Why do pollen grains have air-sacs?
These air sacs make it easier to be carried by the wind
How does the pollen grains tube reach the ovary?
it is either get blown by the wind to another flower or carried by an insect.
Microspores mature into what?
Pollen Grains
What is the defference between self and cross pollination?
Self pollinationWhen pollen grains from a flower are carried to the stigma of the same flower or on the other flower of the same plant, the phenomenon is called self pollination.Cross pollinationWhen the pollen grains from a flower are carried to the stigma of the flower on other plant, the phenomenon is called cross pollination.

When pollen grains are carried to the female part of the plant what will happen to that part?
Pollination and hereafter, fertilization
What is the function of pollen grains?
Matured pollen grains contained sperm cells. When Pollen grains are sticky, you have pollen. Pollen grains are contained in the pollen sac, with the purpose of helping plants reproduce.

How does the pollen reach the stigma?
some pollen grains reach to stigma by wind and some are carried by animals like rabbits and insects like butterfly, bee etc.
How does wind pollinate?
On maturity of pollen grains , the anther lobes burst open and the pollen grains released in large amonut are carried by wind to several meters away to settle on feathery stigma as in case of plants of grass family.
