Consider statements about plant biology: 1. Photosynthesis occurs in chloroplasts. 2. Respiration occurs in mitochondria. 3. Transpiration occurs through lenticels. Which are correct? MCQ with Answer and Explanation

Photosynthesis, the process of converting light energy into chemical energy, occurs in the chloroplasts, specifically involving the thylakoid membranes and stroma. Cellular respiration, the process of breaking down glucose to release ATP, occurs primarily in the mitochondria. Transpiration is the loss of water vapor from plants, and while it can occur through lenticels (lenticular transpiration) and the cuticle, the vast majority (about 90%) occurs through the stomata (stomatal transpiration). Thus, statements 1 and 2 are correct.
