Why do merchandants put air in the bags when you buy plants?

Question

I bought a plant from a nursery and they put air in the bag before it was sold to me.

Answer 1

They do this to keep the bag from doing physical damage to the plant, by collapsing inward on the delicate petals. Also, a cushion of air is a good insulator from extreme temperatures if you leave the bag in the hot sun.

Answer 2

To protect the plants from getting damaged on the trip home. I hope this helps.
