Quiz_Bryophyta 1. In moss, conducting tissue is made up of Sclerenchyma Elongated parenchymatous cells Xylem and phloem Xylem Explanation:In mosses, the conducting tissue is made up of elongated parenchymatous cells, which help in the transport of water and nutrients. 2. In moss, peristomial teeth are: 16+32 16+16) 8+8 16+8 Explanation:The peristome of mosses typically consists of 16 pairs of teeth, making a total of 32. These teeth aid in the dispersal of spores by responding to humidity changes. 3. Bryophyta have a special character from other plants: They do not have vascular tissue They form spores Their sporophyte is dependent upon gametophyte They do not have roots Explanation:In bryophytes, the sporophyte is physically and nutritionally dependent on the gametophyte. This is a distinctive characteristic that sets them apart from other plant groups where the sporophyte is typically independent. 4. The gametophyte produced by apospory is : Diploid Haploid Triploid Parthenogenetic Explanation:The gametophyte produced by apospory is diploid because it arises from the sporophyte tissue, which is diploid, rather than from haploid spores. 5. The antheridia in Funaria are formed at the apex of the male shoot in : As solitary organs Groups of two Groups of many Groups of three Explanation:The antheridia of Funaria are formed in groups of many at the apex of the male shoot, which aids in the efficient release of sperm cells for fertilization. 6. In between the sex organs of Funaria are found a number of hair-like structures which are known as : Paraphysis Apophysis None of these Cleistothecium Explanation:Paraphysis are hair-like structures found between the sex organs in Funaria, providing support and protection to the reproductive organs. 7. The columella of moss is the region of moss capsule : Reproductive Sterile Sterile or fertile Fertile Explanation:The columella in moss capsules is a sterile structure that supports the spore-producing tissues and aids in spore dispersal. 8. The spores of Funaria on germination give rise to : Primary protonema Protonema None of the above Secondary protonema Explanation:The spores of Funaria germinate to form a primary protonema, which is the initial stage of the gametophyte generation. 9. The leaves of Funaria are : Stalked Sessile None of these Petiolate Explanation:The leaves of Funaria are sessile, meaning they are directly attached to the stem without a petiole. 10. In moss, sporophyte is formed on: Archegoniophore Antheridiophore Carpophore Gynophore Explanation:In mosses, the sporophyte develops from the fertilized egg within the archegonium, which is situated on the archegoniophore. This structure supports the female reproductive organs. Loading …
