Should you plant the whole sunflower seed or just center?

Here's why:

* The seed coat protects the embryo: The seed coat provides a protective layer for the developing embryo inside.

* Provides nutrients for germination: The seed coat contains essential nutrients that the embryo needs to germinate and grow.

* Improves germination rate: Planting the whole seed improves the chances of successful germination.

Planting just the center of the seed (the embryo) would make it very difficult for the seed to germinate and grow.
