megasporophyll of pinus bears how many ovules
Answers
Answer:
Pinus is a monoecious plant that carry both male and female cone on the same plant but on different branches. The male cone (staminate /microsporangiate strobilus) bears spirally arranged microsporophylls on the central axis. Each microsporophyll carries two microsporangia on the underside. Option C is correct.
The female cone (ovulate strobilus /megasporangiate strobilus) bears two types of scales, the bract and ovuliferous scales, which are together termed as megasporophylls. This makes option D incorrect.
Option A is incorrect as ligule is a vegetative not reproductive structure. Anther is a broad knob part of stamen that contains two long and cylindrical microsporangia in its lobes. It is found in flowering plants only.
