[a] In the given diagram of endoplasmic reticulum, the components marked as 1, 2, 3, 4 and 5 are respectively nucleus (viii), rough endoplasmic reticulum (v), ribosomes (vii), cytoplasm (iii) and smooth endoplasmic reticulum (iv).
Endoplasmic reticulum is a network of membranous tubules within the cytoplasm of a eukaryotic cell, continuous with the nuclear membrane.
It usually has ribosomes attached and is involved in protein and lipid synthesis
