• Life Processes(Activities) These are the
  processes that all livings things must accomplish
  in order to be alive. Think of some of the
  things you need to survive

These are the official life processes

• Transport Regulation
• Respiration Growth
• Excretion Reproduction
• Synthesis Nutrition

Transport

• Multicellular organisms must transport
  nutrients to all cells and remove wastes from
  those cells. Humans use our blood stream, or
  circulatory system, while single cells use an
  intracellular network in the cytoplasm made of
  microtubules.

Respiration

• The release of energy from food. The
  MITOCHONDRIA is where this happens.  Most life
  forms receive energy from glucose. Some can form
  ATP from glucose using Oxygen and others form ATP
  from glucose without using oxygen. Dou you know
  the difference between aerobic respiration and
  anaerobic respiration?

C6H12O6 6O2 ? 6CO2 6H2O 36 ATP

Excretion

• Getting rid of wastes. You know how we get rid
  of wastes. Single-celled organisms and single
  cells use exocytosis and membrane transport. 

exocytosis
8
Synthesis

• Building bigger things from smaller things for
  growing or maintenance. Humans synthesize new
  cells all the time, like our skin cells. We also
  make new cells as we grow. Single-celled
  organisms and single cells make new proteins in
  the ribosomes. 

9
Regulation

• A response to maintain stability, or homeostasis.
  We drink water when it is hot out to replace
  water we are loosing. Single cells respond to
  heat by also absorbing more water. There are
  many examples of regulation. Can you think of
  one?

Which of these illustrates dynamic equilibrium?
11
 Growth

• The increase in size of an organism. This is
  made possible by synthesis. We grow by making
  new cells while protozoa and other single-celled
  organisms grow by just getting bigger.  

12
After dividing, these cells will grow to become
as large as the cells on the right.
13
Reproduction

• Producing more of the same kind. All living
  things have the drive to reproduce. From
  bacteria to humans, reproduction is built into
  our genetics. This is the only life process that
  individuals do not need to survive.

14
Nutrition is the obtaining and processing of
food. We and other organisms obtain food by
eating. This is called heterotrophic nutrition.
Plants make their food during photosynthesis in
the chloroplasts. This is called autotrophic
nutrition.

Is a mushroom heterotrophic or autotrophic?
Heterotrophic, mushrooms feed off of dead plant
matter. They do not make their own food
