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...
Monera reproduction Asexual mode Sexual mode Asexual mode of reproduction Monera reproduces mostly through asexual mode of reproduction by fission, spore formation etc. Sexual mode of reproduction
Bryophyta Mosses Characteristics:- They mostly prefer moist and shady habitats Their plant body is simple: They don't produce their own seeds or flowers, They have simple leaves which is covered with thin stems, They have root-like structures, Rhizoids Like liverworts, the gametophyte is the predominant stage in the life cycle of mosses Gametophyte:- it consists of 2 stages Protenema It develops from a spore, They are green, creeping and branched structure Leafy stage (final gametophyte) It develops from secondary protonema, They have an upright axis with spirally arranged leaves Examples;- Funaria, Sphagnum, Common hair cap moss Reproduction:- Asexual reproduction Fragmentation:- Stems, leaves from the moss accidentally broken off can regenerate to form a new plant. Budding:- New individual is formed as an outgrowth of the parent, Daughter separates away and parent continues to exist Sexual reproducti...
