Question

question 1 which of the following carbohydrates is used to store energy in plant cells? starch cellulose glycogen question 2 a team of researchers is investigating a new carbon - rich molecule important to life. they find evidence for the presence of a carbon - carbon double bond in the molecule. this observation means that the new molecule likely exists as which of the following? both cis and trans isomers an aliphatic hydrocarbon a hydrocarbon ring

Explanation:

• For Question 1: Starch is the carbohydrate used for energy - storage in plant cells. Cellulose is a structural component of plant cell walls, and glycogen is the energy - storage carbohydrate in animals.
• For Question 2: Carbon - carbon double bonds can give rise to cis - trans isomerism. Aliphatic hydrocarbons can have double bonds but the presence of a double bond doesn't necessarily mean it's just an aliphatic hydrocarbon. A hydrocarbon ring is not directly related to the presence of a double bond indicating cis - trans isomerism.

Answer:

Question 1: starch
Question 2: both cis and trans isomers
