Characteristics of-life1805
All living things share some basic properties.
Cellular Organization
Reproduction
Metabolism (Obtain and Use Energy)
Homeostasis
Heredity
Responsiveness
Growth and Development
Adapt Through Evolution
Smallest unit capable of all life functions
Unicellular Organisms
    Entire organism is made up of one single cell
    Bacteria and protists
Multicellular Organisms
The organism is made up of many
cells
Cells have specialized functions
within the organism
Reproduction is the process of producing new
organisms of the same type

Asexual Reproduction
   A single parent organism reproducing by itself
Sexual Reproduction
Two different parent organisms contribute genetic
information
Involves the combination of male and female sex
cells
Living organisms need energy to
grow, develop, repair damage, and
reproduce
Anabolism
The process of building up complex substances
from simpler substances
  Building up cells and cellular components
  Photosynthesis
Catabolism
The process of breaking down complex
substances into simpler substances to release
energy
 Digestion

 Cellular Respiration
Metabolism
The total of all chemical reactions in
an organism
 Anabolism + Catabolism = Metabolism
A stable state of conditions in the body
that are necessary for life


Body temperature
Blood volume
pH balance
Water balance
Genes carry hereditary information
Genes are composed of DNA
Heredity is the reason children resemble their parents

                                 Mutations change
                                 DNA code and can be
                                 passed from
                                 generation to
                                 generation
An example is a plants
Organisms react to stimuli:   leaves and stems growing
Light                        toward light

Temperature
Odor
Sound
Gravity
Heat
Water
Pressure
Growth means to get bigger in size
Development involves a change in the
physical form or physiological make-up of
an organism
Adaptation
A process that enables
organisms to become better
suited to their environment
 Species obtain adaptations
through evolution over great
periods of time
An Example of Adaptation




Desert plants have succulent waxy leaves and
stems to store water and reduce water loss
