Thank you miss

[@rennysabu3959]

unique style of teaching

[@themaskedguy07]

14:29 There's a simple reason to it. The flower need not be showy or produce nectar. And since it's a surer method and takes less time because of travel of pollen on the same flower. Hence this method is economical for the plant.

[@anaaaV3012]

c) they are easily carried by wind and are characteristic of wind pollinated plants. d) they swing hard on the contact of wind and help in pollen dispersal by wind due to their fragility e) it draws in nectar sucking insects and allows pollination by entomophily.

[@salonisingh153]

Self-pollination is more economical for plants as they do not have to develop large and attractive flowers,flagrance,necter etc.., and there is less wastage of pollen-grains in self-pollination .. Your explanation is very good

[@atharvjoshi7715]

Kya aap Indore me rhti hoo

[@krisharts7525]

WOW

[@anaaaV3012]

a) allows catching of dispersed pollen grains in the wind and increases the adhesiveness of the attachment. b) They are responsible for attaching insects and birds towards the flower and allow the dispersion of pollen by the mode of these insects and animals.

Advantages of the following parts in flower..... a) long and feathery stigma help to trap pollen grains in wind pollination b) attracting insects for cross -pollination c) easily carried by wind to enable cross pollination d)even slightest wind can move them e) attracting insects for pollination

[@vanshitadiwaker6884]

Happy Teacher's Day. You are the best.

[@artful_alchemy9]

1) long and feathery stigma can catch pollen grain easily of an anemophilous flower. 2) Brightly coloured petals attract insects which works as agents for cross pollination of an entomophilous flower 3) The pollen grain is smooth and light weight so the pollen grain can easily get stick to the stigma of an anemophilous flower 4) Protruding and easily movable anthers scatters pollen grains for pollination of anemophilous flower. 5) Fragrant nectar attract insects in entomophilous flower.

[@lakshyagaming23]

long answer type. 1) large anthers and stigmas hang outside the flower to catch the wind. 2) Petals are brightly colored to attract insects for pollination. 3) Anthers make large amounts of small, smooth, light pollen grains that float on the wind. 4)Protruding and easily movable anther helps in pollination of flowers by the wind. 5)Fragrant nectar helps to attract insects. please let me know if my answers are correct. I am your new student from DUBAI. Your teaching style is very interactive and funny! thank you for the videos. They are amazing.

Question: Self Pollination is more economical for the Plant . Why ? Answer : *This is because of the following reasons/conditions: - ▪︎ A lot of nutrient material is saved like pollen, nectar, scent and Large Petals. ▪︎ No × Wastage of pollen grains And lastly ▪︎ Good Character/ Parental characteristics are preserved.

[@tanyagawas6816]

* self pollination is more economical for the plant as all the good characters are preserved also there is no use for producing nectar or having scent and attractive/ bright petals as it is self pollination Q2) a)flowers have long and feathery stigma to trap the pollen grains b) flowers have brightly coloured petals to attract the insects for pollination C)Flowers have smooth and light pollen because they can be carried away easily by the wind d) flowers have protruding and easily movable anthers so that they are easily exposed to the winds e)Flowers have fragrant nectar fragrance is against for attracting the insects for pollination and nectar is the food for insects so when the insects come for food the pollen grains stick to them and thus pollination can be Carried out P.S. thank you so much miss I loved the video hope I have answered correctly 🤞🏻💕💕 *FIB- a) autogamy b) dichogamy

[@rameshv4645]

Miss you told that in self sterlity that pollen grain cannot mature at the stigma of the same flower.so miss how does the stigma of the flower come to know that the pollen grain is of same flower or diff flower.

there are chemical receptors beta on pollen and stigma

self pollination is more economical in plants because as the pollination takes place in the same flower or other flower of the same plant so, it need not to be showy nor it should contain nectar. And there is also not much wastage of pollen grains.

[@yogendrakumarpal1946]

Self pollination is more economical for the plant because in self pollination transfer of pollen grains from anther to stigma takes place on same flower as a result their is less wastage of pollen grains

[@zhenyunkewzshwa4788]

It's cute the way you teach!!! Understantable!!!!✨

[@nishtha9542]

Since self pollination does not require production of nectar, scent, large showy petals, it is able to save time and energy, thus being great for economy of plant.

[@maanyamaster7851]

14:25 Flowers who need to attract insects for pollination need to be large, bright, colourful, have a sweet scent, produce nectar and a large quantity of pollen grains. Self pollination is economical because a lot of energy and nutrients is saved by not having to do all this 22:25 a) autogamy b) dichogamy 32:35 a) anemophillous flowers as it has to catch pollen grain suspended in air b) entemophillous flowers as it has to attract insects c) anemophillous flowers so that the pollen grains do not stick to different surfaces while being pollinatdd by wind d) anemophillous flowers so that the wind can easily carry the pollen grains e) entemophillous flowers as it has to attract insect

[@shubhavigupte3292]

Self pollination is more economical for the plants as the pollen grains are not transmitted from one flower to another and there is less wastage of pollen grains also it do not need the flowers to be showy or to produce nectar or fragrance

[@drub4u]

bang on answer..

[@Palaktandon573]

The self pollination is economical because of thre following reasons 1)species are preserved from extinction 2)less watpstage of pollen grains 3)the flower need not be showy 4) the flower need not produce nectar 5)Pollination is much surer in self pollination in bisexual flower where both stamens and carpel are matured

It does not need to produce nectar 3. Wastage of pollen grains is prevented and therefore it does not need to produce pollen grains in large quantities

[@drub4u]

Very good beta..

[@kirtichaudhary9609]

14:33 because firstly it consumes less time and it is surer method.

Self pollination is more economical because it is a surer method where the good parental characteristics are preserved and minimal wastage of pollen grains takes place. Ma'am I saw the video today and here is the answer for the first question

Long answer type (a)The long and feathery stigma present in wind pollinated flowers(anemophilous flowers) help to trap the pollen grains easily. (b)Brightly colored petals in entomophilous flowers help them to attract insects for pollination. (c)The smooth and light pollen grains in anemophilous flowers help them to be easily carried away by wind without being stuck on surfaces. (d)The protruding and easily movable anthers in anemophilous flowers help their pollen grains to easily get detached from them and get carried by wind. (e)The fragrant nectar present in entomophilous flowers attract insects for gathering nectar which in turn carry the pollen grains with them.Hence, helping in pollination. -Jahnvi Singh 😇
