The green pigment that traps light energy in plants is located in the: MCQ with Answer and Explanation

Explanation:
Sewage contains organic matter that can be broken down by microorganisms, hence biodegradable. DDT, plastics, and mercury are non-biodegradable, persisting in the environment and accumulating in food chains (biomagnification). Biodegradable pollutants can be decomposed naturally, reducing long-term harm, but excessive loads can cause eutrophication. Non-biodegradable pollutants require special disposal and cause lasting ecological damage.

Explanation:
Metabolism is the sum of all chemical reactions occurring in a living body. It is the only feature present in all living organisms without exception. While growth and reproduction are common, they are not universal (e.g., sterile mules). Non-living things can also exhibit growth by accumulation or movement, making metabolism the true defining property.

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.
