Fungi Video Lecture | Science & Technology for UPSC CSE

common mushrooms
toadstools and the mold on leftover
bread are all examples of fungi fungi
can be found everywhere
water
[Music]
soyal
plans and animals
well there are some fungi like Virginia
that can cause diseases like we trust in
plants
unlike Penicillium that provide us with
antibiotics
with the exception of yeasts
char unicellular
fungi are usually filamentous
fungi consist of long
lender thread-like structures called
hyphae
work of hyphae is known as mycelium
there are two types of highway
first type is made up of continuous
tubes filled with multinucleated
cytoplasm and is called C no psychic
highway
the second type of highway has safety or
cross walls
from hyphy
wish'd by their cell walls
made of chitin and polysaccharides
fungi are heterotrophs
[Music]
bonzai that absorb organic matter from
dead substrates are called sepra fights
fungi which depend on living plants and
animals are called parasites
some fungi are associated with other
organisms in mutually beneficial
relationships
Shampoo
sanjaya associate with algae to form
lichens
roots of plants as mycorrhizae
in both lichens and micro riser
the relationship share
enjoy with the algae and the plant miss
called symbiosis
fungi can reproduce vegetatively
sexually
reproduce vegetatively by fragmentation
vision
and budding
they can reproduce asexually by either
one of the following spawns
Lydia
Zuse boys
sporangia spawns
they also reproduce sexually by either
moose paws
boys or the sidious boys
all these spores are produced in
structures called fruiting bodies
there are three steps in the sexual
cycle
Mogami
Carrie Agha me
meiosis
the first stage involves the
Auto Klassen's between two more tile or
non motile gametes
called plasma gimme
as Mogami occurs when two haploid hyphae
of compatible mating types fuse
Mogami
the two nuclei fuse together in the
second stage known as Arriaga me
some fungi the fusion of two haploid
cells immediately results in the
formation of diploid cells or 2n
the fungi
like
to my seats
and intervening dikaryotic stage occurs
this condition of two nuclei per cell is
called die carrion
is called dye carrier phase
later the parental nuclei fuse to make a
diploid cell
the third stage involves reduction
division
that is meiosis
perform at Lloyds paws
meiosis occurs in the fruiting bodies of
fungi
the fruiting bodies
the motive spore form
of the mycelium form the basis of the
division of the kingdom fungi into
various classes
four main classes of bonsai
like oh my seats
ascomycetes
the city of my seats
and deutero my seats
like oh my seeds are found in a
habitats
in moist places
sites on plans
Yuuka
rhizopus
and alb you go
samples of FICO my seeds
it's have a septate and sinusite ik
mycelium
sexually by Zeus pause in the case of
motile gametes
and by a planners pause in the case of
non motile gametes
on the other hand
sexual reproduction leads to the
formation of Zygo spores after the
fusion of gametes
the gametes may be either similar or
dissimilar
members of the ascomycetes class are
commonly known as sack fungi
[Music]
Aspergillus
GLaDOS Epps
and Neurospora
they can be unicellular like yeast or
multicellular like Penicillium
saprophytic
decomposers
parasitic
Oh kapre Phyllis
that is they go on dung
ascomycetes have branched
and septate mycelium
reproduce asexually by spores called
Canadia that are produced exogenously on
the special mycelium called Canadia
falls
sexually they reproduce through spores
called ascospores that are produced
endogenously insect like a sky
a sky in turn
Tooting bodies called ASCO cups
members of ascomycetes
rales
[Music]
edible
others like Neurospora are used in
biochemical studies
some common examples of basidiomycetes
are mushrooms
bracket fungi and puff balls they grow
in soil
blogs and
inside plant bodies as parasites such as
rust and
ascomycetes
the Cydia my seats to have branched and
septate mycelium
production by fragmentation is a common
form of reproduction among
basidiomycetes
sexual reproduction
in basidiomycetes takes place even in
the absence of sex organs
in the plasma Gumi stage
genotypes fuse to form a die carry out
the dikaryotic mycelium gives rise to
the fruiting body called the Basilica
arise and produce the city of spores
exogenously as a result of meiosis
the last class of fungi Deuter of my
seats is known as imperfect fungi
because we do not know enough about
their life cycles only their asexual or
vegetative phases are known due to my
seeds reproduce only through asexual
spores known as Canadia
they too have a septate and branched
mycelium
Seppo fights or parasites when a large
number of them are decomposers
helped in mineral cycling
Lewton area
let her try come
and Trichoderma are examples of deutero
my seats
therefore
members of kingdom fungi display a
diverse set of characteristics
