Choose the incorrect statement among the following:
1 A, B only
2 B, D only
3 A, C only
4 B, C only
Explanation:
(A) Pteridology is the study of pteridophytes. Pteridophytes have well developed tissue system and so these are higher cryptogams or vascular cryptogams. (B) Palynology is the study of pollen grains. (C) Biophysics and molecular biology are pertinent to both plant and animal science. (D) Tissue culture is the technique of growing cells and tissue in an artificial medium separated from the organism. This technique is also called as micropropagation. It produce disease free plants in large number by meristem tip culture.

Following is not a common feature in both ferns and Gymnosperms
1 Presence of Archegonia
2 Circinate vernation
3 Presence of ramenta
4 Presence of ovules
Explanation:
Presence of ovules is not a common feature in both ferns and gymnosperms. Ferns are plants that do not bear flowers and do not have any seeds as well. While gymnosperms have seeds, although seeds are not put inside an ovary.

From evolutionary point of view, retention of the female gametophyte with developing young embryo on the parent sporophyte for some time, is first observed in
1 Mosses
2 Pteridophytes
3 Gymnosperms
4 Liverworts
Explanation:
Pteridophytes are considered as the first plants to be evolved on land. They are cryptogams, seedless and contain vascular tissue but lack xylem vessels and phloem companion cells. - In pteridophytes, megaspore is retained for a significant amount of time within female gametophyte on the parent sporophyte, however the permanent retention of seed is seen in Gymnosperm. Thus, pteridophytes exhibit precursor to seed habit.

Pteriodophytes, especially ferns possess the following characteristics (i) Circinate vernation (iii) Eustele (ii) Ramenta (iv) Paraphyses Options:
1 iii \& iv
2 i \& ii
3 i, ii \& iv
4 ii, iii \& iv
Explanation:
Circinate arrangement of young leaves \& the presence of ramenta are charcteristic feature of ferns. - Eustele is a type of stele found in mostly seeded plant. It is a type of siphonostele in which the vascular bundles are arranged in a ring pith surrounded primary vascular tissue. - Paraphysis is a sterile hair like filament present among the reproductive organs in many lower plants, especially Broyphytes, Algae \& Fungi.
