Lever mechanism for pollination is the characteristic feature of

Answer 1

Hi mate.


Thanks for asking this question.


Here is your answer,



$lever \: mechanism \: =$


In Salvia, flower is

bisexual and protandrous.

The two stamens of flower

have long bifurcated

( divaricate) connective.

Upper branch of

connective bears fertile

anther lobe while the

lower has sterile anther

lobe. An insects when

enters in the flower, it

pushes the lower sterile

lobe as a result the upper

fertile anther lobe bends

down.

It comes in contact

with back side of insects

body and pollen grains are

dusted there.


The same insect when

visits another flower with

matured gynoecium, the

pollen grains are picked

up by receptive stigma.

Such mechanism is called

Lever - mechanism of the

pollination.




Thank you.
