My name is Endoplasmic Reticulum, and I look like a canal. There are two different types of me, the rough ER, and the smooth ER. The ER is attached to the nuclear membrane. The rough ER has ribosomes covering the outside layer. The smooth ER has no ribosomes covering the outside layer. The ER is located next to the cytoplasm (the material making up the cell other than the nucleus or nucleoid.)

The ER's characteristics

I am important to the cell because I account for half of the membranes in the cell. Another reason I am important to the cell is because I supply a maze of channels for carrying protein and other substances around the cell. And my last reason for being important to the cell is because the amount of the rough ER in the cell determines how much protein the cell makes. I work with the Golgi apparatus by taking a vesicle of cistern and transporting it to the Golgi apparatus. I am a complicated double-unit membrane matrix of channels, flattened sacs, and tubules in eukaryote cells ( an organism who has cells that have a defined nucleus.) that are non-stop with the nuclear membrane. I am found in both animal cells and plant cells.
