Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which organelle prepares proteins and sends them to the Golgi after they are made; this organelle is covered in ribosomes?
A
Smooth Endoplasmic Reticulum
B
Rough Endoplasmic Reticulum
C
Golgi Body
D
Mitochondria
Explanation: 

Detailed explanation-1: -The endoplasmic reticulum (ER) is involved in the synthesis of lipids and synthesis and transport of proteins.

Detailed explanation-2: -Protein cargo moves from the ER to the Golgi, is modified within the Golgi, and is then sent to various destinations in the cell, including the lysosomes and the cell surface. The Golgi processes proteins made by the endoplasmic reticulum (ER) before sending them out to the cell.

Detailed explanation-3: -Proteins Leave the ER in COPII-coated Transport Vesicles To initiate their journey along the biosynthetic-secretory pathway, proteins that have entered the ER and are destined for the Golgi apparatus or beyond are first packaged into small COPII-coated transport vesicles.

Detailed explanation-4: -Definition. A Golgi body, also known as a Golgi apparatus, is a cell organelle that helps process and package proteins and lipid molecules, especially proteins destined to be exported from the cell.

Detailed explanation-5: -Plant cells can contain as many as several hundred smaller versions. The Golgi apparatus receives proteins and lipids (fats) from the rough endoplasmic reticulum. It modifies some of them and sorts, concentrates and packs them into sealed droplets called vesicles.
