Thallophyte

Lichens are some of the organisms included in several definitions of the Thallophyte group.

Thallophytes (Thallophyta, Thallophyto or Thallobionta) are a

Phanerogamae. Thallophytes are defined by having undifferentiated bodies (thalloid, pseudotissue), as opposed to cormophytes
(Cormophyta) with roots and stems. Various groups of thallophytes are major contributors to marine ecosystems.

Definitions

Several different definitions of the group have been used.

Thallophytes (Thallophyta or Thallobionta) are a polyphyletic group of non-mobile organisms traditionally described as "thalloid plants", "relatively simple plants" or "

lower plants
".
Embryophyta in this case) in 1836.[1][2] This definition of Thallophyta is approximately equivalent to Protophyta, which has always been a loosely defined group.[3]

Thallophyta is a division of the plant kingdom including primitive forms of plant life showing a simple plant body. Including unicellular to large algae, fungi, lichens.[5]

The first ten phyla are referred to as thallophytes. They are simple plants without roots stems or leaves.[6]

They are non-embryophyta. These plants grow mainly in water.

Subdivisions

The Thallophyta have been divided into two subdivisions:[7]

  • Myxothallophyta (myxomycetes)
  • Euthallophyta (bacteria, fungi, lichens, algae)

The term Euthallophyta was originally used by Adolf Engler.[8]
