Topic: Classification and Biodiversity
Year Level: 2nd year High School
At the end of 60 minute lesson 75% of the II- St. Agnes students will be able to: 1.
name the 5 kingdoms and classification in biodiversity;
identify the difference between each kingdom;
write down neatly different kinds of organisms according to what kingdom they belong.

Let us all stand and pray.
In the name of the Father and of the Son
and of the Holy Spirit…

I will check your attendance today.
Who is absent?
Let us have now our review first. What
was topic yesterday?
Raising their hands.
The teacher calls one student.
Yesterday Miss, we tackled about
the characteristics of living things. Very good! Yes, it was all about the
Characteristics of living things and these are?
Give two characteristics.
Raising their hands.
The teacher calls another student.
1. Living things usually, they have definite form and characteristics size within certain limits.
2. Capable of metabolic activity.
Yes, that’s right! There is difference in size
3. Capable of responding to and metabolism.
Another two characteristics?
4. Capable of reproduction.
Very good! And the last one?
5. It has a definite life cycle.
Okay! Very good! You really remembered
well our discussion yesterday.
We are done for the characteristics and
so now, let’s proceed.
Class what do you notice about the grocery lanes?
There is arrangement and In the department stores? In library?
Can you imagine, what will happen if grocery,
It’s hard to find things and department stores and library if they don’t use
how to identify them. a classification system? What do you think will
So, class, for today’s topic, it has something to do
with classification. It is the classification of organisms
and the 5 kingdoms in which they belong.
Do you want to know what are these classification
Class, there are about 1.8 million species who have given
scientific names and nearly 2/3 of these are insects. The
total number of living species is estimated to be between
12 and 14 million. However, there are still organisms that
are not yet discovered and today it is still counting.
We know now that we need to classify organisms but then, why classify organisms? •
To represent relationships among organisms.
To make things easier to find, identify and study.
To understand our own evolution.
Present by powerpoint presentation the biological classification of organisms.
Five kingdom classification
Criteria of classification –
Cell structure, thallus organisation, mode of nutrition, reproduction, phylogenetic relationship. R.H. Whittaker (1969) – divided organisms into five kingdoms
Plants are immobile, multicellular eukaryotes that produce their food by photosynthesis and have cells encased in cellulose cell walls.
Examples: Ferns, pine trees, roses
Animals are multicellular, heterotrophic eukaryotes that are capable of...
