Plants are essential to the balance of
nature and in people's lives. Green plants, i.e., those possessing
chlorophyll, manufacture their own food and give off oxygen in the
process called photosynthesis, in which water and carbon dioxide are
combined by the energy of light. Plants are the ultimate source of food
and metabolic energy for nearly all animals, which cannot manufacture
their own food. Besides foods (e.g., grains, fruits, and vegetables),
plant products vital to humans include wood and wood products, fibers,
drugs, oils, latex, pigments, and resins. Coal and petroleum are fossil
substances of plant origin. Thus plants provide people not only
sustenance but shelter, clothing, medicines, fuels, and the raw
materials from which innumerable other products are made.
Plants
are the backbone of all life on Earth and an essential resource for
human well-being. Just think about how your everyday life depends on
plants.
Food: Everything we eat comes directly or indirectly from
plants. Throughout human history, approximately 7,000 different plant
species have been used as food by people.
