Explanation:

Orchids are epiphytes (plants that grow on other plants). Aerial roots help them attach to host trees (like branches). Energy synthesis (through photosynthesis) mainly occurs in leaves (not roots). Roots that anchor to the ground are typical root systems (not aerial). Aerial roots' main function here is attachment.

Answer:

Aerial roots allow the orchid to attach itself to trees.
