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.
What else can I help you with?
What is pollens features?
Pollens are small, powdery grains produced by seed plants that contain the male reproductive cells. They are typically dispersed by wind, water, or insects to fertilize female plants of the same species, leading to the production of seeds. Pollen can trigger allergies in some individuals when inhaled.
Does Grain produce nectar?
No, grains do not produce nectar. Nectar is usually produced by flowering plants to attract pollinators like bees and butterflies. Grains, such as wheat, rice, and barley, primarily produce starchy seeds that are used as a food source.
What kind of spores are produced by flowering plants?
Flowering plants produce pollen grains, which are equivalent to spores in non-flowering plants. These pollen grains are responsible for plant reproduction through the process of pollination, where they are transferred to the female reproductive organs of the flower for fertilization.
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.
Anthers produce special cells called what?
Anthers produce special cells called pollen grains. These pollen grains contain male gametes, which are essential for the process of fertilization in flowering plants. During pollination, pollen grains are transferred to the stigma of a flower, where they can germinate and form a pollen tube to reach the ovule.
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 are grains that produce sperm cells called?
Microspore mother cell after undergoing meiosis produces pollen grains, and the pollen grains during germination produce sperms by undergoing pollen mitosis.
What kind of spores are produced by flowering plants?
Flowering plants produce pollen grains, which are equivalent to spores in non-flowering plants. These pollen grains are responsible for plant reproduction through the process of pollination, where they are transferred to the female reproductive organs of the flower for fertilization.
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.
Can you get hayfever from sun?
No. Only from the pollens given off by many types of plants.
What is the scientific name for pollen grains?
The scientific name for pollen grains is "microgametophytes." These are the male gametophytes in seed plants that produce the male gametes necessary for fertilization.
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.
What parts of flowering plants are responsible for gamete production?
Anthers produce the pollen grains; ovary produces the ovules
