Answer:
Correct Answer: A
Solution:
[a] The characteristic traits of the plant body of bryophytes is that the plant body of bryophytes is more differentiated than that of algae.
Difference between bryophytes and algae- (i) Tissue differentiation is well-developed in bryophytes while in algae it is found only in higher forms. (ii) Anisogamous, isogamous, and oogamous types of sexual reproduction occur in algae, while only oogamous type of sexual reproduction is present in bryophytes.
(iii) Sex organs in bryophytes are covered by a sterile jacket while in algae they are not covered.
(iv) Female sex organ in bryophytes is archegonium, while it is oogonium in algae. (v) In bryophytes, sporophyte is dependent upon gametophyte and in algae sporophyte is independent of gametophyte.
(vi) Embryo is present in bryophytes and absent in algae.
(vii) Sporophyte in bryophytes is differentiated into foot, seta and capsule.
