Angiosperm

Corn, wheat, rice, and other cereal grains are among the most important angiosperms because they serve as a primary global source of food and energy for humans and domesticated animals.12
These plants, all members of the grass family (Poaceae), are vital for several reasons:
- Energy Storage: Angiosperms convert solar energy into starch, which they store in the endosperm of their seeds to support seedling growth. This energy-rich starch provides the fundamental caloric requirement for much of the world's population.13
- Economic Efficiency: Compared to other food sources, cereal grains are highly cost-effective to produce per calorie and can be stored dry for many years, ensuring food security.3
- Versatility: Beyond direct human consumption, these grains are used for livestock feed, malting, and the production of various industrial goods, including cosmetics, adhesives, and biofuels.14
While their nutritional profile—specifically protein quality—varies, they remain the cornerstone of human nutrition and global agricultural systems.13
