• Vascular plants-plants with vascular tissue; pteridophytes, gymnosperms, and angiosperms; includes all modern species except the mosses and their relatives • Vascular tissue-plant tissue consisting of cells joined into tubes that transport water and nutrients throughout the plant body • Pteridophytes-seedless plants with true roots and lignified vascular tissue; ferns, horsetails, and whisk ferns • Bryophytes-nonvascular plants; lack water conducting tissues and have no true roots; though to have diverged from charophyceans due to differences in reproductive strategies; multicellular embryo develops from zygote that is still attached to tissue of the female parent; mosses, liverworts, and hornworts • Seed-An adaptation for terrestrial plants consisting of an embryo packaged along with a store of food within a resistant coat • Gymnosperm-vascular plant that bears naked seeds

• Angiosperms-flowering plants, which form seeds inside a protective chamber called an ovary • Charophyceans-green algal group that shares 2 ultrastructural features with land plants; considered to be closest relatives of land plants • Rosette cellulose-synthesizing complexes-rose-shaped array of proteins that synthesize cellulose microtubules of cell walls of charophyceans and land plants • Peroxisome-microbody containing enzymes that transfer hydrogen from various substrates to oxygen, producing and then degrading hydrogen peroxide • Sphenophytes-class of plants with a fossil record going back to the Devonian. They are commonly known as horsetails. Living species typically grow in wet areas, with needle-like leaves radiating at regular intervals from a single vertical stem. • Psilophytes-Any of an order of extinct, alternately branched plants from the Paleozoic Era. This order includes the earliest known terrestrial plants with a vascular structure. • Microspore-spore from a heterosporous plant that develops into a male gametophyte with antheridia • Apical meristem-embryonic plant tissue in the tips of roots and in the buds of shoots that supplies cells for the plant to grow in length • Placental transfer cells-plant cells that enhance the transfer of nutrients from parent to embryo • Embryophytes-another name for land plants, recognizing that land plants share the common derived trait of multicellular, dependent embryos. • Gametophyte-the multicellular haploid form in organisms undergoing alternation of generations that mitotically produces haploid gametes that unite and grow into the sporophyte generation • Sporophyte-multicellular diploid form in organisms undergoing alternation of generations that results from a union of gametes and that meiotically produces haploid spores that grow into the gametophyte generation • Spores-In the life cycle of a plant or alga undergoing alternation of generations, a meiotically produced haploid cell that divides mitotically, generating a multicellular individual, the gametophyte, without fusing with another cell • Sporopollenin-A secondary product, a polymer synthesized by a side branch of a major metabolic pathway that is resistant to almost all kinds of environmental damage; especially important to the evolutionary move of plants onto land • Sporangia-multicellular organ found on the sporophyte that undergoes meiosis to produce haploid spores • Gametangia-multicellular organ that produces gametes and provides a jacket of nonreproductive cells to prevent dessication • Spore matter cell-cells that undergo meiosis and generate haploid spores within a sporangium • Antheridia-vase-shaped organ that gives rise to eggs; female gametophyte • Sporophyll-lycophyte leaves specialized for reproduction • Deep green-focuses on deepest phylogenetic branching within the plant kingdom to identify and name the major plant clades (monophyletic group) • Rhizoids-long tubular single cells or filaments of cells...
