Calyx[B.B]
The individual
unit of a calyx is called sepals. A sepal is usually green and leaf like.
Calyx protects the floral parts of the bud stage, and is the first whorl of
the flower. Sometimes it may be modified to do other functions. In mussaenda
one of the sepals grows out as a large petal like structure. Calyx is said to
be polysepalous and when they are united it is called as gamosepalous.
Teacher makes the
pupils to observe the chart and specimen.
1. What is the first whorl of the flower?
calyx
2. What is the name of calyx, if the sepals are free?
Polysepalous
Corolla
Teacher explains the corolla by using the real specimen.
Corolla is the
second whorl of a flower. It is composed of petals. They are brightly
coloured and it attracts the insects for cross pollination. If all the petals
are similar in size and shape, it said to be regular. If they are vary in
size and shape they are called as irregular. When the petals are free, they
are called polypetalous and when they are united they are called as gamopetalous.
1. Name the second whorl of the flower?
Corolla
2. What is called polypetalous?
If the petals are free, they are called
polypetalous.

are present in the lateral side?

Pupil identifies polypetalous irregular corolla.
Pupils recognizes about androecium

3. What is called gamopetalous?
If the petals
are united they are called as gamopetalous.
Papilionaceous corolla is an example for polypetalous.
There are five petals resembling a butterfly. The posterior petal is large
and outermost one is called the standard petal. There are two lateral tiny
petals and two anterior united keel petals eg crotalarious.
Teacher displays a chart with the picture of petals.
Teacher asks the students to point out the corolla by using the chart and
specimens.
Androecium[B.B]
Androecium or
the male part is the third whorl of the flower and it consists of stamens or
microsporophylls. Each stamen has a basal stalk, the filament and anther
lobes at its top. It is connected by means of a special tissue called
connective
Teacher explains Androecium by using chart and specimen.
1. What is the third whorl of the flower?
Androecium
2. What is the name of special tissue present in the top
of the Androecium?
Connective tissue

Gynoecium[B.B]
Gynoecium or
pistil forms the fourth what of the flower and it is female part of the
flower. It has a swollen base called ovary and a slender style that ends in
stigma.

specimens.
