To answer the question, we need to understand the process of fertilization in flowering plants, specifically focusing on the roles of the male gametes. ### Step-by-Step Solution: 1. **Understanding the Pollen Tube Function**: When the pollen tube reaches the ovary, it releases two male gametes. This is a crucial step in the fertilization process. 2. **First Male Gamete Fusion**: The first male gamete fuses with the egg cell of the ovule. This fusion results in the formation of a diploid zygote, which is also referred to as an **oospore**. The oospore will eventually develop into the embryo of the seed. ...
