A fairly rigid structure located outside the plasma membrane that provides additional support and protection.

The flexible boundary between the cell and its environment, to allow a steady supply of nutrients(glucose, amino acids, lipds, etc.) to come into the cell no matter what the external conditions are.

A glucose polymer that forms the cell walls of plants and gives plants structural support.

A monosaccharide sugar the blood that serves as the major energy source of the body; it occurs in most plant and animal tissue.

Organism's regulation of it's interval environment to maintain conditions suitable for survival.

Selectively Permeable

A process in which a membrane allows some molecules to pass through while keeping others out.

Large organic compounds made mostly of carbon and hydrogen with a small amount of oxygen, are insoluble in water and used by cells for energy storage, insulation, and protective coatings. Ex. fats, oils waxes, etc.

Has a glycerol backbone, two fatty acid chains, and a phosphate group. The plasma membrane is composed of a phospholipid bilayer, which has two layers of phospholipids back-to-back.

Readily absorbing or dissolving in water.

The model of the plasma membrane.

Basic building blocks of of protein molecules.

Large, complex polymer essential to all life; provides structure for tissues and organs and helps carry out cell metabolism.

Term	Definition
Cell Wall	A fairly rigid structure located outside the plasma membrane that provides additional support and protection.
Cell Membrane	The flexible boundary between the cell and its environment, to allow a steady supply of nutrients(glucose, amino acids, lipds, etc.) to come into the cell no matter what the external conditions are.
Cellulose	A glucose polymer that forms the cell walls of plants and gives plants structural support.
Glucose	A monosaccharide sugar the blood that serves as the major energy source of the body; it occurs in most plant and animal tissue.
Homeostasis	Organism's regulation of it's interval environment to maintain conditions suitable for survival.
Selectively Permeable	A process in which a membrane allows some molecules to pass through while keeping others out.
Lipid	Large organic compounds made mostly of carbon and hydrogen with a small amount of oxygen, are insoluble in water and used by cells for energy storage, insulation, and protective coatings. Ex. fats, oils waxes, etc.
