Six Characteristics of Living Things
Living things are made of 1 or more cells the smallest unit can perform all life
functions has all the materials
necessary for life

Six Characteristics of Living Things
Living things sense and respond to change Stimulus-anything that causes a reaction or
change in an organism Homeostasis-maintaining a constant internal
state in a changing environment

Six Characteristics of Living Things
Living things reproduce Asexual reproduction - single parent produces
identical offspring Sexual reproduction - two parents produce
offspring

Six Characteristics of Living Things
Living things have DNA DNA- controls structure and function of cells Heredity - passing of traits from one generation
to the next

Six Characteristics of Living Things
Living things use energy Metabolism - total of all the chemical activities
the organism performs

Six Characteristics of Living Things
Living things grow and develop - all living things get larger and change as they grow (unicellular organisms divide)

Necessities of Life
Water - 70% of our bodies are water Air - oxygen and carbon dioxide used by a
number of organisms Shelter - some organisms stay in one place,
others migrate Food - used for energy

Who Eats What?
Producers - plants use light of sun to make sugar glucose from water and carbon dioxide
Consumers - eat plants and other animals, cannot make their own food
Decomposers - break down the nutrients in dead plants and animals

Organic Molecules
Proteins - made of amino acids, build structures, do certain jobs, and speed up chemical reactions (enzymes)
Carbohydrates - energy source and storage

Organic Molecules
Lipids Phospholipids create the cell membrane Fats and oils-store energy for use at later time

Organic Molecules
ATP- adenosine triphosphate-energy molecule in cells, made when cells break down glucose (sugar) from plants
Nucleic Acids- DNA and RNA; responsible for the creation of proteins that control cell function
