A cell is the basic unit of living organisms (both plants and animals)
that is capable of reproducing itself exactly. That is, there are
components within cells (organelles), but they do not reproduce themselves
independently of the cell(s) of which they are a part.
Ribosomes are particles consisting of ribonucleic acid (RNA) and protein
that interpret cellular information from the nucleus and synthesize
appropriate proteins
as required by the cell.
Ribosomes are either attached to the endoplasmic reticulum (RER) or
free in the cytoplasm as polysomes. See the Revision page about Cell
Structure for further information including a diagram of the
structure of a basic cell including ribosomes and other organelles. |
