smallest unit capable of life functions.
2. Which biomolecule is primarily responsible for storing
genetic information?
A. Lipids
B. Proteins
C. Carbohydrates
D. Nucleic acids

Rationale: DNA and RNA store and transmit genetic
information.
,3. What is the main function of mitochondria?
A. Protein synthesis
B. Energy production
C. Lipid storage
D. Waste removal
Correct answer: B. Energy production
Rationale: Mitochondria produce ATP through cellular
respiration.
4. Which process allows plants to make glucose using
sunlight?
A. Respiration
B. Fermentation
C. Photosynthesis
D. Transpiration
Correct answer: C. Photosynthesis
Rationale: Photosynthesis converts light energy into chemical
energy (glucose).
