Pick up the correct statement for androecium of the Cucurbitaceae family
(A)Indefinite stamens
(B)Syngenesious
(C)Monadelphous stamens
(D)Synandrous
Solution
The Cucurbitaceae family possess unique structures of stamens in their flowers. They are united in a specific manner which is characteristic of this family. Some important examples of such plants include squash, pumpkin, zucchini, etc.
Complete answer:
The statement of the androecium of the Cucurbitaceae family being Synandrous is correct as the flowers of this family possess stamens that are united by their filaments as well as anthers.
Indefinite stamens refer to the condition in which the flowers possess too many stamens to count, but such a condition is not seen in the case of Cucurbitaceae.
Syngenesious refers to the stamens being united by their anthers only but the filaments remain free. Such a condition is also not seen in Cucurbitaceae flowers
Monadelphous is the condition in which the stamens are united but the anthers remain free. The Cucurbitaceae family doesn't show such a condition.
Therefore, the correct answer will be "Synandrous".
Additional Information: Most of the Cucurbitaceae plants are annual vines like a gourd, zucchini, etc but some may be woody lianas, thorny shrubs, or even trees. They have large, yellow, or white flowers with hairy and pentangular stamens. Tendrils are present perpendicular to the leaf petiole at nodes whereas leaves are alternate simple palmately lobed or compound. The flowers are mainly unisexual dioecious or Monoecious. The fruits are known as pepo.
