Biodiversity Lesson 1

Here are 2 unique Australian species. What are they?

Task 1 (30 minutes)

Work in groups to conduct online research to the following questions:
a) What is the modern classification system used by biologists?

b) How are organisms classified? What is the basis of classification? (refer to the 2 unique Australian species)

c) How did the modern classification system come about? Who were the biologists who contributed to this area of study?

d) What other key characteristics are there to describe the modern classification system?


Task 2 (25 minutes)

Review the key characteristics of the organisms in the 5 kingdoms.

Group 1 – Monera, Protista, Fungi
Group 2 – Plantae
Group 3, 4 & 5 – Animalia (Invertebrates & Vertebrates)

Post your group research in the science blog.

Task 3 (Homework, Individual)
Read the post uploaded by the other groups.

Select 3 groups of organisms and provide 3 facts that were not mentioned in the group’s research. Post your findings in the comments section.

Task 4 (Homework, Reflection, Individual)

1.                  What is biodiversity?
2.                  In one or two sentences, explain why biodiversity is important to us.
3.                 What is the key understanding of this lesson?

    a) Biological Classification, or scientific classification in Biology is the method in which biologists categorize organisms by Biological type.

    b) They are classified according to shared physical characteristics. The groups are Monera, Protista, Fungi, Plantae and Animalia (Invertebrates & Vertebrates) The basis of classification is from the majority characteristics.

    c) The modern classification system was revised to improve consistency with the Darwinian principle of common descent by Carolus Linnaeus.

    d) The organisms are grouped according to shared physical characteristics.

  3. Group Amrit Vivek Kun Yao

    a) The Linnaeus' system.

    b) We can describe organisms by Species, Genus, Family, Order, Class, Phylum, Kingdom.

    c) It's based on relationships between one species to another to create a group, based upon morphology and other physical characteristics and to find out the relationships in genetic structures of living things. They are Carolus Linnaeus and Charles Darwin.

    d) Traits and common doings of the creatures.

    a) Taxonomy

    b) They are classified by ....


    c) Modern biological classification came from the work of Carolus
    Linnaeus, who grouped species according to shared physical

    These groupings have since been revised to improve consistency with
    the Darwinian principle of common descent.

    Biological classification belongs to the science of biological

    d)They are classified according their common physical characteristics
    and traits

  5. Task 1
    Zhi Xiang's group
    a)Biological classification is the method where scientists classify organisms by biological types.

    b)Animals are classified based on which of the 5 kingdoms of life they belong to,phylum,order,family,genus and species.

    c) Contributions to plants classification came from de Jussieu in 1789 and Candolle. A major influence on plant systematics was the theory of evolution resulting in the aim to group plants.

    d)Organisms are classified to similar physical characteristics.

  6. Task 1
    a)The 5 kingdom system.

    b) They are classified by breaking down the groups of animals down to smaller size by what characteristic they are alike like
    This can be varied into any order and also any new kinds of classification can be added.
    There can be many basis of classification for organisms like the ones shown above

    c) The modern classification came about by Carolus Linnaeus,who grouped species according to shared physical characteristics

    d)1.Body symmetry
    2.Type of body skeleton
    3.Segmentation; multiple body units
    4.Body covering
    5. Presence of body appendages

    1. Flatworms
    -They are unsegmented, soft-bodied invertebrate animals.
    -They have no body cavity, No specialized circulatory and Respiratory organs, which
    restricts them to flattened shapes that allow oxygen and nutrients to pass through
    their bodies by diffusion.

    2. Roundworms (Found out the characteristics of this)
    -Roundworms are smooth, cylindrical and a light iridescent color and body is not
    -Adult roundworms can grow up to 4 inches long
    -Roundworm can grow in an animal's digestive tract while feeding on nutrients

    3. Segmentek Worms (Also known as Annelids or latin word would be, anellus.)
    - These worms have segments in their body.
    - Each segments contain the same set of organs.
    - This means that sometimes, when a segmented worm is cut, it won't die and would
    're-grow' again.
    Examples of these worms are,
    -Earthworms (the popular one)

    -They are soft bodied animals and most have a hard shell to protect its internal
    -They are all made up of three regions : a head, a singular muscular ‘foot’ and mass
    of internal organs.
    Molluscs with shells
    -For example squid, sea slugs, octopus, etc.
    Bivalves is the only group under molluscs that does not have a form of a head and a
    radula (A special feeding organ)
