Question 2

Scenario
A renewable alternative to fossil fuels are biofuels. Scientists are searching for the best plants to use as a source of biofuels. Plant sugars can be fermented into ethanol, and then used as an additive to gasoline. Although it is relatively easy to obtain ethanol in this way, this type of ethanol production competes with the need to produce food. Alternatively, biofuels can be fermented from other plant carbohydrates, such as the cellulose in plant cell walls. This is called cellulosic ethanol production. 
-Energy input is required to process plant matter in a way that prepares plant cells for cellulosic ethanol production. Lignin needs to be removed to make cellulose accessible. Why is there a greater efficiency in obtaining biofuels from grassy monocots rather than woody eudicots?

Accepted Answer

A) Lignin is the main chemical component of wood. 
B) Grassy monocots grow with both primary and secondary growth, while woody eudicots only have primary growth. 
C) The cell walls of woody eudicots do not contain cellulose. 
D) Only grassy monocot cells have central vacuoles, which can store cellulase. 
A) Lignin is the main chemical component of wood. 
B) Grassy monocots grow with both primary and secondary growth, while woody eudicots only have primary growth. 
C) The cell walls of woody eudicots do not contain cellulose. 
D) Only grassy monocot cells have central vacuoles, which can store cellulase.

Question 3

Bermudagrass is a plant that is commonly used on golf courses. It has a fibrous root system, and its leaf veins are parallel.

Accepted Answer

A) It is a perennial monocot that reproduces asexually. 
B) It is an annual eudicot that reproduces asexually.
