Air plants on other planets?

What would plant life on other planets be like?

How would alien plants survive, grown, bloom and germinate without Earth like soil, atmosphere, conditions? What about ecosystems?

Could bromeliads provide one possibility for extraterrestrial air plants?

bromeliads as observed in an electric grid near Carambeí, Paraná, Brazil. Bromeliads (Tillandsia recurvata) are aerial plants known for not requiring soil to fulfill their life cycle. Modified hairs on the surface of their leaves, called trichomes, help this odd plant to survive by filtering water and other nutrients from the ambient air and airborne dust. Moreover, trichomes reduce the effects of solar exposure and prevent bromeliads from losing water. In drier environments Tillandsia species open their stomata, which further reduces the amount of water loss.

Bromeliads bloom only once during their lifetime. Seeds of Tillandsia are extremely light and can easily fly long distances. When they settle in yarns they're still able to germinate. However, there's a high mortality rate and low growth rate in these harsh environments. Because bromeliads pick up trace amounts of toxins in the atmosphere, they're sometimes used in atmospheric biomonitoring.

Meat and drink for extraterrestrial life

Aerial plants might capture and grow using nutrients, chemical elements from the atmosphere. Could they use electromagnetic energy from the plasmaspheres and different layers?

How would extraterrestrial plant life grow or evolve on water and electrically planet Earth? And electromagnetic transformation of lifeforms.

The leaf bases of some bromeliads, like the giant airplant (T. utriculata), catch and hold water as a way of dealing with dry conditions. These tank bromeliads provide a nearly continuous water source that is used by a wide range of animals...

Some of the other bromeliads in the park don't hold water but have leaf bases that form a hollow chamber. These chambers provide a favorite home for acrobat ants (Crematogaster sp.). It is thought that the bromeliad gets nutrients from the ant waste in exchange for providing the ants with shelter.
