flowers produce more pollen grains because the anther makes the pollen it then the stigma collects pollen and the petals of flowers atract insects or birds.
Plants generally produce very large numbers of pollen grains because pollen is made as a plants way of reproducing, the pollen from one plant must mix with the flower of another in order to bear fruit or seeds. Since plants and trees are spread over vast areas, huge quantities of pollen must be released to be sure that it reaches another plant of its kind and as many of them as possible.
Flowers produce a large number of pollen grains because they are lost in transit while trying to fertilize one ovule. Microspore mother cells produce microspores that develop into pollen grains.
There are more pollen grains because they grow at a quicker pace.
Because the pollen grains have to travel by pollinating agents from anther to the stigma. To ensure their probability to achieve the task they outnumber the ovules.
flowers produce more pollen grains because the anther makes the pollen it then the stigma collects pollen and the petals of flowers atract insects or birds.
Pollen is easier to make Pollen travels so it is evolutionaryly beneficial to make more of the gammetes that have to "go out" in the real world where they can land on a non-receptive plant.
They produce poll grains in order to reproduce. Having thousands of pollen grains released increases the change that some of them will be able to fertilize an egg.
The pollens make the egg cells.
A flower's sperm is contained within the pollen grains. These pollen grains are produced in the male reproductive organs of the flower, called the stamens. When the pollen grains are transferred to the female reproductive organs of another flower, they can fertilize the ovules and lead to seed development.

When pollen grains land on the stigma(funny stick thingo on a flower), it wil start to grow a pollen tube, towards the ovary and the ovules. Then it GOES THROUGH the tube and =============*FERTILISATION*=====================
pollen grains are produced in pollen sac of anthers which are present on the male gamets of flower
The female part of (angiosperm) flowers inlcudes: the stigma, style, ovary and ovules. The male part of the flower inlcludes: the filaments, anther and pollen grains.

pollen grain
The ovules of the flower are produced in the ovary. The ovary is located in a region known as the gynoecium.
pollen grains and ovules
pollen grains are little grains in side a flower
Pollen, ovules and seed
it contains the ovules waiting to be fertilized by pollen

a flower produce pollen sacs which has pollen grains in it
Yes,Because pollen is the butterflies food.
