Indicate whether each of the following descriptions better matches the rough (R) or the smooth (S) endoplasmic reticulum.

a. it mostly has a tubular appearance.
b. It is coated by ribosomes.
c. It can be specialized for functions such as detoxification and lipid metabolism.
d. sarcoplasmic reticulum in muscle cells is one of its specialized forms

rough endoplasmic reticulum--b

Smooth endoplasmic reticulum--a,c,d

Explanation:The rough endoplasmic reticulum has numerous ribosomes attached to it. Thus it has a coarse texture.it is involved in the production of proteins. The ribosomes receives the messages to produce a protein from the messenger RNA, the ribosome the packs amino acid into proteins and transfers it to the rough endoplasmic reticulum.

The smooth endoplasmic reticulum does not have ribosomes attached.it is involved in the production of non-protein molecules eg lipids and fats.

It is an also important organelle for the metabolism of the cell.it helps in detoxification in the liver. It also stores calcium for use in the skeleton.The sarcoplasmic reticulum is an modified smooth endoplasmic reticulum

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
