Match the plant parts of gymnosperms in List I with their characteristic features in List II. List I List II A. Pinus roots I. Coralloid roots B. Cycas roots II. Unbranched C. Pinus stem III. Mycorrhiza D. Cycas stem IV. Branched Choose the correct answer from the options given below:

Step-by-step solution

In gymnosperms, different genera exhibit distinct morphological features. Roots: Pinus has a symbiotic fungal association in the form of mycorrhiza. Cycas has small specialised roots called coralloid roots that associate with nitrogen-fixing cyanobacteria. Stems: The stems are branched in Pinus and Cedrus, whereas they are unbranched in Cycas. Therefore, the correct match is A-III, B-I, C-IV, D-II. Answer: A-III, B-I, C-IV, D-II
