Question

If the stamens can swing freely on the filaments the condition is called
a) Basifixed
b) Dorsifixed
c) Versatile
d) Adnate

Answer 1

The androecium is the arrangement of flower organs made from stamens. Every stamen is made from a slim tail like fiber supporting a handle like a spore case or the anther. Normally the stamen comprises a two-lobed four-locule anther. The anther is discovered to be arranged on a thin fiber that bears a single vascular pack.

Complete step by step answer:
- The method of connection of the anther to the fiber changes. It is adnate when the fiber or its continuation, the connective, has all the earmarks of being joined all through the entire length of the rear of the anther as found in magnolia and water-lily.
- In mustard, Carex and different individuals from Cyperaceae, and so on., the fiber closes exactly at the base of the anther, the last being immovably fixed on the head of the previous. This condition is called basifixed or inborn.
- The attachment is dorsifixed when the fiber is immovably fixed to some situation on the rear of the a there as in energy blossom, Sesbania, and so forth.
- In many kinds of grass and in numerous lilies the connection is flexible where the fiber is joined simply at a point about the center of the connective with the goal that the anther can swing on it openly.
So the correct answer is 'Versatile'.

Additional Information: Association of stamens may include a bond (association with different individuals, viz., petals, perianth leaves, or gynoecium) or union, i.e., among the stamens themselves.
At the point when stamens follow, to petals they are named epipetalous—a condition found in numerous blossoms. At the point when the adherence is to perianth leaves, the condition is named epiphyllous as found in the cylinder rose.
Another intriguing bond is among stamens and carpels (gynandrous condition) as found in the gynostegium of Asclepia-daceae and the gynostemium of Orchidaceae.

Note: In uncommon cases, a stamen might be without fiber or sessile as found in the stamens of Arum maculatum. On the other outrageous, a stamen may not build up any prolific anther 2 when it is sterile and named a staminode as found in Cassia and Canna.
