* Most pine absorbs sunlight
  - attracts beetles
* Most pine has bark
  - lives in areas
* Most pine relies on pollination
  - wind pollination
* Most pines are fairly drought- tolerant and can become stressed by overwatering
  - important resources for wildlife, both for food and cover
  - grow rapidly and form straight, tall trunks that are ideal for lumber
* Some pine grows at elevation.
* Some pine grows in countries
  - other countries
* Some pine has ages
* Some pine martens eat insects
  - live in woodlands
  - use cavities
* Some pine produces edible nuts
* Some pine shavings release compounds
  - volatile compounds
* Some pines have needles in groups of three
  - occur throughout the state
  - produce resin, a substance used to make such products as turpentine, paint, and soap.
  * live in almost the entire Northern Hemisphere. In North America, they live in the southern part of Arctic to Nicaragua and Hispaniola. In Europe, they live in areas from Portugal and Scotland to Russia. In Asia, they live in areas from Russia to Japan and the Philippines
* also are easier to care for than hardwood trees
  - grow well in dry conditions in part because their waxy needles conserve water
  - have several insect problems
* anchor themselves with a strong taproot in sandy or well-drained soils.
* are a storehouse of basic materials
  - subgroup of the conifers, which includes all cone-bearing trees
  - conifers , and are neither monocots nor dicots
  - evergreens with long, needle-shaped leaves
  - exceptions to the airborne pollen rule
  - most susceptible to fire when in a young plantation
  - of great importance to wildlife
  - pruned in a special way, called candling, to control growth
* are subject to a number of fungal diseases and insect pests
  - attack by several species of bark beetles
  - well-known survival food plants
* belong to a group of plants called conifers.
* can grow to be very large
  - therefore outcompete angiosperms in sandy soils
* do have a tap roots that goes straight down
  - well in sandy soils and also in sandy loam soils
* furnish the bulk of the southern and eastern pole timber.
* give landowners a quicker harvest because they generally grow faster than hardwoods.
* grow best in full sun on well-drained, acid soil
  - throughout the Southeastern United States
  - very rapidly in the Timberlands Region, which provides a continues supply of wood
  - worldwide and are the most important conifers that grow in the Northern Hemisphere
* grows in climates.
* has appearances
  - tolerance
* have long needles in clumps of two to five
  - long, slender needles in groups of two to five
  - two kinds of cones on the same tree, pollen cones and seed cones
  - winged seeds
* hold their needles the best even when they dry out.
* includes bark
  - cell membranes
  - cytoplasm
  - nuclei
  - pinecones
  - sections
  - stumps
  - vacuoles
  - xylem
* is conifers
  - soft wood
  - software
* let in sunshine and there are fossilized rocks in abundance.
* produce a cluster of buds only at the end of the current season's growth
  - cones each year
  - copious amounts of spring pollen
* provide excellent cover for roosting and daytime resting
  - favorite nesting sites for mourning doves and roosting places for robins
* rank as the world's most important source of timber.
* seed very efficiently from pine cones.
* serve as valuable roosting places for birds and as cover for wildlife.
* severely infested by the beetles usually die.
* shed their oldest needles in autumn.
* stay green even in winter dusted white with a light snowfall about once a year.
* tends to be lower in cost and works a little better in masking the scent.
* use male and female cones for reproduction instead of flowers.
