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...

Bryophyta (plant kingdom )

Image
Bryophyta Body differentiation exists:- They have stem-like and leaf-like structure  These are known as plant amphibians because even if they live in soil but they need water to complete their life cycle. water is something which is mandatory for them.  They are mostly found in moist hilly areas the specialized vascular tissue is  absent in them  They play a very significant role in preventing soil erosion They have hidden reproductive system-cryptogamae Example; Mosses, hornworts, liverworts Structure  Here body differentiation exists  They are erect with unicellular/ multicellular rhizoids (Rhizoids: -Hair-like structures from the lower epidermal cells  of bryophytes )  There are no true roots/stem/leaves  Reproduction Asexual reproduction:- They reproduce asexually through fragmentation Spore formation Sexual reproduction:- Gametophyte (plants which produce gametes ) Male gamete - Anthero...
