(b) It is resistant to wall attacking antibiotics
such as penicillin.
(c) It is pleomorphic and varies in shape
from spherical to branched filamentous
structure and is called ‘joker of the plant
kingdom.’
(d) It is unicellular, non-motile gram +ve
prokaryote which lacks a distinct cell
wall.

Plant Kingdom



  1. (b) Coralloid roots of Cycas. It contains
    symbiotic cyanobacteria, which fix nitrogen

    and in association with root tissues produce


beneficial  aminoacids  Asparagine  and     
Citrulline.


  1. (b) It is Marchantia, a bryophyte. A, B, C are
    identified as Archegoniophore, gemma cup
    and Rhizoids.

  2. (b) A-Circinate vernation in the compound
    leaves of cycads, B-Circinate vernation is the
    manner in which fern frond emerges, it is
    tightly curled so that tender growing tip of
    the frond is protected within a coil.

  3. (c) The following diagram represents
    Haplontic, Diplontic, Haplo-diplontic life
    cycles in plant kingdom.

  6. (a) A- Strobilus, B- Node and Internode,
    C- Branch, D- Rhizome

  7. (d) A- Laminaria, B- Fucus, C- Dictyota,
    D- Porphyra

  8. (c) A- Equisetum, B- Dictyota,
    C- Polysiphonia, D- Porphyra

  9. (c)A- Selaginella, B- Equisetum,
    C- Salvinia, D- Funaria

  10. (b) The diagram is related to Sphagnum which
    is monoecious and belongs to mosses and
    used as packing material for transshipment
    of live specimens
