Solution :(c) GYMNOSPERMS, (e.g. PINUS) are commonly called as naked seeded plants since their ovules (which later BECOME seed) are not covered and LIE naked on the surfaces of specialised leaves (megasporophylls or ovuliferous scales)arranged into cones.Thus, gymnosperms are also known as seeded plants without flowers or phanerogams without ovary. In contrast, angiosperms are seed bearing, flowering vascular plants in which seeds are enclosed in FRUITS, and are called as phanerogams with ovary or seeded flowering plants.
