The theory states that all living things are made of up 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

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

a long chain of amino acid molecules; contains carbon, hydrogen, oxygen, nitrogen, and sometimes sulfur

a large macromoleculee that doesnt dissolve in water

a macromolecule made up of one or more sugar molecules, which are composed of carbon, hydrogen and oxygen; usually the bodys major source of energy

a flexible covering that protects the inside of a cell from the environment outside

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 proteins joined togeher that gives a celll its shape and helps it move

Membrane-surrounded component of a eukaryotic cell with a specialized function that's

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

A membrane bound, organelle that uses light energy and makes food a sugar called glucose from water and carbon dioxide in a process called photosynthesis

The movement of substances, the cell membrane without using the cells energy

The movement of substances from an area of higher concentration to a 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 special proteins, called transport proteins

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

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

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

A series of chemical reactions that convert energy include molecules into a usable form of energy called ATP

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

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