Options
A.tree habit
B.green leaves
C.ovules not enclosed in ovary
D.wood
Solution
Gymnosperms (eg, Pinus) are commonly clled as naked seeded plants since their ovules (which later become seed) are not covered and lie naked on the surfaces of speicalised leaves (mgasporophylls or ovuliferous scales) arranged into cones. Thus gymnosperms are also known as seeded plants without flowers or phanerogams without ovary. In contrast an giosperms are seed bearing, flowering vascular plants in which seeds are enclosed in fruits, and are called as phanerogams with ovary or seeded flowering plants.
