Q1.  Consider the following statements I. The liverworts grow usually in moist, shady habitats such as banks of streams, marshy ground, damp soil, bark of trees and deep in the woods II. The leafy members of liverwort have tiny leaf-like appendages in two rows on the stem-like structures Choose the correct option
  •   I is true, II is false
  •   I is false, II is true
  •   I and II are true
  •   I and II are false
(c) Both statements are true

Q2. The cones bearing megasporophyll with ovules are called
  •   Male strobili
  •   Female strobili
  •   Megasporangia
(b) The cones bearing megasporophyll with ovules are called female strobili or megasporangia or macrosporangiate. Both megasporophyll and microsporophyll may be present on same plant (., Pinus) or may be present separately

Q3.   Protonema is the stage in the life cycle of
  •   cycas
  •   funaria
  •   selaginella
  •   mucor
Protonema is the juvenile stage of moss resulting from the germinating meiospore and consists of a slender, green, branching system of filaments. In the protonema stage is only vegetative and transitory, which precedes the upright, leafy gametophyte.

Q4.  Study the following and identify two characters found in both I. Formation of motile male gametes. II. Formation of haploid endosperm. III. Formation of sporophyte directly from gametophyte without gametic union. IV. Formation of archegonia in female gametophyte. The correct match is
  •   a) I and IV
  •   I and III
  •   II and IV
  •   III and IV
Haploid endosperm is formed only in while apogamy is found only in

Q5.This place in India is called ‘The Golden Mine of Liverworts’.
  •   Eastern Himalayas
  •   Western Himalayas
  •   Western Ghats
  •   Eastern Ghats
  (b) The liverworts are widely distributed over the earth’s surface but are far more numerous I the tropics than in other parts of the world. In India, they are abundant in the Western Himalayas, where rainfall is the heaviest.

Q6.  Embryo sac consists of
  •   One egg cell
  •   Two synergids
  • Three antipodal and two polar nuclei
  •   All of the above
(d) An ideal embryo sac contains 7-cells and 8-nuclei. 3 cells are present at the micropylar end and form egg apparatus, mid of which forms egg cell and rest two lateral form synergids. One cell present in the centre of embryo sac, known as central cell and contains two nuclei and rest three cells are present at chalazal end for antipodal cells

Q7. Pteridophytes are also known as
  •   Cryptogams
  •   Vascular crytogams
  •   Amphibious plants
  •   Phanerogams
(b) Pteridophytes are called vascular cryptogams because among cryptogams the vascular strands are present only in pteridophyte. All the vegetative parts possess vascular tissues (i.e., xylem and phloem)

Q8. The endosperm in angiosperms develops from
  •   Zygote
  •   Secondary nucleus
  •   Chalazal polar nucleus
  •   Micropylar polar nucleus
(b) Endosperm in angiosperms develops as a fusion product of secondary nucleus with male gamete. Secondary nucleus is diploid structure formed by fusion of haploid chalazal polar nucleus and haploid micropylar polar nucleus. Zygote is formed by the fusion of male gamete with egg

Q9. Archegoniophore is present in
  •   chara
  •   adiantum
  •   funaria
  •   marchantia
(d) IN a bryophyte, the archegonia (female sex organ) are borne on special branches called archegoniophore or female receptacles. Each archegoniophore has rows of archegonia protected by involucre or perichaetium.

Q10.  Which of the following plant cells is not surrounded by a cell wall?
  •   Root hair cell
  •   Stem hair cell
  •   Gamete cell
  • Bacterial cell
(c) Gamete is the haploid reproductive cell that fuses with another gamete to form a diploid zygote. These are not surrounded by the cell wall. On the other hand, root hair cell stem hair cell and bacterial cell, all possess a well defined cell wall.
