The nutrition of some plants is enhanced by a mutually beneficial interaction between a root and soil bacteria. The interaction triggers formation of a _______.

  1. a. root nodule
  2. b. mycorrhiza
  3. c. root hair
  4. d. hypha

Summary Introduction

Introduction: Symbiotic relationship of plant with nitrogen-fixing bacteria forms root nodules on the roots. The bacteria help to convert atmospheric nitrogen into a readily utilizable form for plants. This process is called as nitrogen fixation. Fixed nitrogen acts as a nitrogen fertilizer that promotes plant growth.

Explanation

Reason for the correct answer: A mutual interaction between the plant and bacteria triggers the formation of root nodule. Plants provide nutrients to the bacteria and in turn it helps to fix nitrogen from the atmosphere. Leguminous plants release certain compounds called as flavonoids from the roots, which triggers the nodule formation in the roots.

Option a. is given as, “root nodule”. Symbiotic interaction between the plant and bacteria triggers the nodule formation in plant roots.

Hence, option a. is correct.

Reasons for the incorrect answers:

Option b. is given as, “mycorrhiza”. This is incorrect. Mycorrhiza is a mutual relationship between a fungus and plant root...
