Question

importance of seeds to plant evolution?

Answer 1

Even though seeds aren't the earliest to hit the scene in plant evolution, as Djddan has stated, they have played a HUGE role in evolution...

The main thing is that seeds have given their parent plant an opportunity to travel! In general, plants are stationary organisms. Without means for locomotion (like most animals have), they must rely on their seeds to move for them. The reason is that it increases the area their genetic material can travel.

If seeds didn't travel, you would have huge pockets of areas that would have many genetically similar plants.



Seeds ensure travel many different ways. Some have wings on them so that the wind can carry them away from their parent tree. Some are embedded in tasty fruit thhat get carried off by hungary animals. Some stuck to animals walking by, some are dropped into water and carried off by flowing rivers...The list goes on.



Seeds have impacted evolution in huge ways. Hope this helps.

Answer 2

Spermatophytes seem to be the last to hit the scene. The angiosperms have the seeds but to me seeds seems unimportant to plant evolution. The mosses and ferns appeared much sooner than seed-bearing plants. Grasses spreading by their roots.
