The ovary in the flower must be fertilised by pollen from the stamen and then seeds can form.

Do all trees release pollen?
Not all plants need to make seeds. Ferns and mosses for example do not have to produce seeds to spread.
Why does marijuana have so many seeds?
It must of somehow been pollinated during flowering... and or was a male plant. Female plants produce no seeds.
Where on the sun flower are the sunflower seeds?
A sunflower seed grows into a sunflower with more seeds. A seed must flower before making more seeds. Each flower produces over 1000 seeds.
Which part must be able to find in a flower to conclude that it is a insect pollinated flower?
Colourful petals. Plants that are not insect-pollinated are most often inconspicuous such as grass (which does have flowers!) or pines (which don't really have flowers but to produce massive amounts of pollen in spring, just because the wind is so random).
When does pollination take place?
A flower is pollinated when a bee drinks it's nectar. The bee will have pollen (a dust like substance) trapped on the hairs of it's legs from other flowers. Pollen from the flower gets trapped on the bee, and pollen trapped on the bee's legs get in the flower. This is how a flower is pollinated.
How do you get seeds out of an African violet?
To produce seeds, the African violet must be pollinated, either by itself (rarely happens), by insects (happens sometimes) or by human intervention. African violets have both male and female attributes so they can be "self-crossed" or pollinated with pollen of any other African violet. When pollination works, a seed pod will appear at the base of the flower. You have to wait until the pod grows, and dries (it turns brown). The whole process can take up to 9-10 months. When the seed pod is mature, you only have to gently open it with a sharp knife and get the seeds. One seed pod usually produce at least 500 seeds (seeds are almost as small as dust).
How is wind pollinating a flower similar to an insect pollinating a flower?
They both produce pollen, therefore they must have anthers and since they both produce seeds they must have stigmasThe end results of wind pollination and insect pollination are the same, the plants are pollinated.Wind pollinated plants, which include the grasses and some trees, have either no flowers or very insignificant flowers because they have no need to attract insects. The anthers produce very large amounts of very small pollen grains which are then blown by the wind in the hope of hitting a stigma of the same variety of plant. This is the type of pollen which is the major cause of hay fever.Insect pollinated plants will have flowers, usually with nectar, to attract the insects and reward them with food. A bee's body is covered with fine hairs which become charged with static electricity as the insect flies so when it lands on the flower the pollen grains are actually attracted to the bee's body. When the bee goes to the next flower, some of this pollen is transferred to the flower's stigma. Pollen grains of insect-pollinated plants are much larger than those of wind-pollinated plants.
How many ovules must be fertilized for a flower to produce 10 seeds?
generally one ovule is converted in to one seed after fertilization so 10 seeds 10 ovules must be fertilized.
Are pine trees sexual?
A pine tree reproduce by sexual reproduction. Pine trees produce cones with seeds by sexual reproduction and these cones must be pollinated.
What makes fruit and vegetable organic?
To be organic, watermelon must be grown from non-GMO seeds and synthetic pesticides cannot be used. Usually, the seeds used are heirloom and open pollinated.
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.
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.
