Answers:
1.)
Solution: d) Plasmogamy
In the protoplasm, the fusion between two motile or non-motile gametes is a Plasmogamy.
2.)
Solution: b) Fungi body is filamentous and consist of long slender thread like structure called as Hyphae. It absorbs nutrients from the environment.
3.)
Solution: c) Two
The zoospores are produced in sporangium. The formation of zygospore takes place by fusion of two gametes. Gamete that take part in the formation of zygospore are morphologically similar or dissimilar.
4.)
Solution: b) Meiosis which is a reductional division results in the formation of haploid spores as meiosis divides the chromosomes into half.
5.)
Solution: a) Deuteromycetes
Fungi include asexual or vegetative phases that are known in the Deuteromycetes, Hence, members of Deuteromycetes is known as imperfect fungi.
6.)
Solution:a) Algae and fungus, where algae prepares food by photosynthesis and fungus provides shelter and protection.
7.)
Solution: c) Ustilage
The members of Basidiomycetes includes examples such as puccinia, Agaricus and Ustilage. Other three remaining options are example of Deuteromycetes.
8.)
Solution: a) Isogamous is the term used when two morphologically similar gametes fusion results in the formation of a zygospore.
9.)
Solution: b) Conidia
In the members of Ascomycetes, asexually produced spores are called as Conidia. And sexually produced spores are called as Ascospores.
10.)
Solution: b) growing on dung, coprophilous are those saprobic fungi that are found growing in animal dung.
11.)
Solution: a) Albugo
Albugo is a parasitic fungi. On the other hand, Agaricus is mushroom and Rhizopus is the bread mould.
12.)
Solution: b) Conidia is asexual non motile spore of fungus which is sometimes also called as chlamydospore.
13.)
Solution: c) Basidiomycetes- rust fungi and ascus
All the given pairs except Basidiomycetes- rust fungi and ascus are correct pairs. Basidiomycetes- rust fungi and ascus is an incorrect pair because Basidiomycetes does not include ascus.
14.)
Solution: a) Neurospora is used as genetic material because it life cycle is short and is easy to grow. Also dominant and recessive characters are easily expressed in it.
15.)
Solution: a) Basidiocarps
On the basidium, basidospores are exogenously produced. Hence, arranged basidia in the fruiting bodies are called as Basidiocarps.
16.)
Solution: b) Deuteromycetes is called as imperfect fungi because sexual reproduction is absent in these particular fungi group.
17.)
Solution: b) Non-motile
In the phycomycetes, asexual reproduction occurs by zoospores and they are motile. Hence, asexual reproduction occurs by aplanospores and aplanospores are non-motile in the phycomycetes.
18.)
Solution: a) Septate and branched, septate because septa divides hyphae into uninucleated or multinucleated cells. Whereas branched because cluster of hyphae is separated by a septa.
19.)
Solution: a) In the different types of fruiting bodies, arranged asci are known as Ascocarps.
Arranged asci in the different types of fruiting body are known as Ascocarps. Hence, statement ‘a)’ is correct one.
20.)
Solution: a) Rust, puccinia is called as rust fungus because it causes wheat stem rust disease and it is a macrocyclic fungus.
21.)
Solution: b) Fungi
The common mushrooms and toadstools are included in the kingdom fungi. Hence, the common mushrooms and toadstools that we eat are actually fungi.
22.)
Solution: a) PeniciMum produces antibiotics to inhibit the growth of bacteria and thus reduces the competition in the environment.
23.)
Solution: b) Penicillium
Fungi show great diversity in morphology and functions. Some fungi can cause disease, some fungi cause wheat rust and some are sources of antibiotics. Among all fungi, Penicillium is the source of antibiotics.
24.)
Solution:a) Rhizopus causes bread mould because spore of it falls on the bread and starts to multiply due to it starts a colony and a mould appears.
25.)
Solution: a) Yeast
Kingdom fungi mostly include multicellular organisms. Yeasts are useful in the beers and breads. Yeast is a unicellular fungi. Hence, it is an example of unicellular fungi.
26.)
Solution: d) All are correct because reproduction in fungi can also occur through vegetative means which includes fragmentation, fission and budding.
27.)
Solution: d) Chitin
In the members of fungi, cell is generally thin. Cell wall which is made up chitin helps cell in structural support and adds rigidity. Hence, cell wall of fungi is made of chitin.
28.)
Solution: a) Yeast helps in making bread by producing carbon dioxide during year’s respiration and that gas trapped in dough causing it to rise. Whereas in beer carbon dioxide and ethanol are produced by yeast during fermentation.
29.)
Solution: c) Organisms of fungi can produce both asexual spores and sexual spores.
The organisms of fungi produce mitospores by asexual cycle and produce meiospores by sexual cycle. Hence, they can produce both asexual and sexual spores.
30.)
Solution: a) Mycelium. When many hyphae grow they come near to each other and then fuse to form a new structure called as mycelium.
31.)
Solution: a) Both ii) and iii) are incorrect pairs
In the asexual reproduction, mycelium produces spores. In the fragmentation, a part of mycelium becomes separated. Hence, Both ii) and iii) are incorrect pairs.
32.)
Solution: b) Parasites
Saprobe type of fungi are decomposers and mutualist’s type of fungi include two organisms where both get benefited. Hence, parasitic type of fungi can harm host like rust and smuts (Attach plants).
