Scots pine pollen, SEM
Scots pine pollen. Coloured scanning electron micrograph (SEM) of Scots pine (Pinus sylvestris) pollen grains. The pollen grains consist of a base (orange) with two air-filled, wing-like bladders (pink), which are extensions of the pollen grains wall. These wings help the wind-dispersed pollen to float on air. Pollen grains are the male gametes (sex cells) of a plant. Magnification: x800 when printed 10 centimetres wide

EDITORS COMMENTS
This print showcases the intricate beauty of Scots pine pollen grains. Under the scanning electron microscope (SEM), these male gametes of Pinus sylvestris reveal a stunning array of colors and structures. The base of each grain, depicted in vibrant orange, supports two delicate wing-like bladders colored in soft pink. These wings serve a crucial purpose in dispersing the pollen through wind. The SEM image also highlights the meticulous details that make up these reproductive parts. Each pollen grain possesses extensions known as exine, which form its outer wall and give it a unique shape. With a magnification level of x800 when printed at 10 centimeters wide, this photograph allows us to appreciate nature's microscopic wonders on an enlarged scale. In addition to their aesthetic appeal, these pollen grains play an essential role in plant reproduction as they carry the male sex cells necessary for fertilization. As wind-dispersed particles, they rely on their lightweight wings to float effortlessly through the air until reaching receptive female cones or flowers. Through this visually striking image captured by Science Photo Library, we gain insight into the fascinating world of botany and biology while marveling at nature's ingenious mechanisms for ensuring plant propagation.
