Quiz_Bryophyta 1. In Funaria, calyptra is derived from : Columella Antheridium Archegonium Capsule Explanation:The calyptra in Funaria is derived from the archegonium and serves as a protective cap for the developing sporophyte. 2. The teeth of peristome of Funaria are : Hygroscopic Sensitive Sensitive and hydrophobic Hydrophobic Explanation:The peristome teeth of Funaria are hygroscopic, meaning they respond to changes in humidity, which helps in the gradual release of spores. 3. The plants of Funaria grow : In pairs Solitary As saprophytes In aggregates Explanation:Funaria plants often grow in dense clusters or aggregates, which helps them retain moisture and provides a microenvironment conducive to growth and reproduction. 4. In Funaria : Male and female reproductive organs are on the same plant but on different branches Male and female reproductive organs are on different plants None of the above Male and female reproductive organs are on the same plant and on the same branch Explanation:In Funaria, male and female reproductive organs are found on the same plant but on different branches, allowing for close proximity for fertilization while preventing self-fertilization. 5. In bryophytes and pteridophytes, transport male gametes requires: Insects Wind Water Birds Explanation:Both bryophytes and pteridophytes rely on water to transport male gametes (sperm) to the female gametes (eggs). This is because their sperm are flagellated and require a film of water to swim through. 6. 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. 7. The plants which produce embryo but lack vascular tissue and seeds are placed in : Bryophyta Thallophyta Phanerogams Pteridophyta Explanation:Bryophyta includes plants that produce embryos but lack vascular tissue and seeds, distinguishing them from higher plants like ferns and seed plants. 8. 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. 9. Funaria are commonly found : On damp ground In water In sea As epiphytes Explanation:Funaria typically grows on damp ground where there is sufficient moisture to support its growth. This environment provides the necessary conditions for its reproductive cycle and overall development. 10. The middle sterile part of capsule is called: Columella Protonema Foot Spore sac Explanation:The columella is the central sterile tissue within the capsule of Funaria, which helps in the structural integrity and spore dispersal mechanism.
