1,200 WORDS. Discuss how adaptations allowed plants to move from an aquatic environment to the variety of habitats they inhabit today. You may wish to start out discussing single celled algae and include the transition from prokaryotes to eukaryotes. At the beginning or end of the essay, it may be helpful to write about plants that you have observed (using correct Scientific nomenclature), and consider their traits and habitat. Then explain why those traits are adaptive, and how they arose. Don’t forget the role of natural selection in adaptation.
