Tree

A tree is where everyone starts out in Minecraft. They must punch a tree to gather Wood which are used to make Wooden Planks and along with Sticks  to make tools and other items to upgrade their home, kill livestock and to mine other resources for better Tools. Trees are grown when you break some leaves off a tree and a Sapling or Apple has a chance to drop. You can randomly place a Sapling anywhere with enough space and light, and a tree will grow in a matter of time, or can be instantly grown using Bone Meal, but it depends how much space there is between the tree and wall. Apples can be eaten to bring back 2 hearts.

Trivia

 * There are three different types of trees: Oak, Birch and Spruce. Other trees not in PE include Jungle, Acadia, and Dark Oak.
 * If trees did not exist in Minecraft, you would not be able to do anything, so dont take trees for granthood ;)
 * Almost every object in one way or another needs wood to be obtained.
