Study Notes
- Living things have a hierarchical organization starting from atoms, then molecules, cells, tissues, organs, organ systems, and finally the organism.
- Atoms are the basic unit of matter found in both living and non-living things.
- Molecules are formed by linking atoms together and can be found in living and non-living things.
- Cells are the basic unit of life and contain organelles that carry out specific functions.
- Tissues are formed by multiple cells working together, followed by organs, organ systems, and finally the organism.
This quiz covers the hierarchical organization of living things starting from atoms to molecules, cells, tissues, organs, organ systems, and organisms. It explains the role of each level in the hierarchy and how they contribute to the functioning of living organisms.
