Characteristics of LivingThingsLife Science

Objectives Be able to determine whether something is aliving thingora non-living thing. Learn and understand the 5 maincharacteristics of living things. (ROGER)

Organism A living thing

How do you know whensomething is living?

RespondLiving things respondto their environment.

Why is Buddy screaming?

Buddy is responding to the facechewing the bone!

Stimulus: anything that causes achange in an organism. Causes the organism to react

Response: a reaction orchange in behavior dueto the stimulus.

A stimulus causes a ResponseWhat is the stimulus here?Music stimulusDancing response

Homeostasis: Living things maintain astable internal balanceThe ability to keep the proper conditionsinside no matter what is going on outside.

Organized Living things are all composedof cells. Cells: The basic unit of life thatcarries on the life functions.

Organisms can be1-celleduni-cellular bacteriaAmoeba

Are you Uni-celled or Multicelled? Multi –celled!You are made up of manylittle cells that are differenttypes with different jobs*multi-celled- madeup of different kinds ofcells with different jobs(specialized cells)

Multicellular organisms.Plants & animalsMany celled multi-celled *multi-celledmadeup of differentkinds ofcells with differentjobs(specialized cells)

Living things are organizedAll of the little cells that come together tomake up living things do so in a specificorder. For example a group of muscle cells cometogether to form our muscles.

Here are some types of cells in yourbody .Can you guess what type of cells theyare?White blood cellsRed blood cellsCardiac muscle cell

Grow and Develop Growth: Unicellular organismincrease in cell size.Multicellular organism increase thenumber of cells.

Grow Growth- get larger in size

Development:Organisms grow andbecome morecomplex, they changephysically and in theirabilitiesMetamorphosis Ex: walking body changes over time

ROGER

Energy Energy comes directly or indirectly fromSun.Heterotrophs: Animals and humanseat food to obtain their energy.Consumer (heterotroph)Eats other organisms for food,does not make own food

Autotrophs: Plants however use thesunlight to obtain their energy. Make theirown food.Producer (autotroph)Makes own food usingsun’s energy.

The squirrel's cells are able to workbecause of the energy he obtained by eatingberries, produced by a plant, using theenergy from the sun.

ROGER

Living Things Reproduce Living things produce offspring that aresimilar to parents:HYDRA

ReproductionAsexual Reproduction: One cell(1 parent) divides in half making anexact copy.The offspring are identical tothe parent!

ReproductionSexual Reproduction: cells from 2parents:egg and sperm.Offspring are NOT identical to theparents!

What do living things need? To survive, all living things need aplace to live and raw materials. The raw materials that they requireand the exact place where they live canvary.

Place to livethe environment limits whereorganisms can live. An organism’s surroundings mustprovide for all its needs

Raw materialsAll living things need water. Most organisms are composed ofmore than 50 % water

Raw materials .Living things are made up ofsubstances such as proteins, fats,and sugars.

Animals take in most of thesesubstances from their food.

Plants and some bacteria makethem (proteins, fats and sugars)using raw materials from theirenvironment (surroundings).

Grow and Develop Growth: Unicellular organism . Grow Growth- get larger in size. Development: Organisms grow and become more complex, they change physically and in their . To survive, all livin
