all living things are composed of cells
cells are a baisc unit of structure and function in living things all cells are produced from other cells. |
|
|
endoplasmic reticulum(E.R.)

ribosomes
|
attached to the E.R are small grainlike bodies
|
|
|
cell membrane
|
all cells have membranes- it forms a cell barrier- also protects the cell
|
|
|
micro info
