores
When fungus reproduce sexually what comes together to fuse
Haploid hyphae
In ascomycetes and basidiomycetes, an intervening dikaryotic stage( two nuclei per cell). 1. The condition is:-
and2. The phase is:-
1.Dikaryon
2.Dikaryophase
Which fungi has aseptate and coenocytic mycelium
Phycomycetes
Asexual reproduction through zoospores (motile) or by aplanospores(non-motile) occurs in
Phycomycetes
In which fungi spores are endogenously produced in sporangium
Phycomycetes
Fusion of two gametes in fungi result in
Zygospore
Gametes similar in morphology
Isogametes
Gametes dissimilar in morphology
anisogamous/oogamous
Mucor is an example of
Phycomycetes
Rhizopus(the bread mould) is an example of
Phycomycetes
Albugo(parasitic fungi on mustard) is an example of
Phycomycetes
Sac fungi
Ascomycetes
A multicellular ascomycete
Penicillium
A unicellular ascomycete
Yeast(Saccharomyces)
Saprophytic fungi
Ascomycete
Decomposer fungi
Ascomycetes
Parasitic fungi
Ascomycetes
Coprophilus(which grow on dung) fungi
Ascomycetes
Which fungi has branched and septate mycelium
Ascomycetes
Basidiomycetes
Which mycelium produce asexual spores (conidia) exogenously on the special mycelium (conidiophores)
Ascomycetes
Sexual spores in ascomycetes
Ascospores
Ascospores produce endogenously in sac like structure called asci
Asci are arranged in fruiting bodies called
Ascocarps
Aspergillus is an example of
Ascomycetes
Claviceps is an example of
Ascomycetes
Neurospora is an example of
Ascomycetes
Morels is an example of
Ascomycetes
Truffles is an example of
Ascomycetes
In which fungi asexual spores are not found
Basidiomycetes
In which fungi vegetative reproduction by fragmentation takes place
Basidiomycetes
Sex organs are absent in
Basidiomycetes
In which fungi plasmogamy is brought by fusion of 2 vegetative or somatic cells of different strains
Basidiomycetes
The nature of resultant structure of plasmogamy in basidiomycetes is
Dikaryotic
The resultant structure of plasmogamy in basidiomycetes gives rise to
Basidium
Karyogamy and meiosis takes place in Basidium producing
4 basidiospores
Basidiospores are exogenously produced on
Basidium
Basidia are arranged in fruiting bodies
Basidiocarps
Agaricus(mushrooms) is an example of
Basidiomycetes
Ustillago(smut) is an example of
Basidiomycetes
Puccinia(rust) is an example of
Basidiomycetes
Bracket fungi or pufballs are examples of
Basidiomycetes
Imperfect fungi
Deuteromycetes
Alternaria is an example of
Deuteromycetes
Colletotrichum is an example of
Deuteromycetes
Trichoderma is an example of
Deuteromycetes
Deuteromycetes reproduction
They reproduce only by asexual spores k/a conidia
Deuteromycetes decomposers help in
Mineral cycling
