It is said that there is no embryo formation in thallophyta. What does it mean? Does it mean that they remain unicellular?

In all nonvascular plants, the gametophyte generation is dominant. Sporophytes grow from these gametophytes and need them as they provide them with the nutrients and water they need to survive. Non-vascular plants lack xylem and phloem which are part of the conducting tissue in higher plants. These tissues transport food and oxygen throughout a vascular plant. These are among the simplest of plants with no roots, stems, or leaves, just a thallus. They also don't possess flowers, a sexual reproductive organ found in higher plants. However, thallophytes are usually multicellular organisms as seen in mosses and liverworts, for example.
