Unlike the gymnosperms where the ovules are naked, in the angiosperms or flowering plants, the pollen grains and ovules are developed in specialised structures called flowers. In angiosperms, the seeds are enclosed in fruits. The angiosperms are an exceptionally large group of plants occurring in wide range of habitats. They range in size from the smallest Wolffia to tall trees of Eucalyptus (over 100 metres). They provide us with food, fodder, fuel, medicines and several other commercially important products. They are divided into two classes: the dicotyledons and the monocotyledons.
NTA tests students on angiosperm features, particularly the range of sizes (Wolffia as smallest, Eucalyptus as largest) and key distinguishing features like seeds enclosed in fruits and pollen/ovules in flowers. Students commonly confuse angiosperms with gymnosperms—remember: angiosperms have ENCLOSED seeds in fruits, while gymnosperms have NAKED ovules. Another trap is forgetting the two angiosperm classes: dicotyledons and monocotyledons. To score correctly, memorize that Wolffia is the smallest flowering plant and that all angiosperms produce flowers and fruits—these are their defining characteristics that differentiate them from gymnosperms.
