Pine trees or conifers come in all shapes and sizes, although most are quite large trees. They all have some features in common. They all have cones instead of flowers. They all have leaves that look like thin green needles. Most pine trees grow from one central point at the top of the tree only and do not branch, which gives most pine trees a distinctive cone shape. Some species do branch, but not as much as most other trees do.
Because pine trees usually grow tall and straight without branching they are commonly grown as plantation timber to harvest their wood for building houses and furniture out of.

Pistachios are the seeds of a medium sized tree native to Iran, Syria, Greece, Turkey, Pakistan, and Afghanistan. They are also called the green nut. The trees are slow to mature and are most productive at 20 years old. The trees grow best in desert areas, and tolerate very salty soil.
Pistachio shells pop open when they are ripe. They are most often sold roasted and salted and just eaten plain, but they can also be used in desserts and some other types of food.

Scientific name: families nepenthaceae and sarraceniaceae
Pitcher plants, like venus fly traps and sundews, are carniverous plants. They eat insects because they grow in very poor soils and need the extra nutrients.
Pitcher plants catch insects in deep pitchers that have smooth sides and something sweet at the bottom to attract insects. When an insect is caught inside, the lid of the pitcher closes. Some pitcher plants grow large enough to catch small animals.
