Brainlies asap! : ) describe the structure and function of the endoplasmic reticulum (both rough er and smooth er). v

Smooth ER

- Smooth ER is an arrangement of tubules, vesicles and sacs.

- The size and structure of the SER varies between the cells.

- The SER can change within a cells lifetime to allow the cell to adapt to changes in its function and requirements.

- There are no riobsome's attached to the membrane surface.

- The SER is connected to the nuclear envelope

Rough ER

- Rough appearance because it has ribosomes

-Function: Site of protein synthesis - thus is why it has ribosomes

- Lined with ribosomes

- Modifies proteins that are being transported

- Made of RNA and protein

- Assemble proteins based on instructions from DNA

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.
