Levels of Organization
Why do we need to learn about levels of organization?
Helps us to understand how our world fits together
Helps us to organize the structures of living systems and how they all work together 1. Organelles - “ little organs”
- Small structures inside of a cell that perform a specific function.
- Examples include mitochondria, nucleus, and Golgi body 2. Cell- Basic unit of structure & function in life. Cells are the building blocks of all living things. 3. Tissue - A group of the same kind of cells working together for a specific purpose 4. Organs - A part of an organism made up of tissues that do a specific job. 5. Organ Systems - A group of organs that work together for a specific job. 9. Organism - Any living thing.
10. Population -A group of the same organism living together.
- This word is often used to describe the size of the group. 11. Community- Several populations living together and interacting in...
