1. UNIT 9: THE
BIODIVERSITY OF THE
LIVING THINGS

2. BIODIVERSITY AND ADAPTION
 Biodiversity is the great variety of different forms of
life or species that form the biosphere.
 They transform or evolve into different organisms or
species over millions of years.
 Biological evolution is the slow and gradual changes
that living beings have undergone in the history of the
Earth.

3. THE HISTORY OF LIFE ON EARTH:
EVOLUTION
 Fossils are the remains of organisms or footprints of
past living things, which were buried under sediment
that formed sedimentary rocks.

4. ACTIVITIES
1. Explain what biodiversity is.
2. Some aquatic animals like dolphins are not fish. How
have they adapted to move in the water?
3.What is biological evolution?

5. ACTIVITIES
4.The following definitions refer to…
a) The variety of different forms of life in the
biosphere.
b)The process of slow changes that living beings have
undergone during the history.
c)The remains of organisms that lived in the past.

6. THE FIVE KINGDOMS
 Monera kingdom: Ex: Bacterias
 Protoctist kingdom: Protozoa and Algae.
 Fungi kingdom: Ex: Mould and Mushrooms.
 Plant kingdom: Ex: Oak tree
 Animal kingdom: Ex: Dog

7. THE MONERA KINGDOM
 The Monera kingdom contains unicellular
prokaryotic organisms. Ex: Bacteria
Vibrio
 Nutrition: autotrophic or heterotrophic.
 Saprophytes, parasites, symbionts.
 Reproduction: Asexual, cell division.
 Types of bacteria:
 Coccus: Spherical
 Bacillus: Elongated
 Vibrio: Curved
 Spirillum: Spiral

8. THE PROTOCTIST KINGDOM
 Prtoctists are unicellular and multicellular
organisms. They are eukaryotes and never
form tissues.
 Types:
 Protozoa: They are heterotrophs. Ex: Amoebae
 Algae: They are autotrophs and perform
photosynthesis.

9. ACTIVITIES
1.Draw the different types of bacteria.
2.The bacteria that live in our digestive system
help us digest food and produce vitamins. Are
they parasites, saprophytes or symbionts?
3. The bacteria that live inside the root of
leguminous plants are:
a)Parasites
b)Symbionts
c)Autotrophs

10. 4. Complete the following sentence:
Cells of Protoctist kingdom are_____________ and cells of
Monera kingdom are_____________ which means they
don’t have ______________.
5.Complete the following sentence:
Algae are____________ beacuse they make
photosynthesis. Their cells have_______________ like
the plants.

11. THE FUNGI KINGDOM
 Fungi are unicellular or multicellular organisms.
 They are eukaryotes and they have cellular wall.
 They dont’ form tissues.
 They are heterotrophs.
 Ex: Mould, yeast and mushroom.
 Nutrition: Saprophytes,Parasites, Symbionts.
 Reproduction: They produce cells called spores.
 Interaction: They live in the soil, in dark places.

12. PARTS OF A FUNGI
