Question

Compare the characteristics of Thallophyta, bryophyta and Pteridophyta.

Answer 1

thallophyta - aquatic 
                 - among plants have simplest organisation they do not have well differentiate plant body .
                 -  the plants of this group are almost algae .
                 -  body type is thallus 
                 -  asexual reproduction 
    e.g. - ulva

bryophyta - they are called as amphibions of plant kingdom .
               - they have well differentiate plant body 
               - steam doesn't have specilized vascular tissue ( xylem & phyloem )
               - asexual & sexual reproduction
     e.g. - funaria
pteridophyta - they have differentiated plant body 
                   - specilized vascular tissue .
                   - they don't bare seeds 
            e.g. ferns 

Answer 2

thallophyta :- 
1: have no differentiated body parts
2: produce through asexual reproduction 
bryophyta :-
1: have differentiated body parts
2: have specialized vascular tissue system 
3: produce both through sexually or asexually .
pteridophyta :-
1: have differentiated body parts 
2: have specialized vascular tissue system 
3: don not bear seeds
