Our reliance on seed plants makes preservation of plant diversity critical Products from Seed PlantsMost 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 Threats to Plant DiversityDestruction of habitatis causingextinction of many plant species
