Question

Flower with floral organs in five circles is
A: Pentamerous
B: Pentacyclic
C: Pentacular
D: Obdiplostemonous

Answer 1

Hint: Flowers are mostly arranged in cyclical patterns. The petals, sepals, stamen and carpel form the different organs of the flowers. The term cyclic refers to the number of whorls contained within the flower. These are normally found in the cyclical arrangement. In every flower arrangement of the floral organs are different.

Complete answer:
Most of the flowers are arranged in cyclical patterns.
Identical organs are attached to the same point of axis.
These cyclical arrangements can be various types. Hemicyclic, pentacyclic, tetracyclic and tricyclic.
Hemicyclic are spirally arranged sepals on cyclic flowers.
Tetracyclic contained only one whorl of stamen.
Tricyclic are single undifferentiated perianth.
Pentacyclic refers to five whorls that are calyx, corolla, two whorls of stamen and single whorls of carpels.
Five chambers of the ovary are called pentacular.
The flower where five petals and sepals are there are called pentamerous.
Obdiplostemonous are the arrangement of two sets of stamens in alternating whorls outer whorls opposite to petals.

Hence, the correct option is option B. Pentacyclic.

Note:
Pentacyclic is a cyclical arrangement of the flower in five whorls that is calyx, corolla, two whorls of stamen and single whorls of carpels. Most of the flowers are arranged in cyclical patterns attached to the same point of the axis. There are various types of arrangement that include hemicyclic, pentacyclic, tetracyclic and tricyclic. The most common arrangement is the pentacyclic arrangement. In some cases spiral arrangement is also seen.
A flower diagram is a cross-sectional diagram of a flower that will look like if all parts of the flower are cut in the same plane. This is a basic map plan that displays the horizontal or horizontal position of the color sections. Assuming that all parts of the flower are in their original position, it represents a young bud that can be seen in a horizontal plane.
