Seed Plants exam Flashcards

The dominant life cycle stage in seed plants, producing spores.

Angiosperms and gymnosperms.

Producing two types of spores: microspores and megaspores.

It is the outer protective layer of the ovule.

Seed plants that produce seeds within fruits.

A process in angiosperms where one sperm fertilizes the egg and another forms the endosperm.

Seed plants that produce naked seeds in cones.

Embryonic leaves contained in the seed.

Angiosperms with one cotyledon.

It provides nutrition for the developing embryo.

Angiosperms with two cotyledons.

Flower traits evolved in response to pollen vectors like wind, bees, and birds.

A flower that contains sepals, petals, stamens, and pistils.

The opening at the apex of the integument in an ovule.

A flower that has both male and female structures.

Monoecious plants have both male and female flowers on the same plant, while dioecious plants have them on separate plants.

The male part of the flower, consisting of the filament and anther.

It is the female part of the flower, consisting of the stigma, style, and ovary.

Transfer of pollen from one plant to a different plant of the same species.

When a plant fertilizes itself using its own pollen.

The transfer of pollen to the ovule.

A group of gymnosperms known for their needle-like leaves and cones.

The structure that contains the megasporangium and develops into a seed after fertilization.

It digests its way through the ovule to deliver sperm to the egg.

The outer protective layer of the ovule.

It encases and protects the flower bud before it opens.

The developing plant within a seed.

It encloses the ovules and develops into fruit.

The male gametophyte covered by a tough pollen wall.
