Subject- Science

2. INTRODUCTION:
We all know how plants and trees are so
important to us. We all need oxygen and these
plants gives us oxygen and absorbs carbon
dioxide. In this chapter we will learn about how
plants prepare their food. About the seed and
its structure. How plants germinate and grow.
We will also learn how plants reproduce. How
seeds dispersed.
I have discussed these in a very simple way
using activities which will help to learn the
concept easily.

3. Learning Objectives:
Student will learn how plants prepare their
food.
To know about Reproduction in plants
-By seed
-By different parts of plants.
Students will learn about the Structure of
seed and seed germination.
To know various ways of seed Dispersal.

4. Teaching Methodology:
•Explanatory method
•Discussion cum lecture method.
•Questionnaire method
Teaching Aids:
•Science Text book “My Living World” Class- V
•Audio- Visual Aid, Diagrams and charts
•White Board, White Board Marker

5. Stomata- Stomata are the tiny pores present on
the leaf surface.
It helps in exchange of Carbon dioxide and oxygen
in leaf.
Chlorophyll- Green pigments in leaves of plants. It
is essential for the process
of photosynthesis.
Some plants are insectivorous.
Eg. Pitcher plant, venus flytrap, butterworts etc
HOW PLANTS PREPARE THEIR
FOOD
Photosynthesis is a process where
plants use _________ from the sun
and takes ___________ from the air
and ________from the soil. It
converts into ___________to feed
the plant and _____________is
given out in the air.
water, light, oxygen, sugar, carbon dioxide

6. REPRODUCTION IN PLANTS:
Reproduction through seeds.
The baby plant starts growing
from the seed when it gets
appropriate amount of
Air, Water, Soil, Temperature.
Lets discuss structure of seed:
Reproduction: The process by which living things produce more of its own kind.
• Hole that allows water to enter the seed: Microphyle

7. Seed Germination

8. ACTIVITY
Take some seeds of gram or beans. Put them separately in 4 jars.
Label jars as A,B,C & D.
Keep them for 4-5 days under the conditions given below.
JAR- A: Put seed on moist cotton at room temperature.
JAR- B: Keep seed without water at room temperature.
JAR-C: Put seed in that jar filled with water at room temperature.
JAR-D: Put the seed in moist cotton in an ice box or freeze.
After 4-5 days observe the seeds kept in jars.
What do you observe?
Which jar seed been germinated and why?

9. Reproduction through different parts of plant:
Leaves, Roots, Underground stem, Stem cutting.

10. SEED DISPERSAL
By Bursting/ Cracking
By Wind
By Birds & Animals
By Water
The process of transfer of seeds to different places is called Seed Dispersal

11. ACTIVITY on Seed Dispersal
Write seed dispersal ways or agents for above
WIND WATER ANIMALS/HUMAN CRACKING/ BURSTING
Lotus
Water Lily
Lady finger

12. Learning Outcomes:
Students will understand how plants prepare their
food by photosynthesis process.
Students will able to know the structure of seed and
conditions required for seed germination.
Students will able to understand how plants
reproduce their own kind.
Students will able to know seed dispersal, dispersal
through different ways.

13. Assignments:
Draw labelled diagram of the following:
Photosynthesis, Structure of Seed, Stages of Seed
Germination
Write all the methods of seed dispersal.

Have you ever thought of panting a sapling on your birthday or gifting sapling as
return gift to your friend? Do such activity help to save environment?
