1.1.1. Tissue that is organized into...

1.1.1.1. Organs

2. A complex organism has...

3. Cell specialization

3.1. Occurs in multicellular organisms

3.2. Allows cells in one organism to have different roles

3.3. Is possible due to...

3.3.1. Gene expression

3.3.1.1. Even though cells inherit the same genetic code, they only express the parts of the genetic code that they need

4. Cell division

4.1. Two types

4.1.1. Mitosis

4.1.1.1. 1 parent cell splits into two identical daughter cells

4.1.2. Meiosis

4.1.2.1. Sexual reproduction that creates a daughter cell with unique genetic features
