There are multiple major evolutionary changes throughout the phylogeny, as you move from bacteria/archaea all the way to lillum and tillia.
You can see the gametophyte dominance being displayed in the more primitive plants, such as the moss depicted on the cladogram.
An evolutionary change shows the emergence of sporophyte dominance in plants such as conifers, like the ovulate cone and staminate cone observed in lab.
The evolvement of vascular tissue is also prominent – which consists of xylem and phloem, allowing the plant transport of water and nutrients, and can be further away from a source of water compared to nonvascular plants.
Nonvascular plants, like bryophytes, would be found in more moist environments. Another majorevolutionary change would be no seeds to seeds, where many important benefits come with it, including protection and nutrition for the embryo,
