  6. Notes – Characteristics of Living Things • Living Things Have Cells • All living things are composed of one or more cells. • A __________ is a membrane-covered structure that contains all of the materials necessary for life. • Some organisms are made up of only one cell and some are made up of trillions of cells. In an organism with many cells, different kinds of cells perform __________________ functions. • Living Things Sense and Respond to Change • A ________________ is anything that causes a reaction or change in an organism or any part of an organism. • Homeostasis is the maintenance of a ____________ internal environment. • Responding to External Change - Organisms must _____________ to change in the external environment in order to maintain their homeostasis. • Living Things Reproduce • Organisms make other organisms similar to themselves. • In ______________ reproduction, two parents produce offspring that will share characteristics of both parents. • In ______________ reproduction, a single parent produces offspring that are identical to the parent. • Living Things Have DNA • The cells of all living things contain the molecule deoxyribonucleic acid, or ____. • DNA controls the structure and function of cells. • The passing of traits through _________ is called heredity. • Living Things Use Energy • Organisms use _____________ to carry out the activities of life. • An organism’s _______________ is the total of all of the chemical activities that the organism performs. • Living Things Grow and Develop • All living things, whether they are made of one cell or many cells, ___________ during periods of their lives. • Living things may _____________ and _______________ as they grow.

  7. Read “What’s in an Organism’s Name?” (pages 8-11) Pay close attention to how scientific names are developed.

  8. Use the laptops to find out the scientific name for • Mountain lion • Cougar • Puma
