angiosperms

A flowering plant which forms seeds inside a protective chamber called an ovary.

Bryophytes

A moss, liverwort, or hornwort; a nonvascular plant that inhabits the land but lacks many of the terrestrial adaptations of vascular plants.

lignin

A strengthening compound found in cell walls of vascular plants is

cellulose

Carbohydrate component of plant cell walls.

Seeds

Carry dormant plant embryos packaged with a food supply.

Gymnosperms

Connifers, cycads, ginkgo and gnetophytes are collectively called

eudicots

Member of a clade consisting of the vast majority of flowering plants that have two embryonic seed leaves, or cotyledons. (beans, Oaks, roses, daisies)

charophytes

Plants probably descended from a group of green algae called

seedless, vascular plants

Plants that have vascular tissue but reproduce by spores (ferns, club mosses, and horsetails)

xylem; phloem

Seedless vascular plants have _________ to conduct water and dissolved minerals and ____________ to conduct disolved sugar

gammae

Structures on mosses and liverworts where a small piece of tissue detach from gametophyte and grow into new plants asexually.

embryo sac

The female gametophyte in flowering plants is also called the

sporophyte

The stage in the life cycle of a plant in which the plant produces diploid spores.

gametophyte

The stage in the life cycle of a plant in which the plant produces haploid sex cells.

Pollination

The transfer of pollen from male reproductive structures to female reproductive structures in plants

Cycads

Type of gymnosperm prevalent in the Mesozic era. Most are near extinction. Palm like leaves and large cones

Gnetophytes

Type of gymnosperm. Mixture of traits. Cones resemble tiny flowers

Ginkgo

Type of gymnosperm. Only one species existing today. No longer found in nature. Fan shaped leaves

Conifers

Type of gymnosperm. Pines with needlelike leaves. Produce eggs/sperms in cones

stomata

allow gas exchange for photosynthesis

Monocots

angiosperms that have only one seed leaf, includes palms grasses and orchids

Dicots

angiosperms that have two seed leaves

cuticle

waxy layer that covers aerial parts of the plant
