| What is differentiation? | Organisms can have cells that specialize in function. |
| In what kind of organism (unicellular or multicellular) does this occur? Differentiation | Multicellular |
| What is a cell? | -The basic unit of life. - Smallest living level of organization. |
| What is an organelle? | - Largest non-living level of organization. |
| Cell Membrane | - Both cells - Controls what goes in and out of the cell. |
| Cell Wall | - Provides structural strength and support to plant cells. |
| Cytoskeleton | - Both cells - Supports and shapes the cell, helps position and transport organelles, provides strength, and aids cell movement. |
| Cytoplasm | - Both cells - Responsible for holding the components of the cell, protecting them from damage. |
| Smooth ER | -Both cells -Produces lipids and acts as a transport system. |
| Rough ER | -Both cells -Produces proteins and acts as a transport system. |
| Nucleus | -Both cells - Controls cell Function |
| Nucleolus | - Both cells - Inside nucleus - Produces ribosomes |
| Nuclear Envelope | - Both cells - Separates the contents of the nucleus from Cytoplasm providing structure for the nucleus. |
| Ribosomes | - Both cells - Produces proteins |
| Lysosome | - Both cells - Break down Food, waste, etc in a cell. |
| Vacuole | - Both Cells - Stores Food, proteins, water, etc. |
| Central Vacuole | -Plant Cells - Stores salts, minerals, nutrients, proteins, playing important structural support. |
| Golgi Body | -Both Cells - Packages proteins for transport. |
| Mitochondria | -Both cells -Produces energy for the cells |
| Chloroplast | - Plant cells - Produces energy in the form of sugar. |
| Cilia | - Both cells - Many hairs around a cell that help with movement. |
| Flagella | -Both cells -One to three long tails that help cells move. |
