| The following object belongs to which level of organization: heart | organ |
| The following object belongs to which level of organization: nervous system | organ system |
| The following object belongs to which level of organization: gorilla | organism |
| What is the function of the mitochondria? | Converts energy for cell use. |
| What types of cells contain one very large central vacuole? | Plant Cells |
| What piece of science equipment is used to observe cells? | Microscope |
| What is the function of the cell wall? | Provides structure for plant cells. |
| Why do animal cell NOT need a cell wall? | Animals get their structure from bones. |
| Why do animal cells NOT need chloroplast? | Animal cells get their energy from outside sources. |
| Which organelles can be identified only in a plant cell? | Cell Wall, Chloroplast, Large Central Vacuole |
| The fluid surrounding the cell organelles is called what? | Cytoplasm |
| Which organelles allows substances to enter and exit the cell? | Cell Membrane |
| What is the function of the nucleus? | Controls cell activity |
| What can the nucleus be compared to in a school and why? | Principal because he/she controls the schools activity just like the nucleus controls the activity in a cell. |
| What is the function of a chloroplast? | Conducts photosynthesis in plant cells. To convert radiant energy from the sun into chemical energy through phtosynthesis. |
| Why do we use models to study cells? | It makes it easier to see something that is microscopic. |
| What is the definition of a cell? | The smallest structural and functional unit of an organism |
| What is the definition of an organelle? | The smallest structural and functional unit of an organism. |
