• C. $\begin{array}{ccccc}& P& Q& R& S\\ & 2& 4& 1& 3\end{array}$
• D. $\begin{array}{ccccc}& P& Q& R& S\\ & 2& 1& 4& 3\end{array}$

Answer 1

The correct option is B $\begin{array}{ccccc}& P& Q& R& S\\ & 3& 2& 4& 1\end{array}$

Aleurone is a proteinaceous layer present on the seed.

When the fruit is formed without fertilization, it is refered to as parthenocarpic fruits.

Ovule is formed as a result of double fertilization by the male and female gametes (syngamy).

Endosperm is a food storing tissue. It provides nutrition to the germinating seeds.

$\begin{array}{cccc}& \text{Column-I}& & \text{Column-II}\\ P& \text{Aleurone layer}& -& \text{Present on seed}\\ Q& \text{Parthenocarpic fruit}& -& \text{Forms without fertilization}\\ R& \text{Ovule}& -& \text{Double fertilization}\\ S& \text{Endosperm}& -& \text{Provides nutrition}\end{array}$
