- (a) Androecium of this flower possess five stamens,
polyandrous, alternipetalous and epipetalous. Anthers are
bithecous, basifixed and inferior. Gynoecium is bicarpellary,
syncarpous, ovary is superior, placed obliquely and bilocular.
Placentation is axile with many ovules in each loculus.
(b) The given floral diagram is of Solanum nigrum which
belongs to family Solanaceae.
(c) Plants of this family are used as
(i) Vegetables e.g., Potato, tomato, brinjal, etc.
(ii) Medicines e.g., Atropa belladona yields belladona
which is used as topical pain reliever for dilation
of pupil of the eye. Roots of Withania somnifera
(Ashwagandha) are used to cure rheumatism and
general weakness. Different parts of Solanum
surattense are useful in treating asthma, bronchitis,
leucoderma, etc. - (a) P is fused epicarp and thalamus, Q is mesocarp, R is
papery endocarp, S are seeds and T represents placenta in
fruit.
(b) The given figure is of pomegranate (Punica granatum) which
is a balausta berry. It is a pseudocarpic berry in which the
syncarpous pistil consists of two rows of fused carpels.
(c) The hard rind of pomegranate is made up of exocarp and
part of mesocarp while the white papery layer that covers
the individual groups of seeds is derived from endocarp.

(b) The given figure shows the conjoint, collateral and closed
type of vascular bundle. These are found in monocot stem
where a large number of vascular bundles are scattered in
ground tissue i.e., atactostele.
(c) Xylem is endarch and arranged in the form of letter
Y. Metaxylem generally consists of two large oval or
rounded vessels lying at the upper two angles of xylem.
The metaxylem vessels have pitted walls. Protoxylem has
a few (2-3) small oval vessels. They lie at lower angle of
xylem. The vessels of protoxylem show spiral and annular
thickenings. Xylem parenchyma and a few fibres are found
just outside them. Some of the protoxylem vessels and
xylem parenchyma cells dissolve or separate during the
