Selaginella possess small leaves called Microphylls, while ferns possess large leaves called Macrophylls. Cones and strobili are seen in Equisetum. Salvinia is Heterosporous as they produce two kinds of spores.
14.)
Solution:c) Microphyllous
Leaves with complex series of veins and formation of leaf gap takes place then it is referred to as Macrophyllous. No leaf gap formation and presence of one vein in leaves are known as Microphyllous
15.
Solution:(d) They do not possess xylem and phloem
Pteridophytes are the first terrestrial plants to possess vascular tissues i.e. xylem and phloem.

17.)
Solution:(a) Prothallus
A photosynthetic thalloid gametophyte called Prothallus is formed by the germination of spores.

Solution:b) Sporocarps
Salvinia have sporangia within specialized structure. Within specialized structure, when sporangia are present in aquatic forms then it is Sporocarps.
19.)
Solution:(d) Selaginella
Selaginella is not an example of the class Pteropsida.
20.)
Solution:d) Male microspore
Two types of spores and sporangia are present in the Heterosporous where one is small and other is large. So, microsporangia produces male microspore.
21.)
Solution:(b) Water
The transfer of antherozoids released from antheridia to the mouth of archegonium takes place by the means of water.
22.)
Solution:b) Only iii)
A sterile jacket surrounds Antheridium, Hence, iii) is the right pair.
23.)
Solution:(a) Archegonium
In pteridophytes, the egg is present in the archegonium.
24.)
Solution:a) Antherozoids
Antheridia are sessile and Antheridium is surrounded by single layered jacket. Antherozoids have two apical flagella which are spirally coiled.

Solution:(a) Female
Megaspores germinates and gives rise to female gametophyte.
26.)
Solution:d) Fertilization
In the Pteridophytes, water is essential for the movement of sperms. Hence, essential for fertilization as well.
27.)
Solution:(c) The sporophyte bears the male and female sex organs
In the pteridophytes, the gametophyte bears the male and female sex organs.
28.)
Solution:b) Small sessile leaves
Leaf-like scale are scale leaves, large petiolate are large leaves. Small leaves with no leaf stack are small sessile leaves.
