what was the first plant on earth formed..?

Answer 1

Probably a distant relative of algae. Algae themselves are known from about 3 billion years ago. It would have been a simple single-celled organism in the "primordial soup" that was able to convert sunlight into energy using a chlorophyll-like molecule. Here's a brief simple little discussion of them:

Answer 2

Green algae colonies in the seas 1.4 billion years ago. An example of this would be green seaweed, a lot like kelp for practical purposes. Unless you don't consider seaweed the type of "plant" you were looking for, in which case for land plants that would be...about 480 million years ago. The first land plants being very primitive bryophytes or mosses and the like. There weren't vascular plants or angiosperms like trees or anything, not that far back. Can't give you an exact species name for the first land plant as of yet. I'll keep researching it and try to come up with a name for you.

Okay, a few tens of millions of years after that you get your first vascular plants, whisk ferns and their relatives, and around 300 million years ago you get conifers, those are like pine trees and spruces with all the needles, evergreens.

On a side note, did you know that there was no grass during the time of the dinosaurs? It was around yet. So grasses are under 64 million years old. Maybe you would find that interesting. There were bushes and leaves and fruits and so forth, just no grass.
