Review previous day Biotic/Abiotic hike

• What were the questions we left with yesterday?

Organisms

• An ORGANISM is a living thing• All organisms share characteristics

that separate them from non-living things

• All organisms share SIX characteristics that make them alive. A living (biotic) organism must have all six !

All living things… are made up of cells.

• A cell is the smallest “unit of life”

• CELL: the smallest basic unit of structure and organization of all living organisms

• Some organisms have only a single cell… others have many – the human body contains over 100 trillion cells

That’s 100,000,000,000,000!!

All living things…display organization.

• Arranged in an orderly way• Cells Tissues Organs

Organ Systems Organism

All living things…grow and develop

• Growth: addition of mass to an organism

• Development:the process that occurs in an organism's life that results in a more complex organism.

Basically, this means that they can make more of their own kind!

• SPECIES: A group of organisms that mate together and have fertile offspring

• Asexual Reproduction – when a single parent doubles its contents and splits in two to create a new organism (ex:bacteria)

• Sexual Reproduction – when two different parents unite to produce a new organism (ex:humans)

MITOSIS

All living things…reproduce.

All living things…respond to stimuli.

• Stimuli: Anything from the environment that causes some sort of reaction, such as temperature, light, sound, and other factors that cause living things to respond. Nonliving objects (rocks for instance) do not respond to stimuli!

All living things…require and use

energy.Used to run the processes of life• Humans (and other animals) get

energy from the food we eat• Plants get energy from the

sunlight, through a process called photosynthesis

Quick Group Discussion!!!

• What about dead things?

6 Characteristics of Living Things

How can we remember these?!
