Cells
| Question | Answer |
|---|---|
| What are the three parts of the cell theory? | 1) All living organisms are made of cells 2) All cells come from existing cells 3) The cell is the most basic unit of life |
| What word means "Tiny organ"? | The word "Tiny organ", means organelle |
| What are the three organelles found in a plant cell but nit in an animal cell? | Chloroplasts, cell wall, and a large central vacuole |
| What are the three differences between a prokaryotic cell and a eukaryotic cell? | A eukaryotic cell has a distinct membrane bound organelle, has visible organelles throughout the cell, has a nucleus. The prokaryotic cell doesn't have nucleus, DNA is visible throughout the cell, and has no membrane bound organelle |

| Mitochondrion | generates most of the chemical energy needed to power the cells bio-chemical reactions |
| Ribosomes | Creates proteins for the cell |
| Central vacuole | stores waste products and maintains the pH level of the cell |
| Chloroplasts | converts sunlight into energy by a process called photosynthesis in the plant cell |
| Cell wall | Main barrier for the plant cell |
| Golgi apparatus | helps process and package proteins and lipid molecules |
| what are the five levels of organization from simple to complex | Cells-tissues-organs-organ system-organism |
