Tree is a tall plant that has complete structures, such as root, stem, branches, twigs, leaves, flowers, and also fruits.

Commonly, tree grows on the ground. Inside the ground, there are water, mineral, and dissolved materials.

We can also find the most important part of tree, in the ground. this part is called root. There are two kinds of root that have different size and function. The first is tap root, and the second is fibrous root. Tap root has big size, and it grows downward. The function is to hold the plant in upright position against the strong wind. While fibrous root is tiny, like hair and fiber and it grows outward. Although the size is very small, fibrous root has important role. It's used to absorb water, mineral, and dissolved materials which are needed by the tree to grow.

The part of tree that's connected directly to root is trunk or stem. Trunk is protected and covered by tough material called bark. Trunk also plays important roles for the tree. The function is to conduct water, mineral, and dissolved materials from root to leaves through a tissue called xylem. While to conduct the result  of photosynthesis process from leaves to entire part of tree is done through phloem. Even in several kinds of tree such as sugar cane and sago, trunk is used for food storage.

There are small trunks called branches on the trunk. Branches are the place where twigs are found. Twigs are also stem, but it's the smallest stem. The function is as the place of flowers, shoot, and fruits to grow.

One more important part of tree, that is leaves. Generally, the color of leaves is green because they contain chlorophyll. Leaves have two functions. The first is to make food through photosynthesis process. To do this process, leaves need water and carbon dioxide with the help of sunlight. As the result, there are amylum and oxygen. The second function is to reduce air pollution, because leaves inhale carbon dioxide from the air and exhale oxygen to the air. In this case, purification process occurs. This function can be felt directly by human.

Tree has beautiful part. That's flower. Flower is a part of tree that has various colors. It consists of anther, petals, sepals, stalk, and bud. Anther is part of flower that can do pollination with the help of insects, wind, or human. To attract insects, flower has petals, because petals have various colors and shape, and also give off fragrant smell. To support petals, there is sepal or calyx. While to support the whole parts of flower is stalk or stem of flower. The closed flower before it blossoms is called bud. In several kinds of plant, such as roses and orange, we can find the another part called thorn or sharp-pointed shoot, that grows on the stalk.

The last part of tree is fruit. Fruit also has stalk to support the whole fruit. Commonly, fruit can be eaten. The part to be eaten is flesh or the meat of fruit. Fruit is covered by peel, to protect the flesh from dirt. Like human and animal, tree needs to breed. The part that can produce new plant is seed. The seeds that have big size are called stones. If we plant seeds in the ground, they will grow into new plants.

Previously, I had posted batik from Yogyakarta. This time, my art teacher gave the similar assignment, with the range of Sumatera. I can say that it was difficult enough for me to find the easy batik pattern from Sumatera. So, I ended up browsing Sumatera ornament. Finally, I found this ornament, ornament of Siwaluh Jabu custom home, from Batak Karo, Sumatera.

For this task, I got better score than before :D

Well, that's what I can say. I hope this help you even a little. Oh, and don't forget to explore other cultures of Indonesia! We have a lot of creations which aren't well-explored yet!
