Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which organelle labels substances (proteins, etc) with messages (hormones) so that they can be used in the cell or outside of the cell?
A
ER
B
golgi bodies
C
ribosomes
D
lysosomes
Explanation: 

Detailed explanation-1: -This sorting, tagging, packaging, and distribution takes place in the Golgi apparatus (Golgi body), an organelle made up of flattened discs of membrane.

Detailed explanation-2: -The Golgi apparatus modifies, sorts, and packages different substances for secretion out of the cell, or for use within the cell. The Golgi apparatus is found close to the nucleus of the cell where it modifies proteins that have been delivered in transport vesicles from the Rough Endoplasmic Reticulum.

Detailed explanation-3: -Proteins are assembled at organelles called ribosomes. When proteins are destined to be part of the cell membrane or exported from the cell, the ribosomes assembling them attach to the endoplasmic reticulum, giving it a rough appearance.

Detailed explanation-4: -The Golgi apparatus, also called Golgi complex or Golgi body, is a membrane-bound organelle found in eukaryotic cells (cells with clearly defined nuclei) that is made up of a series of flattened stacked pouches called cisternae. It is located in the cytoplasm next to the endoplasmic reticulum and near the cell nucleus.

Detailed explanation-5: -Golgi apparatus is responsible for secretion of enzymes and hormones.
