Question	Answer
cell wall	the outer layer of a cell, esp the structure in plant cells that consists of cellulose, lignin, etc, and gives mechanical support to the cell
cell membrane	a very thin membrane, composed of lipids and protein, that surrounds the cytoplasm of a cell and controls the passage of substances into and out of the cell
cellulose	an inert carbohydrate, (C 6 H 10 O 5 )the chief constituent of the cell walls of plants and of wood, cotton, hemp, paper, etc.
glucose	a sugar, C 6 H 12 O 6 , having several optically different forms, the common dextrorotatory form
homeostasis	the tendency of a system, especially the physiological system of higher animals, to maintain internal stability, owing to the coordinated response of its parts to any situation or stimulus that would tend to disturb its normal condition or function.
selectively permeable	being able to be broken into smaller forms
lipid	any of a group of organic compounds that are greasy to the touch, insoluble in water, and soluble in alcohol and ether:
phospholipid	any of a group of fatty compounds, as lecithin, composed of phosphoric esters, and occurring in living cells.
hydrophobic	having little or no affinity for water.
hydrophilic	having a strong affinity for water.
fluid mosaic model	A model that describes the structure of cell membranes. In this model, a flexible layer made of lipid molecules is interspersed with large protein molecules that act as channels through which other molecules enter and leave the cell.
amino acids	building blocks from which proteins are constructed.
protein	any of numerous, highly varied organic molecules constituting a large portion of the mass of every life form and necessary in the diet of all animals and other nonphotosynthesizing organisms, composed of 20 or more amino acids linked in a genetically con
