Question

give the classification of thallus​

Answer 1

Explanation:

In this article we will discuss about the thallus organisation found in algae.

The plant body in algae is always a thallus. It is not differentiated in root, stem and leaves. Algae range in size from minute unicellular plants (less than 1 µ in diameter in some planktons) to very large highly differentiated multicellular forms e.g., some sea-weeds.

Their forms may be colonial (loose or integrated by inter-connections of protoplasmic strands), filamentous (branched or un-branched), septate (branched or un-branched), non-septate or branched, multinucleate siphonaceous tube where the nuclear divisions occur without usual septa

Thalli include uniseriate, unbranched (eg, Chaetomorpha) or branched filaments (eg, Cladophora) with multinucleate cells in the order Cladophorales, or blades that are monostromatic (eg, Monostroma and Gayralia in the order Ulotrichales) or distromatic (eg, Ulva in the order Ulvales) and have uninucleate cells.
