Copy of Characteristics Concept Map (colored paper) The Science of Biology Chapter 1 What is Biology? The study of life (Greek word bios, meaning life and logos, meaning study Properties of Life What characteristics do living creatures have in common? Biology: Video Living creatures GROW & DEVELOP • Change over an individual’s life time – get bigger – mature • so they can reproduce Living creatures use ENERGY • Metabolism – all the reactions your body performs to make & use energy • eating & digestion & elimination of waste • synthesis = building mitochondria • cellular respiration = making energy Living creatures RESPOND AND MOVE • Respond to internal changes – Homeostasis • maintaining balanced conditions inside the body • Respond to external changes Living creatures REPRODUCE • Make the next generation Asexual-single parent Sexual- two parents (sperm and egg) Living Creatures are made of CELLS • All living organisms are made up of cells. • Can be made up of one cell (unicellular) or trillions of cells (multicellular). Living creatures are ORGANIZED • All made of the same collection of chemicals, but we are organized as… – organelles & cells • plant cells & animal cells plant cell animal cell Living creatures are ORGANIZED • All made of the same collection of chemicals, but we are organized as… – organs & organ systems • respiratory, circulatory, digestive, etc. Living creatures have DNA • Has a set genetic code that is passed down from parent to offspring • directions for inheritance • DNA AND RNA Living creatures EVOLVE • Living things adapt and can evolve (change of time) Characteristics of Life: Video Complete Characteristics of Life CONCEPT MAP with 11:00 appointment ORGANIZATION • ORGANISM-anything that possesses all of these characteristics of life. • SPECIES-organism that can interbreed and produce fertile offspring (if not leads to EXTINCTION) Levels of ORGANIZATION Organization: Video Levels of Biological Organization Biosphere-Earth Scientific Inquiry: Thinking Like a Scientist • Scientists collect data by making careful observations. • An observation is a record or note made by studying something using the senses. • Data is information gathered through observations. • An inference is a deduction or assumption based on observations and prior knowledge.
