Field pennycress flowers, SEM

Field pennycress flowers. Coloured SEM (scanning electron micrograph) of the developing flowers of the field pennycress (Thlaspi arvense). The flowers house the male reproductive organs (stamens), which are each topped by a pollen sac (anther, one at lower centre, brown). The flowers also contain the female reproductive organ (carpel, not seen). Pennycress is considered an agricultural weed that grows on waste ground and headlands throughout Europe, USA, eastern Asia & northern Africa. It is also known as the stinkweed due to its unpleasant smell. It may be used as a salad leaf, but can be poisonous to livestock. Magnification: x8 at 6x7cm size

EDITORS COMMENTS
This print showcases the intricate beauty of field pennycress flowers, captured through a scanning electron microscope (SEM). The vibrant colors bring to life the developing flowers of Thlaspi arvense, commonly known as field pennycress. Each flower houses the essential male reproductive organs called stamens, distinguished by their pollen sacs or anthers seen in brown at the lower center. Although not visible in this image, these flowers also contain the crucial female reproductive organ known as a carpel. Field pennycress is considered an agricultural weed that thrives on waste ground and headlands across Europe, USA, eastern Asia, and northern Africa. Its notorious nickname "stinkweed" stems from its unpleasant odor. While it may be used as a salad leaf for human consumption, caution must be exercised as it can prove poisonous to livestock. The magnification level of x8 at 6x7cm size allows us to appreciate every minute detail of these delicate floral structures. From petals to stamen filaments and stigma reproduction organs, this SEM image provides valuable insights into the anatomy and biology of field pennycress. This remarkable photograph serves as a testament to both nature's exquisite design and scientific exploration. It invites viewers into the fascinating world of botany while shedding light on an often overlooked plant species with its own unique story within our ecosystem.
