CHARACTERISTICS OF LIFE What it means to be living? WHAT IS BIOLOGY? Biology is the study of all ______________________ things Living things are called _____________________ Organisms include bacteria, protists, fungi, plants, & animals ALL LIVING THINGS SHARE COMMON CHARACTERISTICS 1. Basic Unit is the ___________________ 2. They ______________________ 3. All Based On Universal ___________________________ (DNA) 4. __________________ & _____________________ 5. Obtain & Use Materials & ___________________ 6. ______________________ To Their Environment 7. _______________________ A Stable Internal Environment 8. AS A GROUP, Living Things _________________________, That Is They Change Over Time ALL ORGANISMS ARE MADE OF CELLS Cells are the smallest ______________ ____________ of an organism All cells contain living material called _____________________ All cells are surrounded by a cell ________________________ that controls what enters & leaves the cell Cells are complex & highly organized Cells have parts called ___________________ that do different jobs (Chloroplasts in plants make sugars) The simplest cells are called ________________________ These cells _________ have a nucleus or membrane-bound organelles Bacteria are examples More complex cells are called _____________________ These cells ________ have a nucleus and membrane-bound organelles Plants, animals, protists, & fungi are examples Organisms are Grouped by their Number of Cells _________________________ Organisms – Living Organism Made Up Of One Cell __________________________ Organisms – Living Organism Made Up Of Many, Specialized Cells ORGANISMS REPRODUCE TO PASS ON THEIR GENETIC TRAITS Two types of Reproduction ______________________ Reproduction Involves 2 parents Egg fertilized by sperm to make a ______________________ Offspring _______________________ from parents _______________________ Reproduction Involves a single organism or cell Cell __________________ Offspring ________________________ to parent CELLS HAVE A GENETIC CODE ______________ (deoxyribose nucleic acid) carries the genetic code for all organisms All organisms contain DNA DNA codes for the ___________ that make up cells & do all the work ORGANISMS GROW & DEVELOP Organisms _______________ by producing MORE _____________ & by cell __________________________ Organisms ________________ as they mature into an adult organism CELLS REQUIRE FOOD & ENERGY _________________ can make their own food _________________ use sunlight to make food (photosynthesis) _________________ use chemicals such as iron & sulfur as their energy _________________ can NOT make their own food They must consume other organisms _________________ eat plants _________________ eat meat _________________ eat plants & animals METABOLISM Sum of _____________ the chemical reactions in an organism All require _________________ _________________ is the ultimate energy for life on Earth ORGANISMS RESPOND TO STIMULI Organisms Respond to stimuli (Temperature, Water, Food Supplies, etc.) In Order To _________________ & _________________ HOMEOSTASIS Keeping The _________________ Environment (Homeostasis) Of The Cell or Organism Within The Ranges Required For Life Stable internal conditions of pH, temperature, water balance, etc. LIVING THINGS EVOLVE Groups Of Organisms (_______________________________) Change Over Time In Order To Survive Within Changing Environments. Fossil records show changes in groups of organisms
