4. Flowers are beautiful and sweet smelling.
we use certain fragrant and colourful
flowers for adorning hair and for other
decorations.
many flowers have in them nectar too.
Flowers are the reproductive structure of
a flowering plant.
Flower is a modified shoot.
Specialized for sexual reproduction.

5. A flower consist of a very shot axis, called
thalamus.
Arranged on the thalamus, one above the other,
are the floral whorls.
Typically, flower has four floral whorls.
Namely from base to
top,calyx,corolla,androecium,gynoecium or pistil.
Base of the flower called receptacle.

6. Stalk of an individual flower in an
inflorescence is called pedicel.
The outermost whorl of floral organs are
called calyx.
The second set of floral organs are called
corolla.
The male reproductive organ of flower is
called Androecium.
The female reproductive part of the
flower is called gynoecium.

8. Calyx constitutes the outermost
whorl of floral organs.
Its component parts are the
sepals.
Sepals are usually green in colour.
Enclose the rest of the flower in
the bad stage, however they can be
absent or prominent and petal like
in some species.

9. Corolla constitutes the second
set of floral organs.
It is situated in between the
calyx and is usually composed
of single whorl of petals.
Petals are generally thin,
brightly coloured and some
times sweet smelling to attract
insects that help the process
pollination.

11. Androecium is the male sex organ in flower.
It is made up of a number of sramens.
The slender stem like part of the stamen is
called filament and the bulged tip is anther.
The anthers are seen in the centre of the
flower.
The pollen from the anthers of one flower is
transferred to the stigma of another flower
through wind or by animal, especially insects.

13. Gynoecium is the female sex organ in flower.
Each gynoecium is formed of one or more
carpels.
Gynoecium consist of stigma, style and
ovary.
The carpel or multiple fused carpels forms a
hollow structure called an ovary.
Ovary produces ovules.
Ovules are found inside the ovary.
