made up of cells
|
-some living things are unicellular
-some living things are mulitcelluear |
|
|
unicellular
|
-made up of one single cell
|
|
|
multicellular
|
-made up on two or more cells that work together to live
|
|
|
reproduction
|
-can take place at the cellular level or the organism level
|
|
|
cellular level
|
-individual cells reproduce to make new cells, called daughter cells
|
|
|
organism level
|
-individual organisms reproduce to make new organisms, called offspring
|
|
|
homeostasts
|
-maintaining a constant state
-must adapt to their external environment -must adapt to their internal environment |
|
|
external environment
|
changes in temp, light, or moisture
|
|
|
internal environment
|
changes in temp on the inside, nutrient levels, hormones
|
|
|
responsiveness
|
-must be able to react to their internal and external conditions
|
|
|
metabolism
|
-obtain and use energy
-put together molecules -take apart molcules |
|
|
putting together molecules
|
two or more smaller molecules become on larger molecule
|

heredity
|
all living organisms contain DNA
|
|
|
DNA
|
-they are able to pass traits or characteristics form parent to offspring
|
|
|
asexual reproduction
|
-clones
-some offspring are identical to the parents |
|
|
sexual reproduction
|
some offspring are a genetic combination of the parents

|
|
growth and development
|
-after reproducing, all cells grow
-as cells grow, they change, or develop. Cells need to develop so that they can take on new functions necessary to maintain life. |
|
|
how do unicellular organisms grow
|
grow in size because the cell grows
|
|
|
how do multicellular organisms grow
|
grow in size because the number and the size of the cells increases
