ny substance that cannot be broken down into simpler substances.

when 2 or more elements chemically combine.

carbohydrates, lipids, proteins, and nucleic acids. Organic compounds must contain carbon.

water. Inorganic compounds DO NOT contain carbon.

energy rich organic compounds made of carbon, hydrogen, and oxygen. Items that have sugar and starches would be carbohydrates. Examples: potatoes, pasta, rice, and bread.

Fats, oils, and waxes. Examples: whole milk, ice cream, and fried foods.

large organic molecules made mostly of carbon, hydrogen, oxygen, nitrogen, and sometimes sulfur. Examples: meat, dairy, fish, nuts, beans.

a group of proteins that helps speed up chemical reactions in living things

Long organic compounds made of carbon, oxygen, hydrogen, nitrogen, and phosphorus. Nucleic acids contain the instructions that carry out all the functions of life. DNA: Shape of the DNA molecule

The genetic material that carries information about an organism and is passed from parent to offspring.

A. Water is needed for most chemical reactions in cells B. Water helps cells keep their shape. C. Water helps cells maintain their temperature D. Water helps cells carry substances in and out of them

When materials go in and out of the cell WITHOUT using energy.

The movement of molecules from an area of high concentration to an area of low concentration.

The movement of WATER molecules across a selectively permeable membrane.

Selectively permeable:

means some substances can cross the membrane while others cannot.

When materials go in and out of the cell using energy.

Moving Large Particles:

. Endocytosis: The cell changes shape and engulfs the particle. 2. Exocytosis: The reverse process, which allows large particles to exit the cell.

Must be organized: Organization – cells specialize to perform specific functions. Levels: cells make tissue, tissue makes organs, organs make organ systems, organ systems make organisms.

3 Types of organisms: multicellular - made of many specialized cells unicellular – made of only 1 cell

Homeostasis - organism’s response to the environment that keeps conditions suitable for life

Reproduction: asexual - all or part of the organism is used to make a new organism, offspring are genetically identical to parent sexual – two cells from different individuals combine to form the first cells of a new organism, traits are inheritete
