For the job of creating proteins, which organelle does NOT belong?
A
cell membrane
B
nucleus and nucleolus
C
ER
D
ribosomes
Explanation: 

Detailed explanation-1: -Nucleolus. Within the nucleus is a small subspace known as the nucleolus. It is not bound by a membrane, so it is not an organelle. This space forms near the part of DNA with instructions for making ribosomes, the molecules responsible for making proteins.

Detailed explanation-2: -Non-membrane-bound cell organelles include the cell wall, ribosomes, and cytoskeleton.

Detailed explanation-3: -The organelles involved in the process of protein synthesis include the nucleus, ribosomes, endoplasmic reticulum (ER) and the golgi apparatus (GA).

Detailed explanation-4: -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-5: -In both eukaryotes and prokaryotes, ribosomes are the non-membrane bound organelles where proteins are made. Ribosomes are like the machines in the factory that produce the factory’s main product.
