Root
Type root
Generally, there are two types of roots, namely:

1. Fibers Root. Root is generally found in plants monocots. Although sometimes, dicotyledonous plants also have (with notes, dicotyledonous plants are propagated by grafting or cuttings). The main function of root fibers is to strengthen the establishment of the plant.
2. Tap root. These roots are generally found in dicotyledonous plants. Its main function is to store food as an example: carrots, potatoes and so on in the form of tubers.

• Hanging roots. Hanging roots grow from the top of the stem and grow towards the ground. Therefore, the roots can be seen hanging in the air. This suspension serves roots absorb water vapor and gases from the air. However, when it reaches the ground, the roots into the soil and serves to absorb water and mineral salts. Plants that have roots hanging for instance a banyan.
• Breath roots. Breathing roots growing out of the trunk bottom. The root of the majority appear on the soil surface and partly in the soil. This looks like a prop roots upright stems. Roots of breath has many gaps where the entry of air. So, as the name implies, serves breath roots to breathe. Plants that have roots of breath, such as mangroves and rushes.
• Adhesive roots. The adhesive grow roots along the stem. The adhesive contained in the roots of plants that grow climbing. This root is used to attach the rod on the wall as well as other plants. Plants that have roots adhesive, for example betel.

Root function
Root function for the plant:

• To support and strengthen the establishment of plants in the life
• To absorb water and mineral salts (substances of nutrients) of the soil
• Transports water and nutrients that have been absorbed into places on the body of plants that require saint
• In some kinds of plants there that serves as a means of respiration, eg mangroves
• In some species, there are useful as a place to store reserves of food or as a means of vegetative reproduction. For example, carrots have the enlarged taproot, serves as a place to store food. In the breadfruit plants, from the roots can grow buds that will grow into a new individual.

Modification of roots

• Roots breath. Roots up on the ground, especially on the water, such as the mangrove genera (Avicennia, Soneratia).
• Hanging roots. Roots entirely above ground. Hanging roots of epiphytic orchids found in plants.
• Root buttresses. This root is found in many types of tropical plants.
• Root suckers. These roots are the kinds of parasitic plants such as mistletoe.

Root pseudo
Organ or tissue that are anatomically can not be considered as roots but has a function similar to the root of the root called pseudo or Rhizoid (Ex. Rhizoid). The term is usually pinned on individuals who are not included vascular plant but can be attached to a particular object using a tool similar to the root function, namely to attach, anchor, or absorb nutrients from where he grew up. Gametophyte phase of algae and mosses and ferns have Rhizoid. Some herbs pterofit (Euphyllophyta) also has Rhizoid which is a modified leaf or stem. An example is the Azolla and Salvinia, and Lemna.
