This organelle is mostly found on the ER but can be found in other areas within the cytoplasm. Where protein synthesis occurs.
A
Endoplasmic Reticulum
B
Chloroplast
C
Ribosomes
D
Nucleus
Explanation: 

Detailed explanation-1: -Membrane-bound ribosomes, attached to the cytosolic side of the ER membrane, are engaged in the synthesis of proteins that are being concurrently translocated into the ER.

Detailed explanation-2: -The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function. The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins.

Detailed explanation-3: -Endoplasmic reticulum is an organelle found in both eukaryotic animal and plant cells. It often appears as two interconnected sub-compartments, namely rough ER and smooth ER. Both types consist of membrane enclosed, interconnected flattened tubes.

Detailed explanation-4: -Explanation: Ribosomes are composed of a unique type of RNA, rRNA, and are located within the cytoplasm of the cell and on the surface of the rough endoplasmic reticulum.

Detailed explanation-5: -ER and Golgi The Golgi forms membrane contacts with the ER to regulate the transfer of secreted proteins and lipids (Glick and Nakano 2009).
