More than one, the number depends on the mode of pollenation.

How many pollen grains are deposited into the female flower?
as many that stick to the stamen. it differs from plant to plant and it also depends on how many pollen grains stick to the insect that carries it. though once the pollen grain comes into contact with the stamen a pollen tube is created to reach the ovary. then two "sperm" come from this tube and one fertalizes the egg and one become the endosperm for nutrients for the egg/seed
How does pollen help a plant?
Pollen helps plants to fruit. -For instance without pollination we would have very few Almonds, blueberries, strawberries, melons, cucumbers, tomatoes and many others. Pollination of plants is critical to human survival.
HOW DO YOU use pollen in a sentence?
There are many diffrent ways to use pollen in a sentence, but here is an example of one: The flower includes pollen, which insects, such as bees, use to stey alive.
How can pollen be transfered from plant to plant?
POLLEN GRAINS ARE TRANSFERRED BY 3 METHODS: 1. BY WIND 2. BY INSECTS 3. BY WATER. it depends on the type of plant. some plants can be insect pollinated and some wind and some that are located near a river by water
Why do plants produce nectar?
plants have nectar to reproduce. When the insect or bird lands on the plant nectar gets stuck to it. The animal then goes to another plant and spreads the nectar. Then a new plant ts produced. actually, nectar is a sweet liquid produced to attract pollinators (for this example lets say bees, though there are many). The pollen (flower sperm) gets attached to the bees and when they land on another flower, the pollen goes into the stigma (female part of a flower) to produce a seed.
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 are the inside parts of a flower?
It contains stigma, style, ovary, ovul, anther, filament, pollen grains, pollen tube , sepal, petals, and many more in a flower.
What do male cones produce?
Male cones produce many pollen grains to enhance its reproductive rate & hence its evolutionary success
A conifer that has both male and female cones will produce many more pollen grains than ovules How does that help the conifer reproduce?
The wind usually scatters the pollen grains of conifers. The likelihood of pollen reaching female cones is increased when there are large amounts of pollen.
What is pollen analysis?
Pollen grains are the microscopic male reproductive particles released from flowering plants. As these grains are vital for the survival of flowering species, evolution has ensured that individual species produce different types of pollen grains. Pollen grains are also made of a resistant organic material (sporopollenin) that means they are often remarkably well-preserved in sediments many thousands of years old.
Why are pollen grains produce in large nos?
PollenPollen 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.

How does insect pollination occur?
Insects typically pollinate flowers as they move from plant to plant searching for food. Many flowers produce nectar, a sugary liquid that many insects eat. When an insect lands on a flower to feed, pollen grains stick to its body. As the insect moves to another flower of the same species, these pollen grains are transferred to the flower's stigma and pollination occurs. Perhaps the most well-known pollinator insects are bees and butterflies, but wasps, moths, flies and beetles can be pollinators as well.

Do roses have pollen?
Yes carnations have seeds When the flower has finished blooming there will remain seed pods where the flower was just save these and dry them and you can plant them next year.
Do all flowers have pollen in them?
No, they are only half of the equation. Pollen comes from the male parts of the flower. It is necessary for the fertilization of the female flower parts then the seed is fertilized and will be a mature seed that can grow. ----------------------------------------------- NO, pollen is the male gamete which joins with an ovule to make a plant seed.
Why do plant produce so many pollan grains when only one pollen grain is needed for fertilization?
Because some won't find mates. To have the greatest chance of 'breeding' as many times as possible.
