Question

The ________ are collectively called the calyx.

a. sepals

b. petals

c. tepals

d. stamens

Short answer

The Correct Answer is Option (a)

Sepals are collectively called the Calyx.

Step-by-step solution

Introduction

The flower is the reproductive part of the plant body. The four whorl components are the Calyx, Corolla, Androecium and Gynoecium.

• The calyx and corolla are non-essential components of the flower.
• Androecium and gynoecium are two essential parts of the flower.
• The androecium is the male reproductive part of the flower.
• The female reproductive part of the flower called the gynoecium.

Reason for the Incorrect options

• The petals are collectively known as the Corolla. Petals are brightly coloured to attract insects for pollination. They're designed to aid pollination and thus increase the flower's chances of reproduction.
• Tepals are formed when the calyx and corolla are fused together and are indistinguishable from one another.
• Stamens are the male reproductive part of the flower. A stamen is made up of an anther and a filament.

Reason for the correct option

Sepals are collectively called the calyx. Sepals, which are green leaf-like appendages, surround the closed bud. It protects the flower during the bud stage. It can also perform photosynthesis.

As a result, the proper response is (a).
