(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.’

- (b) Coralloid roots of Cycas. It contains
symbiotic cyanobacteria, which fix nitrogen
and in association with root tissues produce
beneficial aminoacids Asparagine and
Citrulline.
- (b) It is Marchantia, a bryophyte. A, B, C are
identified as Archegoniophore, gemma cup
and Rhizoids. - (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. - (c) The following diagram represents
Haplontic, Diplontic, Haplo-diplontic life
cycles in plant kingdom. - (c)
