Question

Orchids are a recently evolved plant that have a novel feature known as aerial roots. What is the most likely function of an orchid's specialized roots?
Aerial roots are the site of energy synthesis.
Aerial roots allow the orchid to attach itself to trees.
Aerial roots produce food for the orchid through photosynthesis.
Aerial roots anchor the orchid to the ground.

Answer 1

Aerial roots allow the orchid to attach itself to trees.

Explanation: Many orchids are epiphytes (grow on other plants). Their aerial roots anchor them to tree branches and absorb moisture and nutrients from the air and rain — they are not primarily ground anchors or the main site of energy synthesis (leaves perform most photosynthesis).
