Give a reason for each of the following :
Pollen grains of wind pollinated flowers are produced in large quantities.

Explanation

**Step-by-Step Solution:**

1. **Understanding Wind Pollination**: Wind pollination, also known as anemophily, is a type of pollination where pollen grains are transferred from the male parts of a flower (anthers) to the female parts (stigmas) primarily by wind.

2. **Wastage of Pollen Grains**: In wind-pollinated flowers, a significant amount of pollen grains are lost to the environment. This is due to the fact that wind can carry pollen away from the flower, and many grains may not reach any stigma at all.

3. **Low Probability of Successful Pollination**: Because of the high wastage, there is a lower probability that the pollen grains will successfully land on a compatible stigma. This means that for effective reproduction, more pollen grains need to be produced.
