Q1. Which of the following is/are found in plant cells but not in those of animals?
(a) Plastid & Cellular wall
(b) Chromosome
(c) Mitochondria & Golgi apparatus
(d) Cell wall & lysozyme
(UPSC Prelims 1987)
Answer: (a) Plastid & Cellular wall
Explanation: Plant cells possess plastids (like chloroplasts) and a cell wall, which are absent in animal cells. These structures are essential for photosynthesis and structural support in plants. Chromosomes, mitochondria, and Golgi apparatus are found in both cell types, and lysozyme is not a plant-specific feature.
