Teacher states that
Flower is a specialized

are modified into floral
parts.
Structure
-stalk (pedicel) supports
the flower
- the tip of the stalk may
be expanded to form cup
shaped receptacle called
thalamus.
-there are four whorls (
floral parts are borne on
the thalamus in four
whorls)
1st
whorl-green sepal,
collectively called as
calyx.
2nd
whorl- large brightly
colored petals,
collectively called as
corolla.
3rd
whorl- (male parts)
stamens, collectively
called androecium.
4th
whorl- (female parts)
pistil, collectively called
gynoecium.

all the four
whorls of

any one of
the whorl is
missing.

Understanding
Identify the
difference
between
essential and
non-essential
parts of the
flower
A complete flower is the
one in which all the four
whorls are present.
Incomplete flower is the
one, if any of the four
whorls are missing.
Essential parts of flower
are those that are
directly concerned with
reproduction. It consists
of stamens and carpels.
Non-essential parts are
simply helping parts
which either protect the
reproductive parts of the
flower or make the
flower attractive for
pollination.
It includes sepals and
petals
Sepal and petal together
is called perianth. When
the perianth is un-green
in color it is called
petaloid.
When the perianth is
green in color like the
sepal it is called
sepaloid. It includes
bract and necturus.

Question:
What is
difference
between
complete and
incomplete
flower.
Answer:
complete
flower- Flower
in which all the
four whorls of
the flower are
present.
Incomplete
flower- in
which, if one or
more parts or
whorls are
missing.
What is the
difference
between
essential and
non-essential
parts of the
flower?
Essential parts
are those that
are directly
concerned with
reproduction.
Non-essential
pats are those
that simply
help in
protecting the
reproductive
parts or make
the flower
attractive for
pollination.

SEXUALITY

FLOWERS
Bisexual
flower

Male flower
Female

Knowledge:
Recognize the

female flower,
bisexual and
unisexual
flower.
understand
Differentiate
between the
bisexual,
unisexual,
male and
female flower.
The anther on the stamen
produces pollen which
forms the male cells. The
ovary of the carpel bares
ovule which encloses the
egg cells.
The stamen and the carpel
are the male and female
reproductive parts of the
flower respectively.
Bisexual flower: which
consist of both stamen and
carpels?
Egg: rose, sunflower,
hibiscus, etc.
Unisexual flower: which
consist of either only
stamens or only carpels?
Eg: watermelon,
cucumber, etc.
Male flower: which
consist of only stamens.
Female flower: which
consist of only carpel?
Students listen and

the bisexual and
unisexual flower.

Question:
What is the

between
bisexual and

flower?
Answer:
Bisexual flower
which consist
of both stamen
and carpel.
Unisexual
flower: which
consist of only
stamens or only
carpel.
CONCLUDING STATEMENT: in today’s class we had learnt the structure of bisexual flower, the
difference complete and incomplete flower-essential and non-essential parts of the flower and the
sexuality in flower
5. RECAPITULATION BLACK BOARD WORK
1)Define flower
2) Which are the four whorl of the flower?
3)What is bisexual flower?
Flower is a specialized shoot in which the leaves
are modified into floral parts
The first whorl of the flower is sepal which is green
in color. The second whorl is the petal which is
brightly colored structure. The third whorl is the
stamen which is male reproductive parts
(collectively called androecium). The fourth whorl
is the pistil which is the female parts (collectively
called gynoecium.
The bisexual flower is the one which consist of
both stamens and carpels.
HOME WORK:
1) Draw a neat labeled diagram of flower.
