| cytoplasm | the material or protoplasm within a living cell, excluding the nucleus |
| organelle | any of a number of organized or specialized structures within a living cell |
| prokaryotic cell | a cell lacking a true membrane-bound nucleus |
| eukaryotic cell | a cell with a true nucleus; a cell with a nuclear membrane and organelles |
| cytoskeleton | the cytoplasmic network of protein filaments that plays an essiential role in cell movement, shape, and the division |
| nucleus | in physical sience, an atoms central region which is made up of protones and neutrons |
| endoplasmic reticulum | a system of membranes that is found in cells cytoplasm and that assists in the prduction, proccessing, and transport of proteins andin the productions of lipids |
| ribosome | a cell organelle composed of rna and proteins ; the cite of proteins and synthesis |
| golgi apparatus | |
| vesicle | a small cavity or sac that contains materials and eukaradic cell forms when part of the cell membrane sorounds tyhe materials to be take into the cell or transported within the cell |
| mitochondrion | an eukarodic cell, the cell organell that is sourned by too membranes and that is the cite of cellular and resperation, which rpduces atp |
| vacuole | a fluid filled vecule found in the sitoplasm of plant cells or protosomes |
| lysosome | a cell organell that contains conjestive enzymes |
| centriole | an organelle that is active during mitososes |
| cell wall | a riged structure that sourounds the cell membrane and provides support to the cell |
| chloroplast | an orgenell found in plant and alegy cells were photosynthesis accures |
| cell membrane | a phospho lipid layer that covers a cells surface and acts like a barrier between the inside of a cell and the cells invirement |
| phospholipid | a lipid that containes aphosphorus and that is a structual coponet in cell membrane |
| fluid mosaic model | |
| selective permeability | |
| receptor | a specialised sensory nerve that responds to specific types of stimuli |
| passive transport | the movment of substance accross a cell membraene without the use of energy by the cells |
| diffusion | the movement of particles from regions of higher density to regions of lower density |
| concentration gradient | |
| osmosis | the diffusion of water or another sulvent from a more delute solution to a more consentatred through a membraene promedable to the sulvent |
