Open in App
Solution
The correct option is A Actinomorphic, hypogynous with twisted aestivation
China
rose flower is complete (bisexual), actinomorphic, pentamerous,
hypogynous and solitary. When a flower can be divided into two equal
radial halves in any radial plane passing through the centre, it is
said to be actinomorphic. In the hypogynous flower,
the gynoecium occupies the highest position while the other parts are
situated below it. The ovary in such flowers is said to be superior, e.g.,
mustard, china rose and brinjal. When sepals or petals are arranged in a whorl and if
one margin of the appendage overlaps that of the next one and so on as in
china rose, ladyfinger and cotton, it is called twisted aestivation.
So,
the correct answer is option A.
