This document outlines an innovative lesson plan about plant hormones taught by teacher Kavitha S Mohan. The lesson introduces students to key plant hormones like auxins, cytokinins, gibberellins, ethylene, and abscisic acid through group activities and discussions. Students are divided into groups, each assigned a hormone to research its sources and functions. Concepts taught include how different hormones promote growth or act as inhibitors. The lesson aims to develop students' factual, conceptual, procedural and metacognitive knowledge of plant hormones.

3. CLASS ROOM INTERACTION PROCEDURE PUPIL RESPONSES
Introduction
Teachermakesa rapport withstudentsbyaskingquestionsrelatedtocontextual
Situation.
Teacherstarts a discussiononthe obvious effectsof humanhormones and
ask questions
1)whatdo you knowaboutdifferenthumanhormones ? pupil says,plant also
Teacher asks studentstothinkaboutdifferencesbetweenlittle boys contains hormones
and men and between littlegirlsand women. Reinforce the conceptsthat
humanhormonesare verypotent,have alotof individualjobs,andare found
inextremelysmallamounts.Teacherasksquestions
1)How a saplingbecome agianttree ?
Teacher Says,Today we are going to learn in a different approach about plant pupil says yes
Hormones.
Presentation
ACTIVITY-I
Teacher explains that there are two types of hormones in plants pupil listens carefully
They are
Growth promoters Growth inhibitors
Teacher divides the students into groups based on the hormone(card)
obtained and ask them to disscuss about it .

4. Group auxins
Group auxin lists out the sources and functions of hormone Group auxins list out
Sources –germinating seeds ,stem tips ,root tips ,leaves , the sources and
leaf buds functions
Functions –role in the dominance of terminal bud
Elongation of stem cells ,growth of lateral roots
Role in phototropism
Eg;
Group cytokinins
Sources –produced at the tip of roots and transport Group cytokinins
through xylem list out the
Functions-accelerating cell growth and cell division sources and functions
Germination of seeds,prevents fruit dropping
Eg :
Elongation of stem cells
prevents fruit dropping

5. Group gibberellins
Sources –germinating seeds
Embryo,stem and root tips Group gibberellins
Functions-germination of seeds,elongation of stem , list out the
Breaking down of stored food sources and
Sprouting of leaves functions
Group ethylene
Sources-produced in roots and diffuse to other parts
Functions –prevents cell division Group ethylene lists
Causes ripening of leaves and fruits out about it features
Group abscisic acid
Sources-produced in mature leaves and diffuse to other Parts
Functions-Prevents cell division and growth Abscisic acid lists
Causes dropping of mature leaves and fruits out their roles
Helps in leaf formation
ripening of fruits

6. After that the teacher explains about each hormone .Then she gives the
activity sheets and asks them to fill it .
QUESTIONS
1) seed germination
(a) students do the
Leaves sprout
(b) activity.Then teacher
discuss the answers
Stem grows Gibberellins/ cyokinins,
gibberellins,
(c) auxins/ gibberellins,
ethylene, abscisic acid
Mature leaves
(d)
Falling of leaves
Causes dropping of mature fruits

7. Consolidation
Plant hormones are essential for the growth and development of plants.
ACTIVITY -II
Teacher gives the activity card and explains about it suppose
five planthormonesare placedona roundcirculartable
ina clockwise direction.The hormonewhichplaysanimportantrole
in phototropismis placedinbetweenthe cytokininsand
the hormone involvedinfruitripening.The hormonewhich
is a plantgrowth inhibitorisplaced tothe leftof Ethylene.
The hormone whichproducedinthe germinatingseedsisplaced
to the rightof cytokinins.
Identifythe orderof placementandmarkedinthe circle givenbelow
Then the teacher explains the answers and asks review questions:
Pupil listens to the
answers and the
Explanations.
The answers are :
Gibberellins,cytokinins,
auxins , ethylene,
abscisic acid

8. Review questions
1)Listout the major planthormonesandtheirfunctions?
Follow up activity
1) Prepare a flowchartof planthormonesandtheirfunctions?
2) prepare a crosswordpuzzle forplanthormones .
