Students will be covered for all their studies as the topics are available from basics to even the most advanced. .

Q1.   Mosses occur in moist place because
  •  The cannot grow on land
  •  Their gamete fuses in water
  •  They lack vascular tissue
  •  They lack root and stomata
(b) The reproduction in mosses take place in water, thus they occur in moist places.

Q2.   Which of the following options correctly identifies the plants their groups from the following structure?

  •  A-Funaria-Moss; B-Sphagnum-Moss
  •  A-Funaria-Liverwort; B-Sphagnum-Moss
  •  A-Selaginella-Bryophytes; B-Funaria-Liverwort
  •  A-Selaginella-Pteridophytes; B-Funaria-Moss
(a) A-Funaria-Moss; B-Sphagnum-Moss

Q3.   A mature pollen grain of Pinus has
  •  2 cells
  •  3 cells
  •  4 cells
  •  5 cells
(c) In Pinus, the microspore nucleus divides by a periclinal wall and forms a very small prothallial cell and large central cell. The central cell cuts off a second prothallial cell and antheridial cell. The nucleus of the antheridial cell divides to form generative cell and tube cell. Thus, the pollen grain of Pinus is sheded at four-celled stage when it consists of two vegetative prothallial cells, a generative cell and a tube cell.
Q4.   ‘Chilgoza’ a gymnospermic seed that is eaten as dry fruit is produced by
  •  Pinus roxburghii
  •  Pinus geradiana
  •  Ginkgo biloba
  •  Cedrus deodara
(b) Chilgoza a gymnospermic seed that is eaten as dry fruit is produced by Pinus gerardiana

Q5.   Which of the following statement is correct about the gametophytic stage in the alteration of generation with in the life cycle?
  •  Generation that produces the gametes
  •  Generation that produces the spores
  •  Generation that produces vascular tissue
  •  The diploid generation
  (a) Gametophyte is gamete bearing, haploid multicelled stage of many plants, beginning with haploid spores and ending at fertilisation

Q6.   Choose the incorrect statement
  •  Double fertilisation is unique to gymnosperms and monocotyledons
  •  Sequoia, a gymnosperm, is one of the tallest trees
  •  Phaeophyceae members possess chlorophyll-a, c, carotenoids and xanthophylls
  •  Moss is a gametophyte, which consists of two stages namely, protonema stage and leafy stage
(a) True fertilisation together with triple fusion is known as double fertilisation, a unique phenomenon only occurs in angiosperms (absent in gymnosperms with few exception) and first time demonstrated by Nawaschin in Fritillaria and Lilium

Q7.   The gametophyte of moss is
  •  Seta
  •  Capsule
  •  Zygote
  •  Protonema
(d) Protonema is the juvenile stage of moss. It results from the germinating meiospore. When fully grown, it consists of a slender green, branching system of filaments called the protonema

Q8.   Calyptra develops from
  •  Venter wall of archegonium
  •  Outgrowth of gametophyte
  •  Neck wall of archegonium
  •  Paraphysis of the archegonial branch
(a) Calyptra is a covering developed from the ventre of archegonium in bryophytes and pteridophytes. It acts as a transpiration shield around the immature capsule and provides protection to the young capsule.

Q9.   A fern differs from a moss in having
  •  Swimming archegonia
  •  Swimming antherozoids
  •  Independent gametophytes
  •  Independent sporophytes
(d) A fern (pteridophyte) differs from a moss (bryophyte) in the presence of independent sporophyte, while in moss the sporophyte is simpler than the gametophyte and remains attached to the parent gametophyte throughout its life. This sporophyte is dependent upon gametophyte partially or wholly for its nutrition.

Q10.   The correct names of gymnospermic plant A,B and C shown in figure below are

  •  A-Cycas, B-Ginkgo, C-Pinus
  •  A-Cycas, B-Pinus, C-Ginkgo
  •  A-Ginkgo, B-Cycas, C-Pinus
  •  A-Pinus, B-Cycas, C-Ginkgo
(b) A- Cycas, B-Pinus, C-Ginkgo
