Embryophytes are land plants. They are the most familiar kinds of plants, the bryophytes, ferns, gymnosperms and flowering plants. Only a few embryophytes are water plants. They don't include the algae.
The embryo is defined as an immature sporophyte that is attached to or surrounded by the gametophyte. In many land plants, such as the seed plants, the embryo will remain dormant for a period of time and will begin growth only after the proper environmental conditions are met.
The classification “embryophytes” refers to the evolution of the embryo, a zygote that is retained and nourished by the female gametophyte as it grows.
Oct 31, 2023 · Land plants, or embryophytes, are classified by the presence or absence of vascular tissue and how they reproduce (with or without seeds). Learning Objectives. Identify the major divisions of land plants. Key Points.
Evidence of the emergence of embryophyte land plants first occurs in the middle Ordovician (~ 470 million years ago ), and by the middle of the Devonian (~ 390 million years ago ), many of the features recognised in land plants today were present, including roots and leaves.
