Concept 30.4: Human welfare depends greatly on seed plants • No group of plants is more important to human survival than seed plants • Plants are key sources of food, fuel, wood products, and medicine • Our reliance on seed plants makes preservation of plant diversity critical Copyright © 2008 Pearson Education, Inc., publishing as Pearson Benjamin Cummings
Products from Seed Plants • Most of our food comes from angiosperms • Six crops (wheat, rice, maize, potatoes, cassava, and sweet potatoes) yield 80% of the calories consumed by humans • Modern crops are products of relatively recent genetic change resulting from artificial selection • Many seed plants provide wood • Secondary compounds of seed plants are used in medicines Copyright © 2008 Pearson Education, Inc., publishing as Pearson Benjamin Cummings
