Question

Which of the following parts of the flower are regarded as sterile and fertile?

• A. $\begin{array}{ccc}\text{Label}& \text{Sterile}& \text{Fertile}\\ \text{A}& \text{Thalamus}& -\\ \text{B}& -& \text{Corolla}\\ \text{C}& -& \text{Carpel}\\ \text{D}& \text{Calyx}& -\end{array}$
• B. $\begin{array}{ccc}\text{Label}& \text{Sterile}& \text{Fertile}\\ \text{A}& \text{Receptacle}& -\\ \text{B}& -& \text{Corolla}\\ \text{D}& \text{Calyx}& -\\ \text{E}& -& \text{Stamen}\end{array}$
• C. $\begin{array}{ccc}\text{Label}& \text{Sterile}& \text{Fertile}\\ \text{A}& \text{Pedicel}& -\\ \text{C}& -& \text{Carpel}\\ \text{D}& \text{Calyx}& -\\ \text{E}& -& \text{Stamen}\end{array}$
• D. $\begin{array}{ccc}\text{Label}& \text{Sterile}& \text{Fertile}\\ \text{A}& \text{Pedicel}& -\\ \text{B}& \text{Calyx}& -\\ \text{C}& -& \text{Carpel}\\ \text{E}& -& \text{Stamen}\end{array}$

Answer 1

The correct option is D $\begin{array}{ccc}\text{Label}& \text{Sterile}& \text{Fertile}\\ \text{A}& \text{Pedicel}& -\\ \text{B}& \text{Calyx}& -\\ \text{C}& -& \text{Carpel}\\ \text{E}& -& \text{Stamen}\end{array}$

Angiosperm flowers bear both fertile parts which have the ability to reproduce and sterile parts which do not have the ability to reproduce. They are given below:

$\begin{array}{ccc}\text{Label}& \text{Sterile}& \text{Fertile}\\ \text{A}& \text{Pedicel}& -\\ \text{B}& \text{Calyx}& -\\ \text{C}& -& \text{Carpel}\\ \text{D}& \text{Corolla}& -\\ \text{E}& -& \text{Stamen}\end{array}$
