| Question | Answer |
|---|---|
| cell | basic structural and functional unit of all forms of life. |
| Osmosis | provides the primary means by which water is transported into and out of cells. |
| Cell Theory | Is a scientific theory first formulated in the mid-nineteenth century. |
| Cell Wall | a structural layer that surrounds some cell types, found immediately outside the cell membrane. It can be tough, flexible and more. |
| Cell Membrane | controls the movement of substances in and out of a cell, being selectively permeable to ions and organic molecules. |
| Nucleus | a membrane-bound organelle found in eukaryotic cells. |
| Organelle | a specialized sub-unit, usually within a cell, that has a specific function. |
| Ribosome | macromolecular biological machines found within all cells that perform messenger RNA translation. |
| Nucleic Acid | chemical compounds that are found in nature. They carry information in cells and make up genetic material. |
| Selectively Permeable | with the passage of molecules controlled by facilitated diffusion, passive transport or active transport |
| Cytoplasm | all the material within a eukaryotic or prokaryotic cell, enclosed by the cell membrane, including the organelles[1] and excluding the nucleus in eukaryotic cells. |
| Mitochondria | an organelle found in the cells of most eukaryotes, such as animals, plants and fungi. |
| Endoplasmic Reticulum | a part of a transportation system of the eukaryotic cell, and has many other important functions such as protein folding. Mitochondrion. |
| Golgi Apparatus,,,,,,,,,, | also known as the Golgi complex, Golgi body, or simply the Golgi, is an organelle found in most eukaryotic cells. |
| Chlorplast | a type of organelle known as a plastid that conducts photosynthesis mostly in plant and algal cells |
| Lysosome | a membrane-bound organelle that is found in all mammalian cells, with the exception of red blood cells (erythrocytes). |
| Lysosome | a membrane-bound organelle that is found in all mammalian cells, with the exception of red blood cells (erythrocytes). |
| DNA | a polymer composed of two polynucleotide chains that coil around each other to form a double helix. |
| Passive Transport | a type of membrane transport that does not require energy to move substances across cell membranes. |
| Active Transport | is the movement of molecules or ions across a cell membrane from a region of lower concentration to a region of higher concentration. |
| Diffusion | is the net movement of anything (for example, atoms, ions, molecules, energy) generally from a region of higher concentration to a region of lower concentration. |
| Tissue | an assembly of similar cells and their extracellular matrix from the same embryonic origin that together carry out a specific function. |
| Organ | a collection of tissues joined in a structural unit to serve a common function. |
| Organ System | a biological system consisting of a group of organs that work together to perform one or more bodily functions. |
| Endocytosis | a cellular process in which substances are brought into the cell. |
| Exocytosis | the process by which a large amount of molecules are released; thus it is a form of bulk transport. |
