Question

In Pinus male and female reproductive structures occur [MP PMT 1996]
A) On different branches of the same plant
B) On different plants
C) On same branch
D) None of these

Answer 1

In Pinus male and female reproductive structures occur on different branches of the same plant (tree).   So option (A) is correct.

Usually on a pine tree the female reproductive structures (female cones) are bigger. They are found on the top branches of the tree.

The male cones are smaller and are on the lower branches. Thus the Pinus is a monoecious plant.  Because Pine tree is deciduous and sheds pollen, cones, leaves in every autumn, they are again reproduced in spring.

Answer 2

In Pinus male and female reproductive structures occur on different branches of the same plant (tree)
So the answer is
A On different branches of the same plant
