Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Acts like a subway system, carrying protein through the cell.
A
Golgi Apparatus
B
Nuclear Membrane
C
Ribosomes
D
Endoplasmic Reticulum
Explanation: 

Detailed explanation-1: -The Golgi processes proteins made by the endoplasmic reticulum (ER) before sending them out to the cell. Proteins enter the Golgi on the side facing the ER (cis side), and exit on the opposite side of the stack, facing the plasma membrane of the cell (trans side).

Detailed explanation-2: -From the endoplasmic reticulum, proteins are transported in vesicles to the Golgi apparatus, where they are further processed and sorted for transport to lysosomes, the plasma membrane, or secretion from 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 “subway system” of the cell. Found in the plant cell, these organelles capture energy from sunlight and use it to produce food for the cell. A storage sac for water, food, waste products, and other materials. Mature plant cells usually have one, animal cells have more than one.
