	works the same way in all plants
	does not have potential agricultural applications
	is based on the same mechanism of transplant rejection seen in animals
	maintains variation
	is the rejection of a graft by a plant

	Each one fertilizes a separate egg cell.
	One fertilizes an egg, and the other fertilizes the fruit.
	One fertilizes an egg, and the other is kept in reserve.
	Both sperm fertilize a single egg cell.
	One fertilizes an egg, and the other combines with a cell that develops into stored food.

	is a specialized cotyledon found in certain monocots
	develops into the seed coat
	presents a barrier to self-fertilization
	is a specialized cotyledon found in eudicots
	is the embryonic root

	depends on the growth of the embryo rupturing the seed
	depends on imbibition
	depends on maturation of the embryo
	occurs after a certain species-specific period of time
	results in the cotyledon being the first structure to emerge from the seed
