Seed Plants and Angiosperms

This set of flashcards covers key vocabulary related to seed plants, gymnosperms, angiosperms, and their reproductive structures.

Gymnosperm

Seed plants that have 'naked' seeds not enclosed in chambers.

Pollination

The transfer of pollen to the ovule.

Angiosperms

Seed plants that develop seeds inside chambers called ovaries.

Floral Organs

Reproductive structures in flowering plants including anthers, filaments, petals, stigma, style, and ovaries.

Seed Structure

Fruit Adaptation

Features that assist in dispersal, such as parachutes, propellers, or burrs that cling to animals.

Pollen

A male gametophyte developed from haploid microspores.

Pines, Conifers, Cycads

Examples of gymnosperms.

Ecosystem Dominance

Gymnosperms replaced nonvascular plants as climate became drier, dominating terrestrial ecosystems.

Ovules

Structures that seeds develop from after fertilization.
