Considering That Leaf Stoma Have the Conflicting Functions of Allowing

question 30

Multiple Choice

Considering that leaf stoma have the conflicting functions of allowing gaseous carbon dioxide into the leaf, yet preserving the plant's supply of water, which of the following is (are) reasonable?

• A) A submerged-water plant would have no stoma.
• B) Tree leaves that orient flat and present the top side to the sun would have most of their stoma on the bottom of the leaf.
• C) Corn, oats, rice, and wheat-all monocots-have relative upright blades with sunlight hitting both sides and would have stoma distributed evenly on both sides.
• D) All of the choices are reasonable.
• E) None of the choices is reasonable, since stoma are found uniformly on all type of leaves.

Definitions:

Gene Expression

The process by which the information encoded in a gene is used to direct the assembly of a protein molecule.

Target mRNA

Messenger RNA molecules identified for binding by specific proteins or molecules, typically for the purpose of regulating gene expression.

Translation

Translation is a process in molecular biology through which messenger RNA (mRNA) is decoded by a ribosome to produce a specific amino acid chain, or polypeptide, that will then fold into an active protein.

Proteolytic Processing

This refers to the enzymatic breakdown of proteins into smaller polypeptides or amino acids.
