There are a lot of adaptations, and they are different depending on how the plant is pollinated. For example in wind pollinate species, the anthers hang out of the flower so they can get dispersed by the wind, the pollen is usually smooth or has air sacs and the stigma is feathery to increase the surface area and also hangs out of the flower.
In animal pollinated species, the anthers are usually prominently displayed so the pollinator can find them, the pollen is spiky so it can attach to the pollinator and the stigma is located somewhere the pollinators can get to it and is sticky. These are just generalizations and there are many variations on this theme.

What the function of the 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.
Male gametophytes of flowering plants?
Pollen Grains
What is the function of pollen cells?
It is the sperm of plants.The pollen cells goes to the female reproductive part of the plants through the wind,insects etc. It goes inside makes seeds the seeds mature they make new plants.
Which reproductive structures are produced within the ovaries of plants?
pollen grains

What is pollen grain like from non flowering plants?
Pollen grains from plants which do not flower are very similar to that of flowering plants, except they are different.

Why are no chloroplasts present in these pollen grains?
In most angiosperms (flowering plants), chloroplasts are maternally-inherited. Pollen grains (male seed) do not contain chloroplasts.
Which reproductive structures are produced within the ovaries of plants?
pollen grains
what are one of the main reproductive organs of plants?
pollen grains and ovules
What is the function of the pollen sacs in a flower?
the function of the pollen sac is to produce pollen (pollen grains). The pollen sac is the microsporangium of a seed plant in which pollen is produced. Most plants except coniferous plants contain four (4) pollen sacs.
