Why do you think that bee species outnumber mammal and bird species combined?
The bees reproduce faster and do not need as much food or space to stay alive

3. How are organisms classified?
Linnaeus classified organisms as plants or animals.
Do you think he knew about microscopic organisms, such as bacteria?
No, because microscopes had not been invented yet!

4. Does King Phillip Come Over For Good Spaghetti?

5. How are organisms classified?
Classification based on:
-their cell type
-ability to make food
-# of cells in their bodies

6. 3 Domains
Bacteria
Unicellular prokaryotes (unicellular organisms whose cells lack a nucleus)
Nucleic acids (DNA) are not in a nucleus
Some autotrophs, some heterotrophs

7. 3 Domains 2. Archaea Unicellular prokaryotes Live in harsh conditions
Some autotrophs, some heterotrophs
Different chemical makeup and cell structure than bacteria

8. 3 Domains
3. Eukarya
Eukaryotes (organisms with cells that contain nuclei)
Divided into 4 kingdoms: protists, fungi, plants, animals

9. Brainpop: Kingdom

10. Protist Kingdom
-Sometimes called the “odds and ends” kingdom because protists vary so much
-Some autotrophs, some heterotrophs
-Most are unicellular, but some (like seaweed) are multicellular

11. Fungi Kingdom -Mushrooms, molds, and mildew
-Most are multicellular, but some (like yeast) are unicellular
-Mostly found on land
-Heterotrophs (decomposers: feed by absorbing nutrients from dead or decaying organisms)

12. Plant Kingdom -Multicellular eukaryotes -Autotrophs
-Provide food for most heterotrophs

13. Animal Kingdom -Multicellular eukaryotes -Heterotrophs
-Have different adaptations that allow them to locate food, capture it, eat it, and digest it

14. Apply It! Page 24 There are nuclei present.
Protists Fungi Plants Animals
You can count more than one cell.
The organism cannot make its own food.
Protists Fungi Plants Animals
The organism gets nutrients from dead organisms.
Protists Fungi Plants Animals
Other members of this kingdom can be unicellular.

15. To which domains do only prokaryotes belong?
Review Questions
To which domains do only prokaryotes belong?
Bacteria and Archaea
How could domain Eukarya be further divided?
Into the kingdoms Protists, Fungi, Plants, and Animals

16. To which domain and kingdom do you belong?
Domain: eukarya Kingdom: animal
To which domain and kingdom does this organism belong?
Domain: eukarya Kingdom: fungi

17. What 3 characteristics can a protist share with a plant?
Review Questions
What 3 characteristics can a protist share with a plant?
Cells contain a nucleus (eukaryotes), are multicellular, and are autotrophs
