    As humans, we need to understand our relationship to and how we impact other living organisms in our environment.




Characteristics of life

Characteristics of Life

What characteristics must something have in order to be considered living?


1 reproduction all living things reproduce
1. Reproduction – all living things reproduce




  • Species—a group of similar looking organisms that can interbreed and produce fertile offspring.


2. Adaptation – when an organism changes & the change allows for better survival, the organism has adapted.



3 response stimulus and response
3. Response (Stimulus and Response)

  • *Stimulus – the thing that causes a change in an environment

  • *Response – reaction to the change/stimulus

  • Ex. Stimulus – It’s raining outside

    Response – You ???


4 energy
4. Energy

all living organisms use energy (ATP)

Ex. Metabolism:sum of chemical energy that an organism uses

Energy is the ability to do work

Work is force times distance (W=fxd)


5. Homeostasis organisms strive to reach equilibrium or balance

Ex. Body temperature, blood sugar, pH concentration, etc.


6 organization
6.Organization

all living things are organized

  • Show an orderly structure

  • Are unicellular (one-celled) or

  • multicellular (many-celled)

  • cells->tissue->organ->organ system

    ->Organism


7 growth development
7.Growth & Development


  • Growth – an increase in the amount of living material & formation of new structures


  • Development – bodily changes an organism undergoes.

    Ex. Puberty
