Cell Organelles

Question 1

Ribosomes

RYE-boh-sohms

Answer 1

Tiny particles; made up of rRNA units

Function: Protein Factories

Question 2

Endoplasmic Reticulum (ER)
(en-doh-PLAZ-mik reh-TIK-yoo-lum)

Answer 2

Membranous network of interconnected canals and sacs; rough ER: with ribosomes attached; smooth ER: without attachment
Function:
Rough ER > receive and transport new proteins
Smooth ER > makes new membrane
