one way is from insects such as bees, picking the pollen up and dispersing it onto the female flower. or the wind can pick up the pollen and it will either float somewhere else or it will blow to a female flower

What is needed for pollination to take place?
In order for pollination to occur, what must happen to the pollen grains is that they have to be transferred to the stigma in a flower of the same species. The stigma is the female part of the flower.
Can seeds form without pollination?
No, because pollen is required for a pollen tube to be created for the sperm cells to move into the ovary and connect with egg cells (the process of fertilization). Because then the one of the pollen's cells will divide, forming two haploid sperm. When the pollen tube reaches the ovule in the ovary, it enters the embryo sac and releases both sperm cells. Then, two fertilizations (also called double-fertilization) take place.
Do all plants need pollinators?
They can't. This is because their pollen cells have different numbers of chromosomes, and therefore reproduction cannot occur. In order for flowers to breed, the pollinator must have the same number of chromosomes in its pollen cells as the flower receiving the pollen.
Why is the number of petals and sepals in a rose not equal in numbers?
The petals of a flower are for photosynthesis (for energy) and for attracting other organisms (with bright colors) such as birds, insects, and mammals that transfer pollen from flower to flower, a.k.a., pollination, in order to reproduce (also see "cross-pollination). The sepals contain more chlorophyll which gives plants their green color, and are used for protecting the flower while in it's "bud stage". Cross-Pollination: When pollen is moved from the male structure of a flower and carried to the female structure of another flower by wind, insects, mammals, and birds, as well as fish on some occasions.
How did gregor Mendel cross pollinate flowers?
Mendel took the pollen from one pea flower and put it onto anothers pistil. In order for there to be no other pollination, he covered them with protective bags, he also moved some into a greenhouse.
Where does the pollen need to be taken in order for a flower to make seeds?
The pollen must be taken from the stamen to its stigma in order for pollination to occur. The common method of pollination is when insects and birds try to get nectar or pollen from the plant.
What must happen to pollen grains in order for pollination to occur?
True pollen comes from artichokes in which farts come from natural gas.
What is needed for pollination to take place?
In order for pollination to occur, what must happen to the pollen grains is that they have to be transferred to the stigma in a flower of the same species. The stigma is the female part of the flower.
WHY IS STIGMA IS STICKY?
So the pollen will stick.
Can seeds form without pollination?
No, because pollen is required for a pollen tube to be created for the sperm cells to move into the ovary and connect with egg cells (the process of fertilization).

Then, two fertilizations (also called double-fertilization) take place.
In plants the term pollinations refers to?
Pollination can be best described as sexual reproduction in plants. This is because the pollination travels from flower to flower in order for the plant to reproduce.
What are the three ways in which pollination can occur?
Self pollination, wind pollination, and insect pollination are the three ways that pollination occurs. Pollination is needed in order for plants to reproduce.
How does wind pollination take place?
The plant contains little pollen particules that get carried by the wind. These plants tend to be more feather like in order to increase their chance of catching the pollen.
How are plants involved in pollination?
Not too sure if its correct but I think its because plants are unable to move on their own in order to get the pollen grains from their anthers to the stigma of another flower for pollination, therefore the rely on external factors.
What are some ways that pollination can happen?
pollination may be self pollination or cross pollination. in self pollination, the pollen grains of the flower falls on the ovary. it occurs in bisexual flowers. in cross pollination, the pollen grains of one flower reaches the ovary of another flower through air, or insects or water. thus the reached pollen grain produces a pollen tube into which the male gamete enter. it reaches the ovule and fertilize with it to produce a diploid zygote.
Do all plants need pollinators?
They can't. This is because their pollen cells have different numbers of chromosomes, and therefore reproduction cannot occur. In order for flowers to breed, the pollinator must have the same number of chromosomes in its pollen cells as the flower receiving the pollen.
Differentiate cross pollination from self pollination?
Self pollination is where the plant is able to pollinate without another plant. This provides much less variation in the genetics of the species from generation to generation than cross pollination which is where the pollen from one plant is carried to another plant (bees usually do this) and fertilizes the other plant. It creates more genetic diversity because the genes from both plants, which are different, are involved in the forming of the seed, not just the genes from the one self-pollinating plant.--------------------------------------------IMPROVEDSelf pollination is the transfer of pollen from the anther to the stigma of the same flower, another flower on the same plant, or the flower of a plant of the same clone. Cross pollination is the transfer of pollen from the flower of one plant to the flower of a plant having a different genetic constitution.
