Interesting Facts- An Introduction into Taxonomy.

I hope you all can see that. Anyways, here's a really bad drawing I did just now on Paint for you. Below is what the numbered parts of a leaf/branch/whatever it's called.

  1. Stem
  2. Gland
  3. Bud
  4. Petiole
  5. Compound Leaf
  6. Leaflets
  7. Veins
  8. Leaflet Margin
  9. Apex
Terms You should know because my school forced me to learn them. 
  • Taxonomy- The Study of living things. 
  • Taxonomist- Someone who studies living things.
  • Linnaeus- Credited for starting taxonomy, the "Father of Taxonomy".
  • Binomial Nomenclature- Two names, genus species 
The 5 Kingdoms
  1. Monerans- Microscopic incomplete cells, no nucleus (prokaryptic). Split into two newer kingdoms-  Archaebactria and Eubacteria. (Ex. virus, bacteria)
  2. Protist- Most microscopic single cells, have a nucleus, Eukaryotic, plant, like an animal
  3. Fungi- Most multicellular, no photosynthesis, produce spores, decomposers, (Ex. mushrooms, mildew, mold, etc)
  4. Plants- Most multicellular, photosynthetic
  5. Animals- Most multicellular, no photosynthesis, no cell walls, consumers. 
The 7 Levels of Classification (from largest to smallest)
  1. Kingdom
  2. Phylum
  3. Class
  4. Order
  5. Family
  6. genus
  7. Species
The 8 Levels of Organization (From largest to smallest)
  1. Organisms
  2. Systems
  3. Organs
  4. Tissues
  5. Cells
  6. Organelles
  7. Molecules
  8. Atoms
Why Latin?
There are three reasons why latin is used to name organisms. 
  1. It's a dead language- No one really uses it anymore, that means, it doesn't change.
  2. It's universal- In a way. Because it doesn't change and because a lot of our words have it as root words, people in different cultures can use latin and other people will understand them. 
  3. It doesn't change- yep. 
My biology notes and book

So, did you learn taxonomy yet? Or did you learn anything from this? 


P.S If you need an explanation on anything, feel free to ask!
