-it has scattered vascular bundle of stem
-they have fibrous root system
-they posses parallel venation
(1b)
-B-it is reproductive part of A
-C-it is female part of A
-D-it is fruit of A
(1d) D is seed.
it is a monocotyledonous plant seed it originate from
from the ovule of the female flower/ovary.
The seed is made up of an outer testa and a inner
tegmen, the seed has only one cotyledon and the embryo consist of a plumule and the radicle.
