All living things share some basic properties
Cells Organization Energy Use Homeostasis Growth and Development Reproduction

Cells
Basic unit of life Carry out the functions of life All organisms have 1 or more cells.
Human skin Plant leaf Bacteria

Cells Unicellular organisms
Made of 1 cell Each cell has everything necessary for
life Include bacteria and protists

Cells
Multicellular Organisms Made up of many cells Cells have specialized functions within
the organism

Organization
Living things are much more complex than anything non-living. More complex molecules, structures organized
into groups.
Non-living: composed of atoms and/or molecules
Living: macromolecules, organelles, cells
Protein
Cell with many organelles

Other levels of Organization
TISSUE ORGAN ORGAN-SYSTEM

Energy Use
Living things need energy to grow, develop, repair damage, and reproduce
Known as metabolism

Autotrophs vs. Heterotrophs
Autotrophs, like plants, can make their own food using the sun’s energy and Earth’s inorganic molecules.
Heterotrophs, like the bird that eats fish, consume other organisms.

Homeostasis Maintain stable internal conditions.
Response to the environment. Includes body temperature, blood volume,
removal of waste, pH balance, and water balance

Growth and Development
Growth Cells divide to
make more cells and the organism gets bigger

Growth and Development
Development Cells take on specific roles (differentiation). Physiological change or change in form may
occur.

Reproduction
Pass genetic information (DNA) along to produce more members of a species.

Reproduction
Asexual reproduction A single organism reproduces by
itself

Reproduction
Sexual Reproduction 2 different parent organisms contribute
genetic information to an offspring

From what you learned about the characteristics of life:
Look at the 2 items at the front of the room. What observations can you make about each item. They will be passed around for you to make these observations.
With your partner decide if they have been alive, if they are currently alive, and how we would know based on the characteristics of life.
Could we set up an experiment with each to find out?
