Thallophyta ( plant kingdom ) , plantae: classification

Image
Thallophyta These are the plants with no body differentiation They do have a specific root, stem, leaves so they do not have specific differentiation   They prefer aquatic habitats examples :-green algae In thallophyta they have a hidden reproductive system -cryptogamae Algae They are autotrophic  Habitat :- Mostly aquatic (freshwater/ marine )  , found in most soil/ wood  Structure :- It can be unicellular,colonial, filamanteous  Examples :-volvox ( colonial ), Chlamydomonas (unicellular ), Ulothrix (filamenteous ), Spirogyra ( filamenteous ), Ulva, Cladophora (branched filaments) it is also known as river weed Algae reproduction  Asexual reproduction :- Fragmentation Parent organism will break into new pieces or multiple pieces on maturity, each of which give rise to a new individual. Example :- spirogyra when it  becomes matures it breaks into new pieces and each of these pieces are able to give rise to a ne...

Biological classification (kingdom protista)

Protista Characteristics Eukaryotes :-Specific membrane-bound cell organelles & distinct nucleus  They are mostly  unicellular i,e made of one cell Some are autotrophic, while other are heterotrophic They prefer moist and aquatic habitats They reproduce both sexually and asexually They are plant - like protists (algae)  They are animal like - protists(protozoa) They are fungus like -protists (slime moulds, water moulds ) Protists They are of  five types:- Chrysophytes Euglenoids Protozoans Dianoflagellates Slime moulds Chrysophytes They are also known as golden plants They are diatoms  plant- like protists They contain chlorophyll, carotene, & Xanthophylls Rigid cell wall made of pectin/cellulose/sillica Habitat:-  Aquatic Can be fresh water/ marine Float passively on water Mostly photosynthetic Diatoms: main producers of food in oceans  Store food as oil  Few are heterotrophic eating ...
