Answer 2

ENDOPLASMIC RETICULUM
ITS a large netwrk of membrane bound tube and sheets extending from outer nucleur membrane towars plasma  membrane...
Based on presnce of ribosomes E.R is of two types:
ROUGH ENDOPLASMIC RETICULUM. ...SMOOTH ENDOPLASMIC  RETICULUM. ..
RER.contains ribosomes and helps in protein synthesis..
SER which doesn't  contain ribosomes and helps in lipid synthesis and fat synthesis...it also helps in detoxification of poison and drugs...Its acts as intercellullar transportation channel carrying cell materials from one place to another...
