Pollen grains require a compatible and mature stigma to germinate and grow a pollen tube for fertilization. If pollen lands on an unripe stigma, it may not provide the necessary biochemical signals or nutrients for the pollen to survive and develop. Additionally, the stigma may lack the appropriate receptors or conditions needed for pollen germination, leading to the pollen's eventual death. Ultimately, the failure to establish a successful connection between the pollen and stigma prevents fertilization.

How does pollen make it from the stigma down to the ovary?
It makes a seed Edited answer: In nature, pollen does not get into ovary, rather it land on the stigma and their it allowed to germinate to send pollen tube to the ovary only if it is compatible. Otherwise it is rejected by the stigmatic cells and withers away.

What do flowering plants reproduce from?
The answer is that the male part of a flower ( the stamen ) has a part called the anthers, these have the pollen on it, when the pollen touches the stigma ( a part of the female part of a flower) it travels down the style and into the ovary which contains the ovules or baby seeds these seeds are fertilized and after a little time the flower dies and the seeds start a new plant, starting the process all over again.

Is pollen released from flower before it dies?
Yes, pollen is typically released from a flower before it dies. This is because pollen serves the purpose of fertilizing other flowers to produce seeds and new plants. Once the pollen has been released and pollination has occurred, the flower may wither and die.

Do bees pollinate cucumbers?
Most grasses, including sugar cane, are pollinated primarily by wind. The plants produce large amounts of pollen which wind and gravity carry onto the pistils. In addition, Mexican free-tailed bats (Tadarida brasiliensis) pollenate sugar cane as they fly among the canes in pursuit of insects.
How does pollen last for thousands of years?
umm a flower dies and it comes back to life and the ploen was never alive so it cant die but it will get blown around
What happens the petal after fertilization?
When a pollen grain lands on the stigma of a flower, whether deposited there by an insect or the wind or by any other means, fertilization of the flower may follow. The pollen develops a tube which grows down through the stigma and style, enters the ovary and in to the ovule. The male sex cell which is carried in the tip of the tube fuses with the female sex cell in the ovule and fertilization is complete.There is a slight complication: there are two male nuclei in the pollen tube and the second one fuses with another nucleus in the ovule, called the primary endosperm nucleus, and this develops into a food store, called the endosperm, which nourishes the developing embryo plant. An example of endosperm tissue in a seed is the large, starchy part of a grain of wheat, the embryo plant develops from the wheatgerm.
