Structure and Function of Stem

Rod on plants have shape and size are very diverse. There branched stems and some are not branched. There is a rod that is small and some are very large in size, such as the type of Giant Sequoia trees. This tree has a height of 85 meters with an estimated age of about 2200 to 2700 years. This tree is considered to be the largest tree in the world in terms of volume. The volume of this tree in 2002 amounted to 1487 cubic meters. Sherman tree with Giant Sequoia type, located in Sequoia National Park in Visalia, California.

Stem usually serves to support the parts of a plant that is above ground, uphold and strengthen the plant body, with ramifications extending the field of photosynthesis, road transport water and minerals from ground, and the results of photosynthesis can be distributed to all parts of the plant until to roots. In addition, as a place to store food reserves. For example, the sugar cane plant, cactus, and potatoes. Stem can also serve as a breeding tool such as cassava stems, ginger, and mango crops.

Structure and Function of Root

Morphological structure is a picture of the outside of the body of an organism. The structure of higher plants, such as Angiosperm and Gymnosperm can be described as follows. Morphological structure of higher plants generally consist of roots, stems, and leaves. At a certain stage in its development, plants can form flowers, fruits and seeds. The structure of plant morphology Angiosperm group is related to the condition of the environment in which his life. At the same time, plants have to extract resources from the land and air. Water and minerals from the ground, while the air is where the availability of CO2 and sunlight can not penetrate the soil. Therefore, the plant has a root system under the ground and shoot system is above ground level. Each system need each other.
