Which part of the pollen grain develops into the pollen tube?a)Exineb)...
The intine, which is the inner layer of the pollen grain wall, plays a crucial role in the development of the pollen tube. When a pollen grain lands on a compatible stigma, the intine extends out through the germ pore to form the pollen tube. This tube grows down the style to deliver the male gametes to the ovule for fertilisation. The intine's composition, primarily cellulose and pectin, allows it to expand and grow, facilitating this critical process in plant reproduction.
