Which of the following is a correct statement about a typical bacterium? MCQ with Answer and Explanation

Explanation:
Photosynthesis, the process of converting light energy into chemical energy (glucose), occurs in the chloroplasts of plant cells, specifically involving the thylakoid membranes and stroma. Cellular respiration, the process of breaking down glucose to release ATP for cellular work, occurs primarily in the mitochondria of both plant and animal cells. Transpiration is the loss of water vapor from the aerial parts of the plant, primarily through the stomata on the leaves, not through the roots (which absorb water). Thus, statements 1 and 2 are correct.

Explanation:
The living state and all vital functions first become evident at the cellular level. While macromolecules are present in both living and non-living systems, it is the organized interaction of these molecules within a cell that manifests life. Cells are the fundamental structural and functional units of life.
