Lifeboat Dilemma

Imagine yourself in a ship which just struck an iceberg and the captain is lead to choose who will be thrown out. Now every passenger needs to convince the captain the reasons they shouldn´t be thrown out. This is basically the task given by my teacher but instead of being humans, each student was given an assigned cell part. The class was divided in two main cells, prokaryotic and eukaryotic. This represents the ships.  The passengers are the different cell parts present in either a prokaryotic or eukaryotic cell. 
My assigned part was the endoplasmic reticulum. The speech I presented was the following: 

The endoplasmic reticulum is a network of membranes, classified in two types: rough and smooth. The main functions of the rough endoplasmic reticulum are synthesis and storage of proteins which are made by the ribosome’s attached to it. The smooth endoplasmic reticulum plays a role in the lipid synthesis and, in muscle cells, in the conduction of the contraction stimulus.

Proteins are needed in the cell for numerous functions and the RER (rough endoplasmic reticulum) is responsible for synthesizing proteins. They can either produce a protein to reproduce or to replace a degraded one. Their procedure is to first transcribe DNA into RNA. The RNA will translate into chains of amino acids, then, the amino acid chain will fold into specific proteins.

The same as the nucleus acts as the brain of the cell, the endoplasmic reticulum acts as the transport system by sending protein to the golgi apparatus.
