Identify the wrong statement in relation to Funaria
1 Stomata are present in the epidermis of capsule
2 Spores are viable for only one year
3 Inner spore sac is one celled in thickness
4 Trabeculae connect the innermost layer of the capsule wall with the outer spore sac
Explanation:
Spores of funaria hygrometrica have been reported to remain viable up to 9 years. In the present study spores were found to remain viable for 11 years. Funaria belongs to the family Funariaceae. It comprises of the cord mosses and being characterised by filamentous setae, a gibbous obtusely pyriform capsules and usually a double peristome of 16 teeth.

Which one is pioneer in gametophyte generation of bryophytes?
1 Spore (n)
2 Protonema
3 Sporogonium
4 Spore mother cell
Explanation:
: Spore is the $1^{\text {st }}$ cell of the gametophytic generation. Spores are produced as a direct result of meiosis. - These haploid pioneer structure of gametophytic generation are formed from spore mother cell by meiosis which in turn are produce within sporangium.

Mosses occurs in moist places because
1 They can not grow on land
2 Their gametes fuse in water
3 They lack vascular tissue
4 They lack root and stomata
Explanation:
The reproduction in mosses takes place in water, thus they occur in moist place. As fertilization takes place only in the presence of water, through motile antherozoids that swim to reach the archegonium. They are also called as amphibians of plant kingdom due to dependence on water.

In ferns and mosses, movement of antherozoids towards female component is called :
1 phtotaxis
2 chemotaxis
3 hydrotropism
4 thigmotropism
Explanation:
In fern and mosses (Bryophytes), movements of antherozoids towards female component archegonium is stimulated by a special chemical like sugar called chemotaxis movement.

In which of the following pairs of genera sporocarps are present ?
1 Marsilea and Salvinia
2 Marsilea and Isoetes
3 Isoetes and Salvinia
4 Marsilea and Lycopodium
Explanation:
The sporocarp develops when plant becomes mature in aquatic species water evaporate and they develop in shallow water but in terrestrial species they are developed when water completely dries. The primary function of sporocarp is the production and release of spores. The sporocarpars are present in the genera Marsilia and Salvinia.
