Pollen tubes of lily pollen, SEM
Pollen tubes of lily pollen, coloured scanning electron micrograph (SEM). Two pollen grains (brown) have sprouted pollen tubes (orange). A pollen tube is produced by a pollen grain when it lands on the pistil (female part) of a flower. The tube burrows through the pistil to the ovaries, carrying the male sex cells to them for fertilisation. Magnification: x550 when printed 10cm high

Grains Pistil Pollen Grain Pollen Tube Pollinating Re Production Reproductive Tubes False Coloured
EDITORS COMMENTS
This print showcases the intricate beauty of pollen tubes from a lily flower, captured using a scanning electron microscope (SEM). The image reveals two pollen grains in brown color, each sprouting vibrant orange pollen tubes. These delicate structures are formed when a pollen grain lands on the pistil, which is the female part of a flower. Pollen tubes play a crucial role in plant reproduction. They serve as conduits for male sex cells to reach the ovaries for fertilization. In this mesmerizing snapshot, we witness these tiny tubes burrowing through the pistil and making their way towards the ovaries. The false-colored SEM technique used here enhances our understanding of botanical processes by highlighting key features that would otherwise be invisible to the naked eye. With a magnification level of x550 when printed at 10cm high, this print allows us to appreciate nature's microscopic wonders up close. As we delve into this world of biology and botany, it becomes evident how essential pollination is for plants' survival and propagation. This stunning image not only captures an awe-inspiring moment but also reminds us of the remarkable complexity and interconnectedness found within nature's realm.
