There are numerous types of plants roots and they are connected differently in every species of a plant. This is often referred to as the root system. The root system differs from one plan to another. The root system is also responsible for the growth of the plant, the immune system of the plant and productivity of seed, flower or a vegetable. Continue to read ahead as we provide complete information related to the different types of plants roots.
1. Taproot system
Radical is the name given to the first two route produced from a seed. This route greatly enlarges over a period and becomes the prominent root of the plant. Smaller branches grow from the taproot and spread largely in area.
2. Fibrous root system
In certain species of plants, the taproot system is short lived and is replaced by numerous routes. The presence of these numerous roots is referred to as adventitious as they have the ability to grow from any plant organ.
3. Aerial roots
Aerial roots types of plants roots grow downward from the tropical tree canopy. They are extremely long and appear as an unbranched root. They are exposed to air and often appear on the ground.
4. Buttress or tabular roots
Tabular roots are vertically flattened and project out of the ground. They are often found at the base of large trees. Presence of this tabular roots increases tensile force, which resists uprooting of the tree.
5. Contractile roots
Contractile roots have a short life in terms of their length. The shrink and length over a period and draw part of a plant towards the soil. The best example for such species of plants can be found among bulbous plants.
Such roots are often present in waterlogged soils. It becomes difficult for a plant to grow, as the root system does not find enough oxygen to maintain healthy tissues. These roots are often termed as breathing roots. They have special air channels that exchange gas with the atmosphere. This makes it easy for the root to obtain the necessary oxygen for the entire root system, which is submerged in water.
These types of plants roots are fused with the stem of the plant. Such species of plants are often available in fire prone habitats. They use a specific strategy to recover from fire or dormancy. The root system is seasonal and appears in dry atmosphere.
8. Haustorial root
These types of plants roots are found in specific parasitic plants. The root system becomes cemented to the host via a sticky attachment disc. The sinker of the parasitic plant intrudes into the tissues of the host to roots.
9. Strangling roots
Strangling roots are primary hemi epiphytes that begin their life as tropical epiphytes. After a specific period, they develop adventitious roots that reach and root into the soil. These adventitious roots surround the trunk of the tree and eventually kill the host tree by strangling the bark. Such a root system is rarely found in the general plantation.
