| cell membrane | outer covering of the cell, let good things in and keep bad things out |
| chromosome | made of DNA; direct the cells' activities, pass on the traits to new cells |
| nucleolus | little nucleus inside nucleus, plays an important role in making RNA |
| nucleus | the cell's control center, "the boss" inside a cell, chromosomes and DNA live here. Center of the cell |
| nuclear membrane | surround nucleus, holds and protects the nucleus |
| endoplasmic reticulum (ER) | a network of tubes inside a cell, transport proteins |
| mitochondria | powerhouse of cells, break down food, supply energy for cells |
| cytoplasm | clear, jellylike liquid in a cell |
| ribosomes | make proteins |
| vacuoles | store food, water and waste products |
| lysosomes | break down large food molecules; digest things in the cytoplasm |
| organelles | little organs inside a cell, like mitochondria, lysosomes... |
| DNA | stores the information for making proteins; a type of nucleic acid |
| RNA | reads the DAN message and guides the protein-making process. It carries the message and leaves the nucleus to guide protein making. |
