Answer 1

Hint: Modification of roots in the plants take place to support the plants, help in storage of food and respiration. The given modification in the questions are for storage of food in the plants.

Complete answer:
Option A- will be the correct answer because the first column matches correctly with the second column.

Conical roots of Daucus carota helps to store food produced by the plants during photosynthesis. Tuberous roots also help in storing food which can perennate the roots during dry and cold periods. Fusiform roots are the roots that taper at the end and swollen at the middle.

Let us see why other options are incorrect-
Option B- the given matchings of first and second column are incorrect.
Option C- the given matchings are incorrect.
Option D- the given matchings of the first and second column are incorrect.

Hence, the correct answer is option (A)

Note: Roots provide strength to the plants to grow and divide. They are differentiated into prop root and stilt root. Stilt roots are adventitious roots which grow at an angle and help in the growth of the plant by supporting the roots. Prop roots grow from other parts of the plants to support strength to that part of the plant. Roots also provide storage of food which are later used by the plants. Roots like conical, moliform, tuberous, fusiform, napiform help in the storage of food in them. They store reserve food in them.
