Which organisms does the term germination apply to?

What are empty seeds which never germinate?

The SI unit of pressure is the Pascal (Pa).
The unit of pressure defined as 1/760 of standard atmospheric pressure is the Torr.
Gauge pressure is measured relative to atmospheric pressure, often considered zero reference.
The traditional measure of pressure in imperial and US customary systems is pounds per square inch (psi).
Pressure can also be expressed in terms of the height of a fluid column in a manometer, commonly using the millimeter of mercury (mmHg).

Germination in seed plants results in the growth of new plant structures, specifically roots and shoots.
The process of reactivating the metabolic machinery of the seed leading to the emergence of the radicle (root) and plumule (shoot) is called germination.
Fully developed seeds of most plant species contain a complete embryo, stored nutrients, and a protective seed coat.
The term germination applies primarily to seed plants, including angiosperms and gymnosperms.
Empty seeds that never germinate are termed non-viable seeds.
