cell vocab
| Question | Answer |
|---|---|
| cell | The cell is the basic structural and functional unit of all forms of life. Every cell consists of cytoplasm enclosed within a membrane |
| osmosis | Osmosis provides the primary means by which water is transported into and out of cells. |
| cell therory | Cell theory is a scientific theory first formulated in the mid-nineteenth century, that living organisms are made up of cells. |
| cell wall | A cell wall is a structural layer that surrounds some cell types, found immediately outside the cell membrane. |
| cell membrane | The cell membrane controls the movement of substances in and out of a cell, being selectively permeable to ions and organic molecules |
| nucleus | a central structure that acts as the core or control center |
| organelle | They include structures that make up the endomembrane system |
| ribosome | Ribosomes are macromolecular biological machines found within all cells that perform messenger RNA translation. |
| nucleic acid | Nucleic acids are chemical compounds that are found in nature. |
| selectively permeable | Semipermeable membrane is a type of synthetic or biologic, polymeric membrane that allows certain molecules or ions to pass through it by osmosis. |
| cytoplasm | The cytoplasm is all the material within a eukaryotic or prokaryotic cell, enclosed by the cell membrane, including the organelles and excluding the nucleus . |
| mitochondria | A mitochondrion ( pl. mitochondria) is an organelle found in the cells of most eukaryotes, such as animals, plants and fungi. Mitochondria have a double |
| Endoplasmic reticulum | The endoplasmic reticulum (ER) is a part of a transportation system of the eukaryotic cell, and has many other important functions such as protein folding. |
| golgi apparatus | The Golgi apparatus also known as the Golgi complex, Golgi body, or simply the Golgi, is an organelle found in most eukaryotic cells. |
| chromoplast | Chromoplasts are plastids, heterogeneous organelles responsible for pigment synthesis and storage in specific photosynthetic eukaryotes. |
| lysosome | A lysosome is a membrane-bound organelle that is found in all mammalian cells, with the exception of red blood cells (erythrocytes). |
| DNA | Deoxyribonucleic acid (; DNA) is a polymer composed of two polynucleotide chains that coil around each other to form a double helix. |
| passive transport | Passive transport is a type of membrane transport that does not require energy to move substances across cell membranes. |
| active transport | 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 | 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 . |
| tissue | In biology, tissue is an assembly of similar cells and their extracellular matrix from the same embryonic origin that together carry out a specific function. |
| organ | In a multicellular organism, an organ is a collection of tissues joined in a structural unit to serve a common function. |
| organ system | An organ system is a biological system consisting of a group of organs that work together to perform one or more bodily functions. |
| endocytosis | Endocytosis ... Endocytosis is a cellular process in which substances are brought into the cell. |
| exocytosis | Exocytosis is the process by which a large amount of molecules are released; thus it is a form of bulk transport. |
