Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which group of organelles is directly responsible for the production of new molecules within a cell?
A
Ribosomes, the endoplasmic reticulum, and Golgi apparatus
B
Golgi apparatus, lysosomes, and the plasma membrane
C
The endoplasmic reticulum, plastids, and vacuoles
D
The nucleolus, vacuoles, and ribosomes
Explanation: 

Detailed explanation-1: -So, the correct option is, ‘Ribosome, RER, SER’.

Detailed explanation-2: -Ribosomes. Ribosomes are the protein factories of the cell.

Detailed explanation-3: -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-4: -The ER membrane synthesizes nearly all of the major classes of lipids, including both phospholipids and cholesterol, required for the production of new cell membranes.

Detailed explanation-5: -The nucleolus is a dense, round, dark staining, granular organelle without a limiting membrane. It forms ribosomal subunits by wrapping the rRNAs with ribosomal proteins.
