The basic unit of structure and function in living things

An instrument that makes small objects

A widely accepted explanation of the relationship between cels and living things

A rigid supporting layer that surrounds the cells of plants and some other organisms

A thin, flexible barrier that surrounds a cell and controls which substances pass into and out of the cell

In cells, a large oval organelle that contains the cell's genetic material in the form of DNA and controls many of the cell's activities

A tiny cell structure that is composed of different kinds of tissues that work together

A small grain-shaped organelle in the cytoplasm of a cell that produces proteins

An organization that forms a maze of passageways in which proteins and other materials are carried from one part of the cell to the other to another

An organization in a cell that receives proteins and other newly formed materials from the endoplasmic reticulum packages them, and distributes them to other parts of the cell

A sac-like organelle that stores water, food, and other materials

An organelle in the cells of plants and some other organisms that captures energy from sunlight and changes it to an energy form that cells can use in making food.

A cells organelle which contains chemicals that break down larger food particles into smaller ones and that can be used by the rest of the cell.

A group of similar cells that perform a specific function.

A body structure that is composed of different kinds of tissues that work together.

A group of organs that work together to perform a major function.

A pure substance that cannot be broken down into other substances by chemical or physical means.

A substance made of two or more elements chemically combined in a specific ratio, or proportion.

An energy rich organic compound, such as a sugar or a starch, that is made up of the elements carbon, hydrogen, and oxygen.

An energy-rich organic compound, such as a fat, oil, or wax, that is made of carbon, hydrogen, and oxygen.

Large organic molecule made of carbon, hydrogen, oxygen, nitrogen, and sometimes sulfur.

A type of protein that speeds up a chemical reaction in a living thing.

A very large organic molecule made of carbon, oxygen, hydrogen, nitrogen, and phosphorus, that contains the instructions for cells need to carry out all the functions of life.

Deoxyribonucleic acid, the genetic material that carries information about an organism and is passed from parent to offspring.
