Grass first appeared about 67 million years ago, 2 million years before the dinosaurs died out. The first fossil traces of it were found in fossilized dinosaur dung that dated to about that time.
It generally takes a few days to a couple of weeks for the first leaves to appear after a seed germinates, depending on the plant species. Some plants may take longer to develop leaves while others may sprout leaves within a few days.

The gametophyte generation is more prominent and independent in mosses and ferns compared to seed plants. Also, the sporophyte generation in mosses and ferns is not as prominent or long-lived as in seed plants. Finally, mosses and ferns rely on water for fertilization, a characteristic not seen in seed plants.
About 250,000 species of seed bearing plants
Only seeds have seed coats not plants. Not all seeds have seed coats.

There are three structures that appear from the seed: the radical, the hypocotyls and the plumule. The first structure to appear from the seed is the radical, which is the root and grows downward into the soil.
A cotyledon is a seed leaf found in the embryo of a plant. It is the first leaf or pair of leaves that emerge from a seed upon germination. Cotyledons are essential for providing nutrients to the growing plant until it can photosynthesize on its own.
Non-seed plants evolved from seed plants.
