Different Types of ER

APBIO-QEIEXH

The structure of an organelle determines its function. All organelles have very specific functions and thus have very specific structures. Two examples of organelles with specified structural characteristics are the smooth and rough endoplasmic reticulum.

Identify the correct description of the structures of the smooth and rough endoplasmic reticulum.

N.d. Https://simple.wikipedia.org/wiki/Endoplasmic_reticulum. Web. 30 Jan. 2016.

A

The rough endoplasmic reticulum is a network of sac-like structures that are held together by the cytoskeleton and have ribosomes attached. The smooth endoplasmic reticulum is a tubular network.

B

The smooth endoplasmic reticulum is a network of sac-like structures that are held together by the cytoskeleton and have ribosomes attached. The rough endoplasmic reticulum is a tubular network.

C

The rough endoplasmic reticulum is a network of sac-like structures that are held together by the cytoskeleton The smooth endoplasmic reticulum is a tubular network that has ribosomes attached.

D

The rough and smooth endoplasmic reticulum are both tube like structures held together by the cytoskeleton and contain bound ribosomes.
