Answer 1

$\boxed{\boxed{Answer:-}}$

Division : Thallophyta -

Members are mostly aquatic, few grow on other plants as epiphytes. Some grow symbiotically and epizoic i.e. growing or living non-parasitically on the exterior of living organisms. Aquatic algae grow in marine or fresh water. Most of them are free living while some are symbiotic. Plant body is thalloid i.e. undifferentiated into root, stem and leaves. They may be small, unicellular, microscopic like Chlorella (non- motile), Chlamydomonas (motile). They can be multicellular, unbranched, filamentous like Spirogyra or branched, filamentous like Chara. Sargassum, a huge macroscopic sea weed which measures more than 60 meters in length is also an alga.

Answer:

The division Thallophyta is classified into two sub-divisions: 1) Algae---> They are chlorophyll-bearing thalloid, autotrophic and largely autotrophic and largely aquatic (freshwater and marine water) plants. Example: Spirogyra. 2) Fungi--->They are achlorophyllous (non-green) heterotrophic thallophytes.
