|---|---|
| Cell | Is the basic membrane that contains the molecules of life. |
| Osmosis | Is the passage of water or other liquids through a membrane. |
| Cell theory | Is the scientific theory of biology. |
| Cell wall | It is a specialized form of extracellular matrix that surrounds every cell of a plant. |
| Cell membrane | Is the thin layer that surrounds every living cell, delimiting the cell from the environment around it. |
| Nucleus | Is a specialized structure occurring in most cells. |
| Organelle | Is any of the specialized structures within a cell that perform a specific function. |
| Ribosome | Is a particle that is present in large numbers in all living cells. |
| Nucleic acid | Is a naturally occurring chemical compound that serves as the main information-carrying molecule. |
| Selectively permeable | Is a biological or synthetic barrier that allows specific molecules and ions to pass through while blocking others. |
| Cytoplasm | Is the semifluid substance of a cell that is external to the nuclear membrane. |
| Mitochondria | Is a membrane-bound organelle found in the cytoplasm. |
| Endoplasmic reticulum | Is a continuous membrane system that forms a series of flattened sacs within the cells. |

| Lysosome | Is a subcellular organelle that is found in nearly all types of eukaryotic cells. |
| DNA | Is the organic chemical of complex molecular structure. |
| Passive transport | Is the changes that the proteins undergo in order to facilitate diffusion. |
| Active transport | In which ions and water are pumped into and out of living cells. |
| Diffusion | Is the process resulting from random motion of molecules by which there is a net flow. |
