The theory that all living things are made up of one or more cells, the cell is the smallest unit of life, and all new cells come from preexisting cells

Substance that forms from joining many small molecules together

A macromolecule that forms when long chains of molecules called nucleotides join together

A long chain of animo acid molecules; contains carbon, hydrogen, oxygen, nitrogen, and sometimes sulfur

A large macromolecule that does not dissolve in water

A macromolecule made up of one or more sugar molecules, which are composed of carbon, hydrogen, and oxygen; usually the body's major source of energy

A flexible covering that protects the inside of a cell from the enviroment outside the cell

A stiff structure outside the cell membrane that protects a cell from attack by viruses and other harmful organisms

The liquid part of a cell inside the cell membrane; contains salts and other molecules

A network of threadlike proteind joined together that gives a cell its shape and helps it move

Membrane-surrounded component of eukaryotic cell with a specialized function

Part of eukaryotic cell that directs cell activity and contains genetic information stored in DNA

A membrane-bound organelle that uses light energy and makes food - a sugar called gluclose - from water and carbon dioxide in a process known as photpsynthesis

The movement of substances through a cell membrane without using the cells energy

The movement of substances from an area of higher concentration to an area of lower concentration

The diffusion of water molecules only through a membrane

Facilitated Diffusion

The process by which molecules pass through a cell membrane using psecial proteind called transport proteins

The movement of substances through a cell membrane using the cells energy

The process during which a cell takes in a substance by surrounding it with the cell membrane

The process during which a cells vesicles release their contents outside the cell

The series of chemical reactions that convert the energy in food molecules into a usable form of energy called ATP

A process by which glucose, a sugar, is broken down into smaller molecules

A reaction that eukaryotic and prokaryotic cells can use to obtain enegy from food whe oxygen levels are low

A series of chemical reactions that convert light energy, water, and CO2 into the food-energy molecule glucose and give off oxygen
