Define mesogamy and anemophily

Answer

**Step-by-Step Text Solution:**

1. **Definition of Mesogamy:**
- Mesogamy is a type of fertilization in flowering plants where the pollen tube penetrates the ovule to deliver male gametes.
- The ovule contains the embryo sac, which is the female gametophyte or the female gamete (egg).
- The entry of the pollen tube occurs through the integuments, which are the outer coverings of the ovule.
- This process is observed in plants such as pumpkin and bitter gourd.

2. **Definition of Anemophily:**
- Anemophily refers to a type of pollination that occurs when pollen grains are transferred from the anthers (the male part of the flower) to the stigma (the female part) by the wind.
- This method of pollination relies on wind as the primary agent for transferring pollen grains, and it is commonly known as wind pollination.
