Importance of Plants • As a table, determine what the top five crops (in terms of amount produced) are in Minnesota.
Importance of Plants • Corn is the Minnesota’s most valuable crop followed by soybeans. • Farmers also grow hay, sugar beets, wheat, barley, flaxseed and oats. • The leading vegetable crops are peas, potatoes and sweet corn. • Minnesota's leading fruit crops are apples.
Importance of Plants • Name five uses of these crops: • Corn • Soybeans • Sugar beets • Hay • Apples
Who’s Line is it Anyway? • Roles of a Plant
The Importance of Plants • Without plants, life on earth could not exist • Plants are the primary source of food for humans and animals
Plants most important Roles • Edible plants • Whole plants or portions of plants, such as seeds and fruits, are used as a food source for many types of animals, including humans. • Important food plants are the grains of the grass family (wheat, rice, corn, sorghum, and barley). • About 88 percent of the world’s total caloric intake and about 80 percent of its protein intake comes from plant food sources.
Plants most important Roles • Industrial uses • There are several important products produced from plants, such as wood, fibers, oils, and rubber. • Fibers that are used in textile manufacturing come from cotton, flax, and hemp plants. • The wood from timber production is used to make furniture, homes and many other products. • Many chemicals such as acetic acid, methanol, and turpentine are obtained from trees.
Plants most important Roles • Medicinal uses • Scientists continue to study many different types of plants to try and understand the various chemical compounds found within them. • Many people believe that the key to curing many of our most deadly diseases such as cancer and AIDS may lie within some yet undiscovered plant compound.
Plants most important Roles • Oils • Many plants store oil as a food reserved in the seeds and fruits of the plant. • Most of these plant oils are used in the production of food for humans, but some are used in industry. • The soybean is the most significant oil plant. • Others also play an important role in plant oil production such as coconut, sunflower, peanut, cottonseed, and rapeseed.
