Thank you sir 🙏
Herkogamy: mechanical barrier.
Clestigamy: close flower
Ophiophily: pollinated by snake
Wind pollinated adaptation: light pollen grains,one ovule in each ovary,well exposed stamen stigma,feathery stigma,
47:57 highcort may case on talegram by dr geetrandra singh
Plz 🙏🙏🙏🙏🙏 repley anyone
How much syllabus of bio chem and physics
Has been completed till now
For neet 2021 in regular and focus batch
1-herkogamy= morphlogical barriers in flower to avoid self pollination
2-Cleistogamy = flowers remains closed after maturation to promote 100%self fertillization
3-Entamophily = polination by means of insect
4-ophiophily =pollination by means of snakes
5-pollination by means of Bat = chiroptarophily
6-adoptations are as follows
anther produces huge amount of pollen grains
stigma become large and feathery
pollen grains light weighted and have wings like structures to assure a drastic flight
hope i did it correctly
5- chriptophyli
6- feathery segment
1-mechanical barrier
2- closed flower chriptophyli
herkogamy=
cleistogamy: the flowers of some plants remain close so as to promote self pollination
entomopjily: pollination by insects
ophiophily: pollination by snakes
pollination by bat: chiropterophily
adaptation of wind pollinated flower:
1. stigma will be feathery and long
2. pollen will be light weight
3. no nectar will be produced by the flower and also not are very brightly coloured
4. anther will be protruding
the adaptation shown is of wind pollinated flower
Herkogamy -barrier between male and female flower
Cleistogamy -close flower
Entomophily -through insect pollination
Ophiophilly- through snake pollination
Through Bat pollination -chireptophilly
Wind pollination flower-stigma -feathery
Anther -small , wingy ,light
Sir human physiology ke lectures Video aapne delete q kiye sir… 😔
Good evening sir
1-. Flower have Barrier bw androceium nd gynoceium
2-. Pollination by incsect
3-. Pollination by snake
4-. Chirepterophily
5-. Long and feathery stigma , sticky and large poolen grain
6-. Wind pollination
7-.
5:57-wind pollination
Herkogamy-marphological barrier due to which self pollination not possible
Cleistogamy-closed flower,self pollination,bisexual
Entamophily- insect pollination
Ophiophily- snake pollination
pollination by bat – Chiropterophily
Adaptation for wind pollinated flower- stigma- long ,adhesive,hairy & long style ,light pollen grains
Fig.wind pollination
Herkogamy – physiological barrier
Cleistogamy – flower which do not open at all
Entomophily – pollination by insect
Ophiophily – pollination by snake
Pollination by bat – chiropterogamy
Adaptation in a wind pollinated flower
⚪style is well exposed in air
⚪pollen grains are light , nonsticky
⚪stigma is long feathery and hairy
Wind pollinated flower
herkogamy-some morphological bariers to prevent self pollination
cleistogy- closing of flowers to ensure self pollination
entomophily- pollination by insects 👏🐛🐜🐝🐞
ophiophily- pollination by snake 🐍 🐍 🐍
pollination by bat ⚾⚾-
adoption in wind pollination -🎑💨🍃🎐
staments are long and we'll exposed ones
stigma is stikky and long
polengrain💣 are released in larger number light and nonstickky
flower are colourless and no nector is present
👁️🗨️ HERKOGAMY – Morphological barrier and ensure No self pollination to promote outbreeding.
👁️🗨️Cleistogamy – The closed flower ( promote self pollination) eg. Viola, oxalis and commelina
👁️🗨️ Entemophilly – pollination by insects.
👁️🗨️ Ophiophily – Pollination by Snake 🐍
👁️🗨️ Chireptophilly – Pollination by Bats.
👁️🗨️ Adaptation in wind pollinated flowers-
1. Dull flower
2. No nector
3. Thousands of pollen grain
Produced.
4. Stigma lie above than other florals
Parts.
5. Feathery stigma .. eg. Corn 🌽
👁️🗨️ Given fig. Is Wind pollinated flower. eg. Grass family
7=it is adoptation of wind pollination
1= Herkogamy=IN this a barrier is establish to prevent self fetilization of the flowe
2.clestogamy=in this the floer is closed which ensured that self fertlization of same flower
3.entomophilly=it is the pollination carried out by the insects
4.ophiophyly=pollination of snake
5=chirophyly pollination by bats
6=in wind pollination=the pollens are light weith,nonsticky,flying etc.stigma is large and feathery
Herkogamy ❤️Morphological barrier which prevents self pollination
Cliestogamous ❤️ closed flower
Entamophily ❤️ pollination by insect
6:00Pollination-Wind pollination
Cliestogamy -closed flower
1)Herkogamy-some morphological barrier which make self pollination impossible, flower mature at different time
2)cleistogamy-pollination in closed flower(self pollination)
3)Entomophily-pollination by insects
4)Ophiophily-pollination by snakes
5)🙄🙄🙄
6) Adaptation in wind pollinated flower-a) pollen grains are light in weight
b)stigma should be long and sticky
c) pollen grains should be released in large numbers
Ophiophily pollination by snake
Chiropterophily pollination by bats
Entamophily pollination by insect
Herkogamy ?
Dichogamy ?
Myrmacophily ?..
Cleistogamous closed flower
Herchogamy mechanical barrier
41:30 YOU CAN WIN
Herkogamy- morphological barrier resists pollination
Cliestogamy – flower do not open at all and assured self pollination and seed set occurs
Entomophily- pollination by insects
Ophinophyiy- pollination by snake
Chiropterophily- pollination by bat
Wind pollinated flower has well exposed stamens and large often feathery stigma. Non sticky pollen,have no nectar and are not colour full
Sir you said that fig and fig wasp not survive without each other if any one of them disappear but when we are studying evolution there you said that ki jeevan apni rah khud dhod leta hai to kya ye inme naho hoga??
To kya sir ye apne liye reproduction ka tareka dusara nahi choose karenge
Hercogamy – morphological barrier
Cleistogamy – same plant but different flower
Antomophily -insect pollination
Herkogamy- maturation of flower at different time.
Cleistogamy -no mature of flower at time of fertilization.
Ophiophily-snake
Pollination by Bat-chieropteriphily
Wind pollinated flower – feathery and light weight -stgma and pollen grain.
Adaptation for wind pollination
Herkogamy: when morphological barrier is developed to prevent self fertilization…
Cleistogamy: when flower is closed to promote self fertilization
Pollination by bat : chaeroptophilly
Pollination by snake: ophiopholly
Wind pollination adaptation
1 feathery stigma
2 pollen grain produce in enormous amount
Pollen should be light weight
Thankyou sir 🙏
Herkogamy-Morphological barriers makes self pollination impossible
Thanks 😊 sir
For this fantastic lecture 🙌
Thankyou sirji 🙏💓
Wind pollination
1 ) morphological barrier between male and female part
2 ) closed flower
3 ) pollination by insect
4 ) pollination by snake
5 )……….
6 ) wind pollination adaptation
Feathery stigma, pollen relased in huge no. , flower nector less odourless non attractive flower
5:50 – wind pollination
Q1) Herkogamy :- in some flowers morphological Barriers developed in which make self pollination impossible
Q2)Cleistogamous flowers :- in this type of flower were we have see pollination is closed type so the anthers and stigma lies close to each other . They fully promote self pollination
Q3) Entomiphily :- Pollination by insects
Q4) ophiophily :- Pollination by 🐍
(SNAKES)
Q5) Bat :- chiropteriphily
Q6) adaptation of wind pollination :-
1) pollen grains are light and non sticky
2) when exposed stamens
3) pollen grains are feathers in structure so they stick on the surface of stigma
4) No need of external Pollinating agens
Q7) 5:41 :- Wind pollination
Thank you so much for your efforts sir ❤️
Thank you commander 💞
