  • Hi Jeff - you’re right and it is present in the cell walls of vascular plants. Lignin is present in wood, though non-woody is not the same as non-lignified. I’ve updated it now.

    Thanks for the heads-up - and for the article link!

  • I'm no botanist, but several sources I've seen say that ferns DO have lignin. Was this a typo or do you disagree? Also, I thought this was an interesting article about the evolution of lignin. Thanks for all your great resources...I use them in my IB classes regularly.

  • 2. Assessment Statements from the IB Biology Subject Guide. Extension: • How does taxonomy connect to the big ideas of: • Evolution? • Structure & Function? • TOK: What are the benefits of a single global naming system for species based on latin?

  • 6. Image from: http://en.wikipedia.org/wiki/Biological_classification Six Kingdoms from: http://en.wikipedia.org/wiki/Kingdom_(biology) Some examples of Phyla we need to know Kingdom Animalia • Porifera • Cnidaria • Platyhelminthes • Annelida • Mollusca • Arthropoda Kingdom Plantae (Plant phyla are better known as divisions) • Bryophyta • Filicinophyta • Coniferophyta • Angiospermophyta
  • 7. Image from: http://en.wikipedia.org/wiki/Biological_classification Tree of life, from: http://en.wikipedia.org/wiki/Phylogenetic_tree Click here for full size. As we move down the taxonomic levels, groups become smaller and more closely related. For example, the Phylum Chordata includes the Classes: Amphibia, Reptilia, Aves, Mammalia.
  • 8. Photo © Stephen Taylor What’s the common name for this species in your mother tongues? manusia
  • 9. Binomial Nomenclature “Two-name naming system” Homo sapiens Homo sapiensGenus name is capitalized species name is NEVER capitalized If it has been used in your piece of work already, the name can be abbreviated to: H. sapiens (or H. sapiens) typed binomial names MUST be italicized handwritten binomial names MUST be underlined Photo © Stephen Taylorhttp://en.wikipedia.org/wiki/Binomial_nomenclature
  • 10. Binomial Nomenclature From: http://en.wikipedia.org/wiki/Binomial_nomenclature Carolus Linneus (Carl von Linné) 1707-1778 http://en.wikipedia.org/wiki/Carolus_Linnaeus

  • 41. Dominoes: print 2-3 sets per group.
  • 42. Classification Dominoes spares • Groups of 2-4. • Each player needs a set of dominoes. • Put all the dominoes together & mix them up. • Deal out 6 dominoes per player. • The leftovers go in the ‘spare’ pile, face-down. Playing The Game: 1. Take one ‘spare’ and place it face-up on the desk. 2. The first player to spot that they can connect one of their dominoes goes first. 3. Play continues clock-wise until all players have correctly used all their dominoes. 4. If you cannot place a domino correctly on your turn, take one of the spares. Play passes you.
