Vascular Tissue

specialized to conduct water and nutrients throughout the plant.

Tracheids

hollow plant cell in xylem tissue with thick cell walls that resist pressure.

Xylem

transport subsystem that carries water upward from the roots to every part of the plant.

Phloem

transports solutions if nutrients and carbohydrates produced by photosynthesis.

Lignin

substance that makes cell walls rigid, enables vascular plants to grow upright and reach great heights.

Roots

underground organs that absorb water and minerals.

Leaves

photosynthetic organs that contain one or more bundles of vascular tissue.

Veins

made of xylem and phloem.

Stems

supporting structures that connect roots and leaves, carrying water and nutrients between them.

Rhizomes

creeping underground stem in ferns.

Fronds

large leaves

Sporangia

haploid spores on the underside of their fronds in tiny containers.

Sori

sporangia grouped into clusters.

Gymnosperms

bear their seeds directly on the surfaces of cones.

Angiosperms

bear their seeds within a layer of tissue that protects the seed.

Cones

the gametophytes of seed plants grow and mature within sporophyte structures.

Flowers

seed-bearing structure of an angiosperm.

Pollen Grain

entire male gametophyte is contained in a tiny structure.

Pollination

transfer of pollen from the make reproductive structure to the female reproductive structure.

Seed

an embryo of a plant that is encased in protective covering and surrounded by a food supply.

Embryo

an organism in its early stage of development.

Seed Coat

surrounds and protects the embryo and keeps the contents of the seed from drying out.

Sporophyte

spore-producing plant

Gametophyte

gamete producing plant

Bryophytes

non-vascular plants

Rhiziods

long, thin, cells that anchor ferns in the ground and absorb water and minerals from the surrounding soil.

Gemmae

small, multi-cellular reproductive structures

Protonema

moss spore lands in a moist place, it germinates and grows into a mass of tangled green fillimates.

Antheridia

sperm with whip like tails.

Archegonia

where egg cells are produced.
