thallophytes's Usage Examples:

In the Thallophytes the cytoplasm may be segmented by constriction, due to the in-growth of a new cell wall from the old one, as in Spirogyra and Cladophora, or by the formation of cleavage furrows in which the new cell-wall is secreted, as occurs in the formation of the spores in many Algae and Fungi.

Bacteria (see BACTERIOLOGY) and Cyanophyceae (see ALGAE), which are often grouped together as Schizophyta, are from points of view of both structure and reproduction extremely simple organisms, and stand apart from the remaining groups, which are presumed to have originated directly or indirectly from the Flagellatae, a group of unicellular aquatic organisms combining animal and plant characteristics which may be regarded as the starting-point of unicellular Thallophytes on the one hand and of the Protozoa on the other.

have been described, but, as has been said, " by far the Algae greater number of the supposed fossil Algae have no claim to be regarded as authentic records of this class of Thallophytes " (Seward, 1898).

In all plants, except Thallophytes, leaves are present at some period of their existence.

In plant cells its presence has been demonstrated in the Thallophytes and Bryophytes.

Cell Division.With the exception of a few plants among the Thallophytes, which consist of a single multinucleate cell, Caulerpa, Vaucheria, 'c., the division of the nucleus is followed by the division of the cell either at once, in uninucleate cells, or after a certain number of nuclear divisions, in multinucleate cells.

thallophytes's Meaning':

any of a group of cryptogamic organisms consisting principally of a thallus and thus showing no differentiation into stem and root and leaf
