What happens to the tune nucleus after the pollen tube has penetrated the ovule?

Upon reaching the ovule the pollen tube ruptures, thereby delivering the sperm cells to the female gametophyte, ultimately resulting in a double fertilization event. The first fertilization event produces a diploid zygote and the second fertilization event produces a triploid endosperm.

1. a host loses nutrients to a parasite

2. a parasite only benefits when the host is alive (cause if the host dies the parasite dies with it )

3. producers to consumers
