Question:
Draw a well-labeled diagram of sectional view of male gametophyte/microspore of an angiosperm and write the functions of any two parts labelled. (Any four labels).
Draw a well-labeled diagram of sectional view of male gametophyte/microspore of an angiosperm and write the functions of any two parts labelled. (Any four labels).
Show Hint
The male gametophyte plays a vital role in sexual reproduction in angiosperms by delivering sperm cells to the ovule.

\end{figure}
Diagram: Microspore with labeled parts (e.g., vegetative nucleus, generative nucleus, exine, intine).
Functions:
Vegetative nucleus: Controls pollen tube growth.
Generative nucleus: Divides to form two male gametes for fertilization.
