Ribosomes manufacture proteins!
Ribosome
The ribosomes are attached to the endoplasmic reticulum.
Purpose
The ribosomes translate RNA into proteins.
Function
The ribosomes are small organelles attached to the endoplasmic reticulum. They take the RNA, which is a series of instructions from the nucleus, and translates into proteins, which are instructions that the cell can understand. They are very small, only about 10 nano-meters (smaller than most viruses).
Location
The ribosomes are attached to the endoplasmic reticulum.
Number
There may be hundreds in each cell
