Question

write difference between tap root system and fibrous root system​

Answer 1

Answer:

The main root (primary root) with other minor side roots, which grow deep into the soil is called Taproot. While the fine, thick hairs like structure, that spread sideways in all the directions is called Fibrous or Adventitious root.

Answer 2

Answer:

                                        TAP ROOT:

• Such roots which develop into primary root arising from radicle (embryonic root) , these become the main root of the plant , with secondary,tertiary and other lateral branches.

• It develops from the radicle of the embryo.
• consists of a persistent primary root.
• these are deep-rooted .
• always underground.
• it consists of only one long and main long.
• it can be the surface feeder or deep feeder.
• as compared to other roots is very thick.
• primary,secondary,tertiary and rootlets are visible.
• can survive in the drought area.
• this systems occur in dicot plants .
• leaves have reticulate venation.
• example: carrot , raddish, beets........

                                     FIBROUS ROOT:

• Such roots that arise from other parts of the plant like stems,or leaves other than roots are called fibrous root.
• it develops from the stem , leaves or places other than radicle.
• consists of the short-lived root.
• usually shallow.
• can be either underground or aerial.
• multiple root systems.
• the root system of this type is the surface feeder.
• roots are thin,hair like,similar in thickness and are in the form of the cluster.
• no differentiation in roots and bunch of roots develops at one spot.
• cannot survive in drought and will dry out easily,but quick in absorbing surface and irrigation water.
• this root system occurs in monocots.
• leaves have parallel venation.
• example: onion,grass,wheat,coconut palm......
