No,most of them are cross pollinated because they are entomophilous i.e pollination by insects.

people use angiosperms by consuming and reproducing one another
Gymnosperms have cones and angiosperms have flowers/fruits
Angiosperms attract pollinators with different methods. Angiosperms have flowers with bright colors, nectar, and special tricks that fool pollinators into carrying their pollen to other angiosperms.
Angiosperms are of economic importance because: In most terrestrial ecosystems, angiosperms account for most of the photosynthetic conversion of radiant energy into chemical energy. Angiosperms thus form the basis for most terrestrial food chains. The vast majority of our food comes directly or indirectly from angiosperms. For example:- all cereal grains and most vegetables, fruits, and nuts are obtained from angiosperms,- most spices are obtained from angiosperms, and- most non-alcoholic and alcoholic beverages are made from angiosperms. Many angiosperms produce chemicals with significant medicinal properties. Other angiosperms produce chemicals with significant effects on the human central nervous system
Angiosperms do not have chloroplasts. Chloroplasts play an important role in photosynthesis and angiosperms do not undergo photosynthesis thus, the absence of chloroplasts.
