Daffodil pollen, SEM
Daffodil pollen grains. Coloured scanning electron micrograph (SEM) of pollen grains from a daffodil flower (Narcissus pseudonarcissus). The grains have a highly sculptured outer wall (exine), which may assist in their dispersal by improving their adherence to pollinating insects. The characteristic surface of a pollen grain is used by botanists to recognise and classify plants. Each pollen grain contains a male gamete (reproductive cell) that is intended to fertilise an egg or ovule (female gamete), and initiate the formation of a seed for a new plant. Magnification: x900 when printed at 10 centimetres wide

Daffodil Dispersal Exine Gamete Gametes Grain Grains Outer Wall Pollen Reproduction Reproductive Sculpted Narcissus Pseudonarcissus
EDITORS COMMENTS
This print showcases the intricate beauty of daffodil pollen grains, captured using a scanning electron microscope (SEM). The coloured micrograph reveals the highly sculptured outer wall, known as exine, which plays a crucial role in their dispersal by enhancing adherence to pollinating insects. This unique surface texture is also utilized by botanists for plant recognition and classification. Each pollen grain depicted here contains a male gamete, or reproductive cell, responsible for fertilizing an egg or ovule – the female gamete. This vital union initiates the formation of a seed that will eventually grow into a new daffodil plant. The magnification level used for this print allows us to appreciate these minute structures at 900 times their actual size when printed at 10 centimeters wide. The image not only highlights the biological significance of pollen grains but also serves as a reminder of nature's incredible complexity and diversity. It invites us to marvel at the microscopic wonders that contribute to our planet's ecosystem and sustenance. This stunning photograph from Science Photo Library provides an awe-inspiring glimpse into the world of botany and biology while celebrating the remarkable reproductive mechanisms found within flowers like daffodils.
