Exploring and Classifying Life Chapter 1

Characteristics of Life: 1. Living things are made of cells. 2. Living things use energy. 3. Living things grow, develop and adapt. 4. Living things respond to their environment. 5. Living things reproduce.

All Living Things are Made of Cells!! • Cell – the smallest unit of an organism that carries out the function of life. • Cells ONLY come from other cells!

Living Things use Energy All of our energy comes from the sun!

Living things grow, develop and adapt. • Living things grow in size. • Living things grow in complexity. • Living things adapt, or change as they grow.

Living Things Respond to their Environment • Stimulus- Signal to which an organism reacts. • Response- an action caused by a stimulus.

Living Things Reproduce Reproduction- the process by which living things give rise to the same kind of living things.

Made of Cells Use Energy Grow, develop and adapt Living Things Respond Reproduce

What do Living Things Need? ? • Living space • Water • Food

Classification • The grouping of things according to similar characteristics. • We put objects into groups based on how similar they are.

Taxonomy • The science of classification! • Aristotle- an ancient Greek philosopher who classified organisms as plants or animals.

Carolus Linnaeus – Swedish naturalist that grouped organisms by similar structure. – He used Binomial Nomenclature- two part naming system. – He identified creatures by two names: genus and species.

Modern Classification • Modern scientists use: – similarities – fossils & – genetics to group organisms today.

Pneumonic Device • King Phillip came over for good spaghetti. • Kingdom, Phylum, Class, Order, Family, Genus, Species.

Modern Classification • Kingdoms are the largest and most general category. • While species are the smallest and most specific. • Organisms belonging to the same species can reproduce offspring.

Scientific Names • Using common names among scientists can cause confusion. • Linnaeus helped solve this problem by developing binomial nomenclature.
