The process by which plants produce glucose using light energy is called: MCQ with Answer and Explanation

The process by which plants produce glucose using light energy is called:
A. Respiration
B. Fermentation
C. Chemosynthesis
D. Photosynthesis
Answer: Option D
Solution (By JKExamLibrary)
Photosynthesis is the anabolic process in which plants, algae, and cyanobacteria convert CO₂ and H₂O into glucose and O₂ using light energy, catalyzed by chlorophyll. Respiration breaks down glucose to release energy, fermentation is anaerobic breakdown, chemosynthesis uses chemical energy (in some bacteria).

The type of asexual reproduction in yeast where a small outgrowth develops into a new individual is:
A. Spore formation
B. Budding
C. Fragmentation
D. Binary fission

Correct Answer: Option B


Explanation:
Budding is an asymmetric division where a new yeast cell forms as a small bud on the parent, eventually pinching off. Binary fission is symmetric splitting (bacteria), fragmentation is breaking into pieces, spore formation involves spores. Budding can occur in some hydra as well.
