Life is organized into 5 levels: Cells Tissues Organs Organ systems Organisms Populations Ecosystems.
What Are Cells?. What are Cells? 1. A cell is a basic unit of structure and function in all living things; therefore, all living things are made up of.

Specialized Cells to Organ Systems. Recall Cell Theory -all living things are made up of cells (one or more) -cells are the smallest unit that can support.

Levels of Organization

Benefits of being multicellular: Larger size

Benefits of being multicellular: Larger size Longer life

Benefits of being multicellular: Larger size Longer life Specialization (particular job; more efficient)

Cell: smallest level

Tissue: a group of cells that perform a common function

4 types of tissues in animals: Nerve Muscle Connective Protective

3 types of tissues in plants: Transport Protective Ground

Organ: a collection of tissues that carry out a specific function of the body

Organ System: a group of organs working together to perform body functions

Organism: a living thing

Remember: in organisms, structure and function are related

Remember: in organisms, structure and function are related Structure: arrangement of the parts (shape)

Remember: in organisms, structure and function are related Structure: arrangement of the parts (shape) Function: job the part does
