In Greenland, the Arctic poppy can be found, rising up out of massive layers of ice. Mountainsides are filled with large, colorful blooms, even when packed in heavy snow. On the other end of the temperate zone, many types of cacti are found in barren deserts that may go for many years with rainfall.
USES FOR PLANTS
FOOD
The chief food plants in many countries are cereal grains. The major types of grain crops include wheat, corn, rice, oats, barley, and rye. Next are legumes, such as peas, beans, soybeans, and peanuts. For centuries, people have used the herbs and spices derived from plants as seasonings for their food. Pepper and nutmeg are two examples of seasonings derived from dried fruit, while others such as sage and rosemary come from leaves. A common baking spice, cinnamon, is found in the stem of the plant.

LUMBER
There are various species of trees used for lumber. These include softwood and hardwood trees.
Softwood trees are generally used to construct structural lumber such as plywood, etc.
Softwood species include: Loblolly, slash, shortleaf, and longleaf pine
Hardwood trees are generally used to construct lumber, furniture, picture frames, etc.
Poplar
Hardwood species include: Red oak, white oak, ash, poplar, and pecan
FIBER
Fiber crops are field crops grown for their fibers, which are traditionally used to make paper, cloth, or rope. The fibers may be chemically modified, like in viscose or cellophane.
Botanically, the fibers harvested from many of these plants are bast fibers; the fibers come from the phloem tissue of the plant. The other fiber crop fibers are seed padding, leaf fiber, or other
