Plant/pollen fertilization?

Plants typically produce many more pollen grains than there are ovules to fertilize. What is the advantage of doing this?

Plant/pollen fertilization?
To maximize the number of ovules that are fertilized. To increase the probability that all ovules are fertilized.



The cost of the production of extra pollen is far less to the plant species than the possibility of an ovule not being fertilized.
Reply:indeed the pollen grains are a lot more than the ovules. The advantage of this is that it may not be many fertility assistants in the area, like honeybees or for those plants who are helped being fertilized by the wind, it may be not windy. Also, there's a chance that not all pollen grains are fertile or be sure that all pollen grains will be fertilized.
