Nabila Anika • 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
