Difference between algae and bryophyte is:
1 terrestrial habitat
2 sterile jacket
3 biflagellate gametes
4 none of these
Explanation:
The main difference between algae and bryophytes is the division of plant body. No division of observed in algae whereas the plan body of bryophytes internally divided into photosynthetic and storage zone and in bryophytes sex organs are always multicellular and protected by a jacket of sterile vegetative cells. But in the sex organ of algae are single celled without a jacket of sterile vegetative cells.

The positive evidence of aquatic ancestory of bryophytes is:
1 peristomial teeth
2 ciliated sperms
3 chemotaxis
4 gametophytic plant body
Explanation:
Ciliated sperms are positive evidence for aquatic ancestry of bryophytes. Each sperm usually consist of minute, slender, spirally curved body or furnished with two long, terminal whiplash type flagella.

In Funaria, calyptra is derived from:
1 capsule
2 columella
3 antheridium
4 archegonium
Explanation:
In Funaria, calyptra is derived from archegonium. Funaria is a moss. They don't have a vascular system. Funaria fertilization is dependent on water for the transfer of sperm to the egg. The main plant body is gametophyte which is independent and the sporophyte is partially or fully dependent on gametophytic generation. It is commonly called rope moss or cord moss. The calyptra is protective envelop around the developing embryo. It is formed by the basal part of the archegonium.

Which of the following is not a case of epimorphosis?
1 Formation of sperms from small clumps of cells
2 Regeneration of tail in a lizard
3 Replacement of severed arm in starfish
4 Replacement of limp in salamander
Explanation:
The regeneration of the absent or disappeared, or disoriented tissues and organs through the process of redifferentiation of existing tissues or organs are termed as epimorphosis. Here, new growth is seen as in case of healing of wound, regeneration of lost parts, etc. The formation of sperms from small clumps cannot be a case of restorative regeneration or epimorphosis.

No division of observed in algae whereas the plan body of bryophytes internally divided into photosynthetic and storage zone and in bryophytes sex organs are always multicellular and protected by a jacket of sterile vegetative cells.
