The statement that accurately describes biomolecules is:
"they include carbohydrates, lipids, proteins, and nucleic acids."
The other statements are incorrect:
- Biomolecules are not only found in plants; they are present in all living organisms, including animals and microorganisms.
- They are important for various functions, not just energy storage. For example, proteins play roles in catalyzing reactions and providing structure.
- Biomolecules are generally larger macromolecules that play critical roles in cellular function, not small molecules that do not contribute to these functions.
