The document describes an innovative lesson plan about plant hormones taught by teacher Nandini. Students were divided into groups based on cards describing different plant hormones and their functions. The groups then discussed and presented on auxins, cytokinins, gibberellins, ethylene, and abscisic acid. Students completed an activity sheet matching hormones to their roles in seed germination, stem and leaf growth, fruit ripening, and leaf falling. The teacher reviewed the answers and assigned a follow up activity to create a hormone flow chart or crossword puzzle.

1. INNOVATIVE LESSON PLAN-A card play on plant hormones
Name of the teacher : Nandini.s Standard : x
Name of the school : St Thomas school Strength :
Subject : Biology Date :
Unit : The chemistry behind responses Period :
Topic : Plant Hormones Time : 40 minutes
Curricular statements 1) The learner acquires knowledge about plant hormones(phytohormones)
2) To understand the different types of plant hormones and their function
In the plant body
3) To attain conceptual ideas regarding the influence of hormone on plant
growth
4) To develop positive attitude towards maintaining a healthy cultivation
Practices
Learning outcomes
Factual knowledge 1) The learner recalling the term "plant hormones"
Conceptual knowledge 2) The learner understanding about the source of production of plant
Hormones
Procedural knowledge 3) The learner gives reason why plant bend towards the sunlight
4) The learner communicating with others about the role of Plant
hormones in the growth and development
Metacognition level 5) The learner comparing the action of growth promoters and inhibitiors
6) The learner evaluating the features of plant chemical messengers
Attitude 7) The learner develops positive attitude towards the growth of plant
In response to different plant hormones

2. Content analysis Plant Hormones .Auxin,Cytokinins,Gibberllins ,Ethylene,Abscisic
Terms acid,artificial plant hormones
Facts 1) The hormones produced by the plants are called phytohormones
2) The plant hormones produced by meristematic cells located at different
plant parts
3) Auxins play a major role in the dominanace of terminal buds
4) Auxin helps in the production of female flowers
5) Auxin helps in the elongation of stem cells
6) cytokinins helps in accelerating cellgrowth and cell division
7) Cytokinin prevents the droppings of flowers and leaves.
8) Gibberellin helps in the germination of seeds
9) Ethylene produced in the roots and diffuse to other parts
10) Ethylene prevents cell division
11) Ethylene causes maturation and ripening of leaves and fruit
12) Abscisic acid produced in mature leaves
13) It helps in the dormancy of seeds and buds.
Concept
Major 1) Messengers in plants
Minor 2) Growth promoters
Pre-requisites 1) The learner already knows that hormone plays a key role in controlling the
Growth and development

3. Teaching –learning 1) cards showing the sources and functions of different phytohormones
Resources 2) Activity sheets
3) Follow up activities

4. TEACHING AND LEARNING INTERACTION PUPIL RESPONSE
Introduction
Teacher starts a discussion on the obvious effects of human hormones.
and ask what the students know about different human hormones etc. pupil says , plant also
Teacher asks students to think about differences between little boys contains hormones
and men and between little girls and women.Reinforce the concepts that
human hormones are very potent, have alot of individual jobs, and are found
in extremely small amounts. Now ask about plant hormones. How a sapling
become a giant tree ?
Today we are going to learn in a different approach about plant pupil says yes
Hormones.
Presentation
Teacher explains that there are two types of hormones in plants pupil listens
They are carefully
Growth promoters Growth inhibitors
I am going to give you some colour cards to each student which conatins
the functions of each plant hormones. students form different
you should form groups based on the hormone(card) you obtained groups based on the
and disscuss about it .After that each group should share hormone they

5. the information they obtained obtained
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

6. 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
Helps in leaf formation
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
ripening of fruits

7. 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
Causes dropping of mature fruits
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
Stem grows

8. (c)
Mature leaves
(d)
Falling of leaves
Fill the flow chart with correct hormones
2) suppose five plant hormones are placed on a round circular table
in a clockwise direction .The hormone which plays an important role
in phototropism is placed in between the cytokinins and
the hormone involved in fruit ripening.The hormone which
is a plant growth inhibitor is placed to the left of Ethylene.
The hormone which produced in the germinating seeds is placed
to the right of cytokinins .
Identify the order of placement and marked in the circle given below

9. Anwers 1)
Gibberellins/ cyokinins , gibberellins, auxins/ gibberellins,
ethylene, abscisic acid
2)
Gibberellins,cytokinins ,auxins , ethylene, abscisic acid
Pupil listens to the
Then the teacher explains the answers and ask review questions : answers and her
explanations
