Unit Topics
1. Analyze how the increasing complexity of gymnosperms and angiosperms contribute to survival in a land environment
a) Examine gymnosperms and describe the characteristics that unify themb) Explain how gymnosperms are adapted for survival in a land environment with respect to the following: alternation of generations, roots, stems, leaves, seeds, pollen, vascular tissue (p.348 to 349)c) Examine angiosperms and describe characteristics that unify them (p.350 to 351)d) Use specimens to differentiate between monocots and dicots (p.623 )e) Describe how angiosperms are adapted for survival in a land environment, with respect to alternation of generations, flowers, pollen, enclosed seeds, fruit, roots, stems, leaves, vascular tissuef) Compare the ways in which mosses, ferns, gymnosperms, and angiosperms have adapted to a land environment (p.342 +)
Overview: Transforming the Worlda) The seed arose about 360 million years ago.i) A seed consists of an embryo and its food supply, surrounded by a protective coat. ii) When mature, seeds are dispersed from their parent.iii) Because it nourishes and protects the embryo yet can separate from the mother plant, a seed is analogous to a detachable, mobile uterus.b) Seeds are the key adaptation that enabled seed plants to be the dominant producers on land, making up the great majority of plant biodiversity.c) Agriculture, the cultivation and harvest of plants (especially angiosperms), began 12,000 years ago.i) Humans began to cultivate plants independently in various regions, including the Near East, East Asia, Africa, and the Americas.d) The cultivation of plants was the single most important cultural change in the history of humanity; it made possible the transition from hunter-gatherer societies to permanent settlements.
