What is imbibition?

Imbibition is water absorption that swells seed tissues at the start of germination.

Which hormone generally maintains dormancy?

ABA helps establish and maintain dormancy, while GA promotes germination.

Why does a waterlogged seed often fail?

Saturated pores slow oxygen diffusion needed for continuing metabolism.

What usually emerges first from a germinating seed?

The radicle commonly breaks out first to anchor the seedling and absorb water.

When does a seedling become less dependent on stored food?

Expanded green leaves begin producing sugars through photosynthesis.
