Question

What happen in compatible pollen pistil interaction?

Answer 1

Pollen grains are deposited on the stigma either due to closeness of the anthers to the stigma or by pollinating agents (biotic or abiotic). This unique feature brings about pollen-pistil interaction between the male gametophyte, the pollen grains, with the massive sporophytic tissue.

A successful pollination brings about sequential events in the pollen-pistil interaction that ultimately ends up by the discharge of the male gametes in the embryo sac

Pollination->pollen adhesion >pollen hydration >pollen germination >pollen tube entry into stigma>pollen tube growth through the style>pollen tube entry into the ovule and embryo sac > double fermentation

All the events beginning from pollination to the release of gametes in the embryo sac form a part of the pollen-pistil interaction or the programic phase.

Answer 2

Answer:

In real-time interactive audio/video, people communicate with one another in real time. The Internet phone or voice over IP is an example of this type of application. Video conferencing is another example that allows people to communicate visually and orally
