Chapter 3.3 Cell Membrane
19
cell membrane:Double-layer of phospholipids that forms a boundary between a cell and the surrounding environment and controls the passage of materials into and out of a cell.
cell wall:rigid structure that gives protection, support, and shape to cells in plants, algae, fungi, and bacteria.
centriole:small cylinder-shaped organelle made of protein tubes arranged in a circle.
chloroplast:organelle composed of numerous membranes that are used to convert solar energy into chemical energy;contains chlorophyll.
cytoplasm:jellylike substance inside cells that contains molecules and in some cells organelles.
cytoskeleton:network of proteins, such as microtubules and microfilaments, inside a eukaryotic cell that supports and shapes the cell.
endoplasmic reticulum:interconnected network of thin, folded membranes that produce, process, and distribute proteins.
eukaryotic cell:cell that has a nucleus and other membrane-bound organelles.
golgi apparatus:stack of flat, membrane-enclosed spaces containing enzymes that process, sort, and deliver proteins(UPS).
lysosome:organelle that contains enzymes and fights off bacteria and viruses.
mitochondria:bean-shaped organelle that supplies energy to the cell and has its own ribosomes and DNA.
nucleus:organelle composed of a double-membrane that acts as the storehouse for most of a cell's DNA.
organelle:membrane-bound structure that is specialized to perform a distinct process within a cell.
phospholipid:molecule that forms a double-layered cell membrane;consists of a glycerol, a phosphate group, and two fatty acid chains.
prokaryotic cell:cell that does not have a nucleus.
receptor:protein that detects a signal molecule and performs an action in response.
ribosome:organelle that links amino acids together to form proteins.
selective permeability:condition or quality of allowing some, but not all, materials to cross a barrier or membrane.
vacuole:organelle that is used to store materials, such as water, food, or enzymes, that are needed by the cell.
