do you kno any everday object like a nuclear membrane?or endoplasmic reticulum?

Answer 1

It depends on how you are asking. If you are asking about function, then yes.

The nuclear membrane encloses the nucleus of a cell. Through this membrane passes the RNA to meet up with the ribosomes that are located on the endoplasmic reticulum. The ER will take this RNA, using its code (instructions) to make proteins, which it will then ship to the golgi apparatus to be refined.

The endoplasmic reticulum is made up of two parts: the rough ER and the smooth ER. The difference is that the rough ER is studded with ribosomes; the smooth ER is not. When RNA meets with the ER, it will go to the rough ER because it is the ribosomes of the rough ER that are doing the work. The product the rough ER makes will then go to the smooth ER, which will then send it to the golgi apparatus.

Think of an everyday thing like a restaurant:

1. I hand in my food order
2. They look at that order and get the food
3. With that food they cook my order
4. They deliver the final product to me so that I can eat it

1= nuclear membrane; 2&3= endoplasmic reticulum; 4=golgi
Without my order (the information from the nuclear membrane), the restaurant would not know what food to use and what to cook(ER), so in the end nothing can be delivered (golgi).

Hope this helps!
