Question

Which amongst the following options contains mismatched pair?

• A. direct elongation of radical -primary roots
• B. root system originating from the stem's base - fibrous roots
• C. roots not arising from the radical - stit roots
• D. constitution of primary root and its branches - tap root system
• E. All are correctly matched.

Answer 1

The correct option is E All are correctly matched.

• The primary root, or radicle, is the first organ to appear when a seed germinates. It grows downward into the soil, anchoring the seedling from the embryonic root (radicle), which grows out of the seed after the seed has absorbed water. This is the primary root of a new plant.
  
• A fibrous root system is the opposite of a taproot system. It is usually formed by thin, moderately branching roots growing from the stem
  
• Stilt roots are the adventitious roots that help in supporting the plant body. Also known as support roots. These roots develop from the basal nodes of the main stem.
  
• A taproot is a large, central, and dominant root from which other roots sprout laterally. Typically a taproot is somewhat straight and very thick, is tapering in shape, and grows directly downward. Taproot, the main root of a primary root system, growing vertically downward.
  

So. the correct answer is 'All are correctly matched'.
