1. Atoms → Molecules → Cells → Tissues → Organs → Organism
Warmup 1/30
List the correct order of the organization of life:
Atoms → Molecules → Cells → Tissues → Organs → Organism

2. Weird Organism of the Day
Common Name: Dragon Blood Tree
Scientific Name: Dracaena cinnabari

6. Organization of Life
Atoms
Molecules
Cells
Tissues
Organs
Organism

7. The smallest particle of an element
Atoms
The smallest particle of an element
Examples: Oxygen, Hydrogen, Carbon

8. Molecules A group of atoms bonded together
Examples of small molecules: Water, carbon dioxide
Examples of macromolecules: protein, DNA
Protein Molecule

9. Macromolecule
Thousands of molecules linked together to form one LARGE macromolecule (macro= large)

10. Cells The most basic unit of life One of the characteristics of life
Many types, shapes, and sizes
Some living things are a single cell!

11. Made up of a group of cells that are all of the same type
Tissues
Made up of a group of cells that are all of the same type
Examples: Skin tissue, muscle tissue

12. Organs Tissues that work together to serve a specific function or job
Examples: Heart, lungs, stomach, vascular (in plants)

13. Organism
Living being such as a plant, animal, or single-celled life form
Multicellular organisms are made up of organs

14. Population
Group of organisms of the same species that live in a particular area.

15. Community
Groups of populations of all species living in a particular area and interacting with each other.

16. Ecosystem
Biotic and Abiotic factors interacting in a particular area.

17. Biosphere
All of the ecosystems and all of the living things on the earth.
