Question

Synandrous condition is fusion of
A. Filaments only
B. Both filaments and anthers
C. Anthers only
D. Petals

Answer 1

Hint: The synandrous condition is found in the Cucurbitaceae family. In this condition stamen fused along both their filaments and anthers.

Complete Answer:
- The flower is a specially developed shoot responsible for sexual reproduction in angiosperms. Flowers give large variation in size, shape, color and alignment of floral parts.
- In a typical flower there are four different parts such as sepals, petals, stamens and carpels.
- A flower consisting both stamens and carpels is known as bisexual and when one of them is lack the flower is referred as unisexual.
- The unisexual flower may be either staminate (or male) or pistillate (or female).

Now, let us find the solution from the option.
- Stamens are united throughout their whole length by filaments and anthers e.g. Cucurbitaceae.
- When only filaments are together to produce a single bundle, the condition is called monadelphous.
- When both the anthers and filaments are together, the condition is called as synandrous.
- When only the anthers are together, the condition is referred to as syngenesious.

Thus, the correct option is B i.e. Both filaments and anthers.

Note: It is a slightly different condition in which stamens are united throughout their whole length. Synandrous Condition also known as syngenesious. It is the opposite of monadelphous, in monoadelphous all anthers are united but their filaments remain free.
