| Question | Answer |
|---|---|
| The portion of the cell outside the nucleus | cytoplasm |
| the structures within the eukaryotic cell that perform important cellular functions are known as | organelle |
| contains nearly all the cell's DNA and with it the coded instructions for making proteins and other important molecules | nucleus |
| parts of the nucleus | chromatin, nucleolus, nuclear envelope, and nuclear pores |
| surrounds the nucleus and is composed of two membranes | nuclear envelope |
| granular material in the nucleus | chromotin |
| contained by most nuclei | nucleolus |
| small particles of RNA and protein found throughout the cytoplasm; produce proteins | ribosomes |
| where lipid components of the cell membrane are assembled, along with the proteins and other materials that are exported from the cell | endoplasmic reticulum |
| Proteins produced in the rough ER move into? | golgi apparatus |
| modifies, sorts, and packages proteins and other materials from the endoplasmic reticulum for the storage in the cell or secretion outside the cell | golgi apparatus |
| small organelles filed with enzymes and they break down lipids, carbohydrates, and proteins into small molecules that can be used by the rest of the cell | lysosomes |
| contained in some cells and they store materials such as water, salts, proteins, and carbohydrates | vacuoles |
| convert the chemical energy stored in the food into compounds that are more convenient for cell use | mitochondria |
| capture energy from the sunlight and convert it into chemical energy in a process called photosynthesis | chloroplasts |
| give eukaryotic cells their shape and internal organization | cytoskeleton |
| located near the nucleus and help to organize cell division | centrioles |
| in the nucleus of the cell, DNA is usually visible as | granular material called chromatin |
| two functions of vacuoles are storing materials and helping to | maintain homeostasis |
| chloroplasts are found in the cells of | plants and some other organisms |
| functions of golgi apparatus | modify proteins, sort proteins, package proteins |
| function of the cytoskeloton | assists in movement of some cells from the one place to another |
