How does the structure of the pollen grain helps it to move from one flower to another?

The male sex cell in a plant?
The male sex cell in a plant is called a pollen grain. It is produced in the anther of a flower and is responsible for fertilizing the female sex cell, located in the ovule, during the process of pollination.
What is the posh word for when the pollen from one flower reaches to another flower?
posh word for when the pollen from one flower reaches another
How do bees fertilize?
They carry pollen from flower to flower the pollen from one flower fertilizes other flowers and so on.
The purpose of a pollen grain on a flower?
The purpose of pollen is to transfer the male reproductive cells (sperm) to the female reproductive cells (ovules) and thus to allow sexual reproduction. Pollen can be so transferred by many methods - wind, gravity, insects, etc. The pollen receptive part of the flower (the stigma) is often sticky, or textured so the pollen will stick. Once attached the pollen grain grows a tube into the stigma and down the style into the ovule. This tube allows the male gametes to fertilise the ovule, creating a seed.
What is the function of pollen?
Pollen is the plants mechanism of transferring haploid (n) male genetic material (male gametophytes) from the anther of one flower to the stigma of another (cross-pollination) or from the anther of one flower to the stigma of the same flower (self-pollination).The pollen grain is hard and encapsulates the genetic materials (of one parent) with in, in very much the same way that a seed contains the genetic material of both parents.Pollen is small (sometimes microscopic), light and can travel far by wind or attached to insects (bees, moths, butterflies).In angiosperms pollen is produced in the anther of the flowers, in gymnosperms it is produced in the male cones of the plant.When the pollen grain lands on the stigma of suitable flower (very closely related species or same species) the pollen grain germinates; a pollen tube grows down the style and into the ovary (controlled by the generative and tube nucleus - which were contained in the pollen grain) of the flower, here it releases two sperm nuclei which fuse with the haploid (n) nucleus of the ovule to form a zygote.Pollen is made in the male part of the flower (anther) and is full of genetic material. When the pollen and the ova (egg) are joined the DNA from the pollen enters the ova and joins with its DNA. This is fertilisation and the fertilised ova grows into a seed. (pollen has a similar job to do for plants that sperm does for animals).
How does pollen that fertilizes the egg reach the ovule?
Some of the pollen grains carried by wind,insects,birds or bats may reach a carpel and stick to the ripe stigma.Each pollen grain produces a tiny tube which grows down to the style,into the ovary and towards the ovules or egg cells.when one of the tubes reaches an ovule,it bursts open.A male nucleus from the pollen grain then moves down the pollen tube to join with the nucleus of the female sex cell,the ovule.when the nuclei of the pollen grains and ovules have joined together, the ovules are said to be fertilized.
Why does a pea pollen grain contain only one flower colour allele?
Because during gamete formation,one member of the allelic pair separates from one another to form the genetic constitution of the gamete (the gene responsible for flower colour of the allele will occur singly due the separation of the members of the allelic pair).
Where is pollen made in a flower?
Pollen is made by the anther. sexual analizer
What is the combination of material from a pollen grain with an egg to form a seed?
The combination of material from a pollen grain with an egg to form a seed is what bees carry from one plant to another, unknowingly. When the bee lands on a plant it picks up pollen and carries this to another plant.
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
What is one way that pollen can get from the anther of a flower to the stigma of another flower?
It is transferred by wind or bees.
