  1. Endoplasmic Reticulum (ER) By: John Dryden and Zach Tan

  2. Structure The Endoplasmic Reticulum, also known as ER, is a membrane system made up of folded sacs and interconnected channels. ER is able to allow a lot of room in its surface area. Some sides are rough and some are smooth on the ER. The rough sides have ribosomes attached to their sides making them rough. This allows for it to be a main and vital part of the cell.

  3. Location The ER is located inside the cell specifically around the nucleus. The rough side of the ER is closer to the nucleus while the smooth side is farther away.

  4. Functions The main function of the ER is to produce protein and lipids. It will then transport the protein to other parts of the cell along with carbohydrates. It is like a conveyer belt because after things are made they are sent down the belt to other parts of the factory. When an object is created in a factory, it is then sent down the belt to be used in other ways somewhere else. The other functions of the ER include the sides of the ER. The smooth side of the ER acts as an antidote to harmful substances. The rough side of the ER makes proteins that will be transported.

  5. The ER is only in eukaryotic cells such as plant and animal cells. This is because eukaryotic cells have a nucleus and prokaryotic cells do not. Only in (?) cells
