Explanation:

liverworts :-

  1. the gametophytic body may be thallose or foliose.
  2. on ventral surface of the thallus unicellular rhizoids and simple milticellular scales are present.
  3. sex organs are present on the dorsal surface of the thallus and develop from superficial cells.
  4. ealters are generally present but absent on riccia.
  5. stomata and chlorophyll are absent in the wall of the capsule of sporophyte.
  6. dehiscence of capsule is irregular.
  7. examples:-riccia and marchantia

mosses :-

  1. the gametophytic plant body  is differentiated into prostrate, branched filamentous, thalliod protonema and leafy erect gametophyte.
  2. rhizoids are multicellular, branched with opaque septa.
  3. sex organs develop from superficial cells at the apex of leafy gametophyte..
  4. elaters are absent.
  5. stomata and chlorophyll are are present in sporophyte for gaseous exchange.
  6. dehiscence of capsule is regular
  7. examples:-funaria

Answer:

Liverworts:

1. The plant body is dorsiventral.

2. The plants may be thallose or foliose

3. Leaves, when present, are without a midrib.

4. Branching is generally dichotomous.

5. Rhizoids are unicellular.

6. The plants may bear scales or amphigastria.

7. Sporogonium has little green tissue.

8. Seta develops rapidly towards the maturity of spores.

9. Capsule often possesses elaters.

10. Peristome teeth are absent.

11. Columella is generally absent.

12. A protonema stage is absent.

Mosses:

1. The plant body has a radial symmetry.

2. The plants are always leafy.

3. The leaves generally have a midrib.

4. Branching is lateral and extra-axillary.

5. Rhizoids are multicellular.

6. Scales or amphigastria are absent.

7. Sporogonium has a sufficient amount of green tissue to make it semi-independent.

8. Seta grows slowly over a long period and fully developed before the spores mature.

9. Elaters are absent.

10. Peristome teeth occur towards the apical region of the capsule.

11. Capsule contains a sterile columella.

12. A filamentous protonema occurs.
