Question

(i) Show the development of a megaspore mother cell up to the formation of a mature embryo sac in flowering plants with the help of labelled diagrams only.

Hint:

The development of the embryo sac is essential for fertilization in flowering plants.

Answer 1

\begin{figure}[H] \centering \includegraphics[width=0.7\textwidth]{Screenshot 2025-01-16 182923.png} % Replace 'path_to_image' with the actual path to your image file \caption{Development of a megaspore mother cell into a mature embryo sac.} \label{fig:embryo_sac_development} \end{figure} The development involves the differentiation of a diploid megaspore mother cell (MMC) within the ovule. It undergoes meiosis to form four haploid megaspores, of which only one survives. The surviving megaspore undergoes three mitotic divisions, forming an eight-nucleate, seven-celled embryo sac. % Quick tip
