How is a tap root different from fibrous root
Answers
Explanation:
what is taproot?
A taproot is when there is one main root that grows straight down deep into the soil. It only has very few lateral roots that develop and grow off this main root.
The taproot is a feature of plants that are known as dicotyledons and it is also found in the plants known as gymnosperms.
The taproot is further differentiation of the primary root. The primary root is formed from the radicle of the seedling during development of the seed.
In the taproot system the main root is the largest and longest, and lateral roots are smaller and shorter. A few side roots that are known as lateral roots form from the main root.
A taproot penetrates deep into the soil and in some cases can form a storage organ for food, for instance: carrots, radish, beetroot and turnips.
Advantages of a taproot include the fact that they do penetrate deep into the soil and so can locate water and minerals deep underground, the mesquite plant for instance has roots that can penetrate up to 150 ft. deep in search of water. It is thus very drought tolerant.

The taproot is also good at anchoring the plant into the soil so preventing them from being blown over in windy environments.
Certain weeds such as Dandelion are difficult to pull out because of the taproot.
A further advantage is that they can form, in some cases, storage organs, storing food such as starch or sugars, for the plant.

What is Fibrous root?
A fibrous root is a root that consists of groups of roots of similar size and length. They do not penetrate as deeply into the soil as does a taproot.
The fibrous root is a feature of plants that are monocotyledons. Unlike the tap root, the primary root produced during development does not remain, and instead roots, known as adventitious roots, are produced from the stem of the plant.
All these roots forming the fibrous root collectively are of equal size and length.
A fibrous root system does not penetrate deeply into the soil but rather creates a thick network of roots that are good at holding the soil together.
Many types of grasses have fibrous roots, including plants related to grass such as corn.
Advantages of fibrous root systems include that they allow the plant to absorb water and minerals over a large surface area closer to the surface of the soil.
Answer
A tap root system has a single main root that grows down. A fibrous root system forms a dense network of roots that is closer to the soil surface. An example of a tap root system is a carrot. Grasses such as wheat, rice, and corn are examples of fibrous root systems.
