Pollen is the male contribution to the seed. Many plants have evolved flowers to lure pollinators, e.g. bees or flies, to carry packages of pollen to the female parts of another plant of the same species to fertilize it and thus produce a seed and continue the genetic lineage. The plants that do not rely on attracting pollinators tend to rely on the wind to spread their male genetic code around, and the wind is a very haphazard messenger. The plant is more likely to be successful - for a pollen grain to land on the proper part of the proper species of plant - if the producer makes LOTS of pollen. Plus, pollen/sperm is relatively cheap from the plant's point of view. A useful analogy might be to imagine two people stuck on little islands wanting to send letters back and forth. Pollinators are like mailmen that travel back and forth... so you only need to write your letter once. Relying on the wind to carry pollen is like writing 500 letters, stuffing them into 500 bottles and tossing them into the waves with the hope that one might hit the right island by chance.

Why doesva flower have so many pollen grains than 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.
Grains that surround and protect a plants sperm?
Pollen grains
Do pollination take place in ferns?
Yes they do. Most commonly called spoaring. They spread spoares in the air.
What do male cones produce?
Male cones produce many pollen grains to enhance its reproductive rate & hence its evolutionary success
How do Kiwi plants reproduce?
Kiwi plants are both male and female. They are able to reproduce because the male will produce useful pollen grains and the female will be able to receive the pollen for close to nine days while it is open.
Wind-pollinated flowers produce a lot of pollen grains?
To generate more plants by wind pollination in which some percentage of pollens succeed.
What plants that produce its own food?
all fruits and grains are food to plants also
What two things can vasular plants do that non-vascular plants cannot do?
vascular plants can produce pollen grains and seeds
Do bigger plants produce bigger seeds?
Usually, bigger plants do produce bigger seeds.
What are characteristics of seed plants?
Seed plants are characterized by the presence of ovules and pollen grains and after pollination and fertilization produce seeds from their ovules.
Why doesva flower have so many pollen grains than 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.
Can you get hayfever from sun?
No. Only from the pollens given off by many types of plants.
Are grains producers?
Yes. Grains are producers. Grains are plants and all plants are producers.
What parts of flowering plants are responsible for gamete production?
Anthers produce the pollen grains; ovary produces the ovules
What is this process called in which both plants and animals produce young?
In animals and in plants it is usually called sexual reproduction. Plants sometimes produce asexually.
Name two ways that plants ensure that their pollen grains have a greater chance of reaching the female part of their flowers?
they produce a tiny tube that the pollen grains travel to the egg cell.
Are grains vegetables?
No. Grains are seeds. They come from plants, some plants being vegetable.
