| Cell | The basic unit of all living things |
| Nucleus | Part of a cell that functions in controlling activities of the cell. |
| Cell wall | Part of a cell found only in plant cells and adds a layer of protection. |
| Vacuoles | Part of a cell that provides storage for excess materials such as wastes |
| Ribosomes | Part of the cell that makes proteins. |
| Plasma membrane | Part of the cell maintains homeostasis in the cell allowing substances in and out. |
| Mitochondria | The energy for the cell is produced in this part of a cell. |
| Chloroplasts | The organelles where photosynthesis takes place in the plant cell. |
| Prokaryotic | Type of cells that do not have membrane bound organelles (ex. bacteria). |
| Eukaryotic | Type of cells that have membrane bound organelles (ex. animal or plant cell). |
| Homeostasis | The process of maintaining a constant internal environment. |
| Passive transport | Transport that does not require energy because particles are moving from areas of high concentration to areas of low concentration. |
| Diffusion and osmosis | Examples of passive transport. |
| Active transport | Transport that requires energy because particles are moving from areas of low concentration to areas of high concentration. |
| Mitosis | The process of cell division in body cells (somatic cells) in which diploid cells are produced. |
| Meiosis | The process of cell division in gametes (sex cells) in which haploid cells are produced. |
| Zygote | A fertilized egg that is the result of the fusion of a sperm and an egg. |
| Gametes | Sex cells |
| Somatic cells | Body cells |
