Does pollination occur before fertilisation?
Yes, pollination is the process of transferring pollen grains from the male reproductive organs of a flower to the female reproductive organs. Fertilization occurs after pollination, when a pollen grain meets the ovule of a flower and forms a seed.
How does the pollen get to the ovule to fertilize it?
Pollen is transferred from the male reproductive organ (anther) to the female reproductive organ (stigma) of a flower through pollination. Once the pollen lands on the stigma, it forms a pollen tube that grows down through the style and delivers the sperm cells to the ovule for fertilization.
What is a ovule part of the female flower?
The ovule is the part of the flower where the embryo sac is housed, and the embryo sac contains the female gamete (egg), which, when fertilized by the sperm in a pollen grain, will produce a zygote. What was once a flower will become a fruit. The zygote develops in the ovule, and forms the seed, which will eventually be dispersed from the fruit to start a new generation. So, the ovule is analogous to the pollen: one contains the female gamete, and the other contains the male gamete.
How does a pollen tube form?
A pollen tube forms when a pollen grain lands on the stigma of a flower and germinates. The pollen grain absorbs water and begins to grow a tube that will penetrate the style of the flower and reach the ovary. This is a crucial step in the process of fertilization in plants.
What will you say that anther forms pollen or pollen grains?
An anther is the male reproductive structure of a flower that produces pollen. Pollen grains contain the male gametes of plants and are essential for the process of pollination, where the pollen is transferred to the stigma of a flower for fertilization to occur.
What are the parts of the flower invoved in pollination?
The male sex organ parts create the pollen. The carpal is the female part of the flower. Inside the carpel is the ovary where the seed forms.
Describe what happens from the time pollen lands on the female part of a flower until a seed forms?
Once pollen lands on the female part of a flower, it germinates and grows a tube through the style to reach the ovule. Fertilization then occurs when the sperm from the pollen combines with the egg cell in the ovule, forming a zygote. The zygote develops into a seed, which contains the genetic information necessary for a new plant to grow.

When pollen hooks up with eggs in the same flower then it makes a?
When pollen fertilizes eggs in the same flower, it forms seeds. These seeds can then develop into new plants through the process of germination.

What grows down the pistil of a flower?
The pistil is the female part of the flower. When pollen is transfered from the stamen of the same flower or another flower of the same or similar type by wind, insects, or q-tips, a seed forms inside the pistil. Plant breeders actually remove the stamen from selected flowers and place pollen from other flowers ion or in the pistil with q-tips so the plant that grows from the seed will have the desired characteristics.
How does the process of fertilisation take place in flowers?
the stamen[male] part of the plant creates a solution called pollen. a insect will come along and when it gets close some of the pollen rubs on the insect. then while it is looking around the flower some of the pollen rubs off on the pistil [female part of the plant]. pollen then go down into the ovary where the eggs are and then the eggs and the pollen combine to form seeds
A pollen grain forms a tube leading to the flower's what?
Pollen grows a tube that travels down to the flowers ovary. From there, the nucleus of the pollen grains passes through the pollen tube to join the nucleus of the ovule to fertilize.
What happens to the ovules of the flower after fertilization?
After Fertilisation:- 1. The Flower looses its bright color. 2. The petals, sepals and stamen withers away. 3. The ovary starts to grow bigger in size. 4. The ovary becomes fruit. 5. The ovules become the seeds of the fruit.
