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?

Presentation


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?

  2. Task 1:
    a) The 5 Kingdoms

    b) They are classified by their Structural Differences.

    c) It was started 2,300 years ago where Aristotle grouped life forms into animals and plants. Carl Woese proposed the most recent changes of the classification System in 1990 introducing- archaea, bacteria and eucarya by the type of RNA in their cells.. Charles Linneaus created the actual groups of the basis of the modern classification system

    d) Cells, Organization, Energy Use, Homeostasis, Growth, Reproduction

  3. a) What is the modern classification system used by biologists?

    The modern classification system used by the biologists is 5 kingdoms.The five-kingdom system of classification for living organisms includes the prokaryotic Monera and the eukaryotic Protista, Fungi, Plantae and Animalia.

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

    They are classified according to their type of outer covering, habits, type of reproduction, ability, extra organs. The basis of classification is the classification system made by Carolous Linneas which classifies the organisms into the various classes such as the following, kingdom, phylum, class, order , family, genus, species.

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

    Robert Whittaker

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

    The different other characteristics are by Phylum, Class, Order, Family, Genus and Species.

  4. a) What is the modern classification system used by biologists?

    Ans: The 5 kingdoms in biology, namely Animalia, Plantae, Fungi, Protista and Monera.

    b) How are organisms classified? What is the basis of classification? (refer to the examples of platypus and legless lizard)

    Ans: Physical and Structural similarities or differences.

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

    Ans: Carolus Linnaeus (1707–1778)
    Ernst Haeckel 1674
    Herbert F. Copeland 1938
    Édouard Chatton 1960
    Robert Whittaker 1969
    Carl Woese 1977 & 1990
    Thomas Cavalier-Smith 2004

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

    Taxonomic rank. From the top is life, domain, kingdom, phylum, class, order, family, genus, and followed by species.

  5. a) What is the modern classification system used by biologists?

    The 5 kingdoms of Animalia, Plantae, Monera, Protista and Fungi.

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

    They are grouped according to their structural differences.

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

    Carolus Linnaeus, then Ernst Haeckel, then Édouard Chatton, then Herbert Copeland, then Robert Whittaker, then Carl Woese, who then created the next system and lastly Thomas Cavalier-Smith.

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

    The are also the taxonomy rank, where there are domain, kingdom, class, phylum, order, family, genus and species.

  6. I remembered why I knew it was a legless lizard. but not a snake, the head is more streamlined than a snake's
