What
are Thallophyta?
The term “Thallophyta” is derived from the Greek word
i.e., thallus means young shoot; phyta refers to plant. The plant under
this division are primitive exhibiting thalloid plant body i.e., not
differentiated into stem, leaves and roots. The term thallophyta was first
introduced by Stephan Endlicher in 1836.
Thallophyta
is the compilation of a wide variety of plants ranging from unicellular to
multicellular with simple mode of reproduction. This group mainly includes
members of Algae and Fungi.
Algae
are autotrophic in nature comprising a range of pigments including chlorophyll.
These plants mainly grow in water or in moist condition eg., Nostoc sp, Chara sp, Vaucheria sp, Diatoms,
Polsiphonia sp.
Whereas members in fungal group are heterotrophic
due to the absence of chlorophyll pigment. So for their survival they either
live as a saprophyte, parasite or in symbiotic relation with the host species.
Examples includes species of Alternaria,
Saccharomyces, Ascobolus, Agaricus etc
