Answer 1

Answer: (A), (D), (E), (G)

coralloid roots

Gymnosperms generally have a taproot system. In some gymnosperms like the Pinus, they have fungal hyphae growing symbiotically within the roots forming Mycorrhiza. This helps the trees to absorb nutrients efficiently.
Roots of the trees belonging to the genus Cycas are adventitious and have a symbiotic association with nitrogen-fixing Cyanobacteria. These roots are called coralloid.
