Matter

Matter - What Things are Made Of

  • Living things have special structures that perform specific functions. Some are made in the body; some must be acquired.

  • Water makes up the majority of an organism's mass.  It is used to transport molecules and heat throughout the body.

  • Organic Molecules are made by living things

    • Carbohydrates provide short term energy and make up plant cell walls

    • Lipids provide long term energy, insulation, and waterproof barriers

    • Proteins make up an organism's unique structure and enzymes (a type of protein) enable the cells to perform specific functions.  So proteins are everything an organism is and does.

    • Nucleic Acids carry information about making proteins, so DNA controls everything an organism is and does.

  • On a larger scale, the atoms that make up these molecules cycle through various parts of the ecosystem.
