In Pteridophytes, the main plant body is a: Sporophyte Gametophyte Prothallus Antheridium Gemmae are present in Pteridophytes Some Gymnosperms Some Liverworts Mosses Given below are two statements : One labelled as Assertion A and the other labelled as Reason R: Assertion A : The first stage of gametophyte in the life cycle of moss is protonema stage. Reason R : Protonema develops directly from spores produced in capsule. In the light of the above statements, choose the most appropriate answer from options given below: Both A and R are correct and R is the correct explanation of A Both A and R are correct but R is NOT the correct explanation of A A is correct but R is not correct A is not correct but R is correct Identify the pair of heterosporous pteridophytes among the following : Lycopodium and Selaginella Selaginella and Salvinia Psilotum and Salvinia Equisetum and Salvinia In bryophytes, the gemmae help in which one of the following? Gaseous exchange Sexual reproduction Asexual reproduction Nutrient absorption To which class of Pteridophytes does the 'Horse-tail' ( Equisetum ) belong? Sphenopsida Psilopsida Lycopsida Pteropsida To which of the following classes of Pteridophytes does the 'living fossil' Psilotum belong? Psilopsida Lycopsida Sphenopsida Pteropsida In certain liverworts like Marchantia , the structures that assist in the dispersal of spores by being hygroscopic are: Elaters Pseudo-elaters Gemmae Rhizoids Which of the following is a characteristic of the pteridophyte prothallus? It is a small, inconspicuous, multicellular, free-living, mostly photosynthetic thalloid gametophyte. It is a large, vascular, diploid structure that produces spores. It is a parasitic gametophyte that remains attached to the sporophyte. It is the dominant phase of the life cycle in all pteridophytes. Which of the following is responsible for peat formation? Sphagnum Marchantia Riccia Funaria Bryophytes are also known as 'Amphibians of the Plant Kingdom' because: They live in soil but depend on water for sexual reproduction They can live both in fresh water and marine water They have a vascular system like amphibians They occur only in aquatic habitats Moss peat is used as a packing material for sending flowers and live plants to distant places because- It is easily available It is hygroscopic It reduces transpiration It serves as a disinfectant The first terrestrial plants to possess vascular tissues ( xylem and phloem ) are: Pteridophytes Bryophytes Gymnosperms Angiosperms Which of the following bryophytes is used as packing material for trans-shipment of living material because of its water-holding capacity? Sphagnum Marchantia Funaria Polytrichum The sporophyte in mosses is more elaborate than that in liverworts and consists of three parts. Identify them: Foot, Seta, and Capsule Rhizoids, Stem, and Leaves Holdfast, Stipe, and Frond Root, Stem, and Strobilus Tall and slender cells with nuclei located at the base, commonly found lining the stomach and intestine to aid in secretion and absorption, are: Simple columnar epithelium Simple cuboidal epithelium Simple squamous epithelium Ciliated epithelium The inner wall of the frog's intestine has many finger-like folds called: Villi and microvilli Rugae Typhlosole Plicae circulares Ectophloic siphonostele is found in - Osmunda and Equisetum Adiantum and Cucurbitaceae Marsilea and Botrychium Dicksonia and Maiden hair fern In the prothallus of a vascular cryptogam, the antherozoids and eggs mature a different times. As a result there is high degree of sterility one can conclude that the plant is apomictic self-fertilization is prevented there is no change in success rate of fertilization Which one of the following is considered important in the development of seed habit ? Free-living gametophyte Dependent sporophyte Heterospory Haplontic life cycle 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) Gymnosperms (2) Liverworts (3) Mosses (4) Pteridophytes Given below are the stages in the life cycle of pteridophytes. Arrange the following stages in the correct sequence. A. Prothallus stage B. Meiosis in spore mother cells C. Fertilisation D. Formation of archegonia and antheridia in gametophyte. E. Transfer of antherozoids to the archegonia in presence of water. Choose the correct answer from the options given below: E, D, C, B, A B, A, D, E, C B, A, E, C, D D, E, C, A, B In a moss the sporophyte- is partially parasitic on the gametophyte produces gametes that given rise to the gametophyte Arises from a spore produced from the gametophyte Manufactures food for itself, as well as for the gametophyte The correct sequence of events in the life cycle of bryophytes is A. Fusion of antherozoid with egg. B. Attachment of gametophyte to substratum. C. Reduction division to produce haploid spores. D. Formation of sporophyte. E. Release of antherozoids into water. Choose the correct answer from the options given below : D, E, A, B, C D, E, A, C, B B, E, A, C, D B, E, A, D, C Which of the following is a precursor to the seed habit, often seen in heterosporous pteridophytes like Selaginella ? Retention of the female gametophyte on the parent sporophyte Development of a heart-shaped prothallus Formation of a thick-walled zygote Requirement of water for fertilization Sphenopsida class belongs to . bryophytes angiosperms gymnosperms pteridophytes Spore dissemination in some liverworts is aided by indusium calyptra peristome teeth elaters. Which one of the following is a vascular cryptogam ? Cedrus Equisetum Ginkgo Marchantia Which one of the following is responsible for peat formation ? Marchanita Riccia Funaria Sphagnum In bryophytes and pteridophytes, transport of male gametes requires :- (1) Wind (2) Insects (3) Birds (4) Water Strobili or cones are found in Pteris Marchantia Equisetum Salvinia Genera like Selaginella and Salvinia produce two kinds of spores. Such plants are known as: Heterosorus Homosporous Heterosporous Homosorus
