Question

A flower having both sepals and petals is
A. Achlamydeous
B. Dichlamydeous
C. Monochlamydeous
D. Diclinous

Answer 1

Hint: In plants flower is a modified condensed shoot bearing floral leaves (sepals, petals, stamens, and carpels), which carries sexual reproduction and gives rise to fruits and seeds. These four different kinds of whorls are arranged successively on the swollen end of stalk or pedicel called the thalamus.

Complete answer:
Sepals- outermost whorl of a flower is known as sepals which are collectively called the calyx. These are green in color.
Petals- these are beautiful having different colors floral whorls surrounding reproductive organs of a flower collectively known as the corolla. These attract insects and animals.
Both sepal and petal are collectively known as Perianth.
Stamen- are male reproductive organs also called Androecium.
Carpel- is a female reproductive organ also called Gynoecium.
Flowers can be classified on the basis of sepals and petals as follows:
Option- A -Achlamydeous
When in a flower both the sepals and petals are absent is called an achlamydeous flower. Only sexual parts are present in this type of flower.
Option- B – Dichlamydeous
When in a flower both the sepals and petals are present, this type of flower is known as a dichlamydeous flower.
Option- C -Monochlamydeous
When in a flower only one accessory whorl is present which is perianth this type of flower is called a monochlamydeous flower.
Option- D -Dicilinous
When in a flower either stamens or carpels are absent this type of flower is called a dicilinous flower.

So, the correct answer to this question is option B” Dichlamydeous”

Note: There are many types of classification based on parts of the flower which can be understood by studying flowers. Sepals and petals are accessory organs while stamens and carpels are the reproductive organs of a flower.
