GENERAL CHARACTERS OF BRYOPHYTES

2. GENERAL CHARACTERS OF
BRYOPHYTES

3. Bryophytes are an informal group consisting of
three divisions of non-vascular land plants.
 Liverworts
 Hornworts
 Mosses
The bryophytes consist of 20000 species.
Bryophytes produce enclosed reproductive
structures (gametangia and sporangia),but they
do not produce flowers or seeds. The term
“bryophytes” comes from Greek Bryon “tree
moss oyster- green” + phyton “plant”.

4.  Bryophytes are non-vascular plants.
 They have no conducting and strengthening
tissues(xylem and phloem).
 They were evolved from green algae.
 They are poorly adapted for life on land.
 They are present only in damp shady places.
 The transport of water,minerals,prepared food
and substances take place by diffusion.
 They do not have proper roots but have
rhizoids.

5.  They can reproduce by means of spores.
 Bryophytes are called amphibians of plant
kingdom.
 These plants can live in soil but are dependent
on water for sexual reproduction.
 The plant body is without cuticle.
 Water is absorbed by the general surface of the
plants.
 In bryophytes gametophyte
is dominant and sporophyte
is attached to it.

6.  Sex organs in bryophytes are ANTHERIDIA
and ARCHEGONIA.
 Bryophytes show alternation of generation.
 In these plants sporophyte is diploid(2n).
 Sporophyte consist of foot, seta and capsule.
 Sporophyte of bryophytes is homosporous.

7.  Gametophyte of bryophytes is haploid.
 It consist of leaves and rhizoids.
