Origin of life

According to the Primordial Soup theory, life began in a pool of water, called ‘soup’ because it contained the kinds of chemicals needed to create life. Suddenly something happened – perhaps a bolt of a lightning hit one of the pools – and the chemicals reacted forming more complex molecules.

PART 1: Origin of life theories

  1. Open a Google Docs with the name: Report_ Origin_Life_G(N)(C).
  2. Watch the video beside and make the first part of your document, explaining the different theories about the origin of life a mode of introduction.



PART 2: The first cells

Life began at about 3900 Ma ago. The first cell was a prokaryotic cell. It is the simplest organization of living beings and from the Monera Kingdom.

  1. Now open your Science Bits. Look for the Unit: Formed by cells. Go to Explain part (pages 6 and 7) and extract the information to show the general information about the Monera Kingdom.
  • Kingdom:
  • Year of origin:
  • Characteristics of the prokaryotic cell:
  • Parts of the cell:

Include this information in your report.





PART 3: The origin of oxygen in Earth's atmosphere

What do you think about the origin of oxygen in Earth's atmosphere?

A mutation leads bacteria to perform photosynthesis. These tiny organisms are known as cyanobacteria. These microbes conduct photosynthesis: using sunshine, water and carbon dioxide to produce carbohydrates and oxygen...

  1. Watch this video (it has subtitles, so you can turn them on to understand it better).
  2. Continue your report explaining:
  • The characteristics of cyanobacteria.
  • Year of origin.
  • Effects of oxygen production.

PART 4: "The first eucaryotic cells and the Kingdom Protista

  1. Watch this video (it has subtitles, so you can turn them on to understand it better).
  2. Now open your Science Bits.
    • Look for the Unit: Formed by cells. Go to Explain part (page 9) and read it.
    • Look for the Unit: The Five-Kingdom System. Go to Explain part (page 5) and read it.

3. Then, finish your report including the information below:

    • Characteristics of eucaryotic cells (parts, organelles...).
    • Type of eucaryotic cells and differences.
    • Characteristics of Kingdom Protista.
    • Classification of Protists.
    • Add photos (touch them up and apply some effects with Gimp)
    • Use Inkscape to create some funny titles.

Conclusion:

Think about the the importance of cells evolution and how it affected to the evolution of the Earth and its layers.
