the process by which living things produce new living things of the same kind
there are 2 types
1) asexual reproduction--involves one parent and the offspring are identical to the parent
2) sexual reproduction--involves two parents and the offspring is a combination of both parents

the process by which living things remove waste products produced by cell activities

the process by which living things increase in size or cell number

the process by which living things take in materials from its environment for growth and repair; there are 2 types
1) autotrophic nutrition--where a living thing can make its own food
2) heterotrophic nutrition--where a living thing must ingest (take in) its food

the process by which usable materials are taken into the living thing (ABSORPTION) and distributed throughout the living thing (CIRCULATION)

the process by which smaller, simple substances are combined chemically to form larger, more complex substances

If a living thing has all 8 off these life functions, it is called an ORGANISM!

When we refer to all of the life functions of an organism, we are referring to its METABOLISM--the total of all the life functions required to sustain life (to stay alive)

R + R + R + E + G + N + T + S =

An organism's external (outside) environment is always changing. By keeping the control and regulation of its metabolic activities, an organism can maintain a stable internal (inside) environment. This is called HOMEOSTASIS.

the process by which an organism's metabolic activities are in a state of balance
ex. body temp, blood sugar levels
