| LYSOSOMES | the organelle involved in the breakdown of foreign material and debris using digestive enzymes. |
| ENZYME-SUBSTRATE COMPLEX | the substrate bonds with the enzyme active site and forms a structure together |
| DEOXYRIBONUCLEIC ACID (DNA) | a molecule that carries the genetic instructions used in the growth, development, functioning and reproduction of all known living organisms |
| PHOTOSYNTHESIS | chemical process used in plants to convert energy in the form of sunlight into chemical energy in the form of sugars or other carbohydrates. |
| RESPIRATORY SYSTEM | the system is involved in the intake and exchange of oxygen and carbon dioxide between an organism and the environment. |
| CIRCULATORY SYSTEM | organ system that permits blood to circulate and transport nutrients, oxygen, carbon dioxide, hormones, and blood cells to and from the cells in the body. |
