What does an interaction between pollen grains and its compatible stigma result in after pollination? List two steps in sequence that follows
after the process.
Answer:
When the pollen grains fall on the stigma, they germinate and pollen tube enters one of the synergids and releases two male gametes:
- One of the male gametes move towards the egg cell and fuses with it to complete syiigamy to form the zygote.
- The second male gamete fuses with the two polar nuclei and forms primary endosperm nucleus (3n). This is termed as triple fusion.
- Since two kinds of fusion - syngamy and triple fusion takes place, the process is called double fertilization and is characteristics of flowering plants.
