| Question | Answer |
|---|---|
| cell | the basic unit of all forms of life |
| cell theory | a fundamental concept of biology that states that all living things are composed of cells,that cells are the basic units of structure and function in living things,and that new cells are produced from existing cells. |
| nucleus | a structure that contains the cell's genetic material in the form of DNA |
| eukaryote | an organism whose cell contains a nucleus |
| prokaryote | a unicellular organism that lacks a nucleus |
| cytoplasm | the fluid portion of the cell outside the nucleus |
| organelle | a specialized structure that preforms important cellular functions within a eukaryotic cell. |
| vacuole | the cell organelle that stores materials such as water,salts,proteins,and carbohydrates |
| lysosome | the cell organelle that breaks down lipids,carbohydrates,and proteins into small molecules that can be used by the rest of the cell |
| cytoskeleton | the network of protein filaments in eukaryotic cell that gives the cell its shape and internal organization and is involved in movement |
| ribosome | a cell organelle consisting of RNA and protein found throughout the cytoplasm ina cell;the site of protein synthesis |
| endoplasmic reticulum | the internal membrane system found in eukaryotic cells;the place where lipid components of the cell membrane are assembled |
| golgi apparatus | an organelle in cells that modifies,sorts,and packages proteins and other materials from the endoplasmis reticulum for the storage in the cell or release outside the cell |
| chloroplast | an organelle found in cells of plants and some other organisms that captures the energy from sunlight and converts it into chemical. |
| mitochondrion | a cell organelle that converts the chemical energy stored in food into compounds that are more convenient for the cell to use. |
| lipid bilayer | a flexible double-layered sheet that makes up the cell membrane and forms a barrier between the cell and its surroundings. |
| what is the function of the cell membrane? | the cell membrane keeps track of what enters and leaves the cell and also protects and suports the cell. |
| diffusion | the process by which particles tend to move from an area where they are more concentrated to an area where they are less concentrated. |
| facilated diffusion | the process of diffusion in which molecules pass across the membrane through cell membrane channels |
| osmosis | the diffusion of water through a selectively permeable membrane. |
| osmotic pressure | the pressure that must be applied to prevent osmotic movement across a selectively permeable membrane. |
| what is passive transport? | the movement of materials across the cell membrane without losing energy. |
| active transport | the movement of materials from an area of lower concentration to an area of higher concentration.active transport requires energy. |
| homeostasis | the relatively constsnt internal physical conditions that organisms maintain. |
| tissue | a group of similar cells that perform particular function |
| organ | a group of tissues that work together to perform closely related functions. |
