LESSON PLAN…1….
CLASS:- 7 DATE:………………
SLO:-STUDENTS WILL BE ABLE TO DESCRIBE THE INTERNAL
STRUCTURE OF
LEAF
1.
Opening:
1.1.
Assessing Previous Knowledge
1.1.1.
What
are the different parts of a plant which we can see?
1.1.2.
Which
part of plant below air in different seasons?
1.1.3.
Draw
a shape of leaf with some wains and ask about the shape.
1.1.4.
Through
which part a plant prepares its food?
1.1.5.
Through
which plant food is transported to other parts?
2.
Introduction to new material:
2.1.
In
plants, leaves are the major site of photosynthesis.
2.2.
They
are often referred as food factories of nature.
2.3.
A
leaf is made up of many layers those are sandwiched between two layers i.e. the
upper epidermis and lower epidermis.
2.4.
The
upper epidermis is covered by waxy cuticle which reduce evaporation from the
upper surface and lower epidermis has stomata pores for exchange of gases.
2.5.
Palisade
mesophyll cells are tightly packed elongated cells where most food production
takes place
2.6.
Spongy
mesophyll cells are loosely packed with large intercellular spaces, where the
exchange of gases take place more efficiently. Conducting tissues consist of
xylem and phloem. Xylem transport water and minerals and phloem transport food
to other parts of plant
