| Tap Root |
Definitely, root is not something that is unfamiliar to you. Generally, root can be found underground, except for aquatic plant, parasitic plant, and epifit plant. According to the characteristic, there are two types of root system, tap root and fibrous root.
Tap root has a main root from which an advance development of radicle (primary root/embryonic root) occurs. Basically, main root grows more dominant and bigger than the main root produces branch root (secondary root/lateral root). The main root and the branch root support the erection of the pant system. This root system is found in dicotyledon.

| Fibrous Root |
Fibrous root has a main root that is not well developed and finally will dissapear. The root that continuesto develop is called adventitious root which emerges from the stem. It can be found around the node of stem with relative similar size and tightly arranged. Therefore, fibrous roots are strong enough to support the stem eventhrough it has shallow root. Fibrous root system is found in monocotyledon.
1. Structure of Root
The stricture of root is different from that of stem. There are no node and bud on root. As a result, root cannot produce shoot, except on some plants, such as talok (Muntingia colabora), sukun (Arthocarpus communis), and pine(Pinus mercusii).
The external structure (morphology) of root is composed of primary root, secondary root, root hair, root tip, and root cap.
The root tip is the youngest part and very delicate, whose cells are continuosly dividing and growing. A few milimeter from the root tip, there are root hairs. Root tip is protected by root cap (calyptra).
Internal root structure (anatomy) can be observed on monocotyledon and dicotyledon.
2. Function of Root
Root is necessary to support the pant erection. The parts that play the role are the main root (primary root) and the branch root (secondary root). In addition, root also functions in water and mineral salt (nutrient) absorption from soil. The water and nutrient will be used in photosynthesis.
How can young root tip penetrate into hard soil? The fact is that the root tip has protection tissue known as root cap (calyptra) that is necessary to protect root from mechanical injury as they push through the soil.
