Answer:
The correct answer is Endoplasmic reticulam.
Step-by-step explanation:
Endoplasmic reticulam or ER is in important organelle present in the cytoplasm.Endoplasmic reticulam are of 2 types
1 Rough endoplasmic reticulam
2 smooth endoplasmic reticulam
Rough endoplasmic reticulam contain ribosomes in its outer surface and play an important role in the biosynthesis of protein molecules with the assembly of ribosomes that it contains .
Smooth Endoplasmic reticulam helps in the biosynthesis of phospholipid.
The so formed protein molecules and phospholipid helps in the formation of cell membrane.
