| 1799733 | organelle | specialized structure that performs important cellular functions within a eukaryotic cell | 0 | |
| 1799734 | cytoplasm | material inside the cell membrane—not including the nucleus | 1 | |
| 1799735 | nucleus | contains nearly all the cell's DNA and with it the coded instructions for making proteins and other important molecules | 2 | |
| 1799736 | nuclear envelope | layer of two membranes that surrounds the nucleus of a cell | 3 | |
| 1799737 | chromatin | granular material visible within the nucleus; consists of DNA tightly coiled around proteins | 4 | |
| 1799738 | chromosome | threadlike structure within the nucleus containing the genetic information that is passed from one generation of cells to the next | 5 | |
| 1799739 | nucleolus | small, dense region within most nuclei in which the assembly of proteins begins | 6 | |
| 1799740 | ribosome | small particle in the cell on which proteins are assembled; made of RNA and protein | 7 | |
| 1799741 | endoplasmic reticulum | internal membrane system in cells in which lipid components of the cell membrane are assembled and some proteins are modified | 8 | |
| 1799742 | Golgi apparatus | stack of membranes in the cell that modifies, sorts, and packages proteins from the endoplasmic reticulum | 9 | |
| 1799743 | lysosome | cell organelle filled with enzymes needed to break down certain materials in the cell | 10 | |
| 1799744 | vacuole | cell organelle that stores materials such as water, salts, proteins, and carbohydrates | 11 | |
| 1799745 | mitochondrion | cell organelle that converts the chemical energy stored in food into compounds that are more convenient for the cell to use | 12 | |
| 1799746 | chloroplast | organelle found in cells of plants and some other organisms that captures the energy from sunlight and converts it into chemical energy | 13 | |
| 1799747 | cytoskeleton | network of protein filaments within some cells that helps the cell maintain its shape and is involved in many forms of cell movement | 14 | |
| 1800024 | centriole | one of two tiny structures located in the cytoplasm of animal cells near the nuclear envelope | 15 |
