Unlike such nonvascular plants as the bryophytes, in which all cells in the plant body participate in every function necessary to support, nourish, and extend the plant body (e.g., nutrition, photosynthesis, and cell division), angiosperms have evolved specialized cells and tissues that carry out these functions and have further evolved specialized vascular tissues (xylem and phloem) that translocate the water and nutrients to all areas of the plant body. The term "angiosperm" derives from two Greek words: angeion, meaning "vessel," and sperma, meaning "seed." The molecular data indicate the seed plants most closely related to the angiosperms are the gnetophytes and bennettitaleans, which, incidentally, is the same conclusion reached by some botanists using morphological and anatomical features 50 years ago.

The flowers are the largest and most species-rich phylum of plants to land! The characteristic reproductive structures of the Angiosperms are the flowers. The cuticle, a waxy layer on the surface of leaves and stems, also prevented water loss by reducing evaporation. Various organisms solved these problems in different ways, resulting in physical differences between tissues and chemical alterations that increased the genetic variation of plant species. Was Mike Hamernik Married, Gymnosperms and angiosperms have a life cycle that involves the alternation of generations, and both have a reduced gametophyte stage. Bunker Hill Redevelopment Project, The ovules in angiosperms are encased in an ovary, not exposed on the sporophylls of a strobilus, as they are in gymnosperms. ADVERTISEMENTS: 3.
