1) ALL LIVING THINGS HAVE CELLS. THE CELL IS THE BASIC UNIT OF LIFE.
All organisms are made up of at least 1 cell
Usually microscopic in size, trillions of microscopic cells in trees or in us!
2) ALL LIVING THINGS NEED ENERGY!
Energy is the ability to make things move or change
Organisms get energy from the environment:
Plants = Sun
Animals = Surrounding environment
NUTRIENTS: Substances that provide the energy (fat, protein, carbohydrates) and materials (minerals, vitamins) that organisms need to grow, develop, and reproduce! METABOLISM: The sum of all the different processes that happen inside an organism
Energy is converted inside the cell for us to use, the energy amount has to be balanced:
Too much energy conversion = obesity
Too little energy conversion = malnutrition
3) ALL LIVING THINGS RESPOND TO THE ENVIRONMENT!STIMULUS: Anything that causes a response in an organism RESPONSE: An organism’s reaction to a stimulus 4) GROW AND DEVELOP
Bigger and change of structure
Changing of body shape
5) REPRODUCE
All living things come from other living things
Reproduction does not mean an individual organism will survive, but the survival of the species
6) ADAPT TO THEIR ENVIRONMENT ADAPTATION: Physical or behavioural characteristic of a species that increases the species’ chances of survival in a particular environment Draw a hierarchy for the six characteristics of living things
Structure and Function
ALL LIVING THINGS NEED TO DO CERTAIN THINGS TO STAY ALIVE!
Ex. Hunt for food, exchange gases & nutrients
As such, organisms have developed different ways of doing these tasks
STRUCTURE: Parts of an organism that perform specific tasks to survive FUNCTION: Purpose or task
Different Structures for Similar Functions
But different plants and animals have developed different structures for doing similar functions
Example: Using light to respond to the environment
