Protozoan sexual reproduction, SEM Z105 / 0240
Protozoan sexual reproduction. Coloured scanning electron micrograph (SEM) of two Paramecium caudatum protozoa reproducing sexually by a method called conjugation. Sexual reproduction involves mixing genetic material, as opposed to the cloning of the genetic material in asexual reproduction. These protozoa conjugate by forming a connection (not seen) through which they exchange genetic material. Paramecium protozoa can also reproduce asexually by binary fission. The filaments in the background are Oscillatoria sp. blue-green algae. P. caudatum are single-celled aquatic micro- organisms that feed on plant matter and bacteria. Magnification: x550 when printed 10cm wide

EDITORS COMMENTS
This print showcases the intricate process of protozoan sexual reproduction. In this colored scanning electron micrograph (SEM), two Paramecium caudatum protozoa are seen engaging in a method called conjugation. Unlike asexual reproduction, where genetic material is cloned, sexual reproduction involves the mixing of genetic material. The image reveals these single-celled aquatic micro-organisms forming a connection that allows them to exchange genetic material. Although this connection is not visible in the photo, its significance in facilitating reproduction cannot be underestimated. In the background, filaments of Oscillatoria sp. , blue-green algae, add an element of beauty and complexity to the composition. These organisms serve as part of the environment for P. caudatum and contribute to their sustenance by providing plant matter and bacteria for feeding. Paramecium protozoa possess cilia and an oral groove which aid in their locomotion and feeding processes respectively. This SEM offers us a rare glimpse into their reproductive behavior, shedding light on one aspect of their fascinating life cycle. With a magnification level of x550 when printed 10cm wide, this photograph captures both scientific precision and aesthetic appeal. It serves as a reminder that even at microscopic levels, nature's wonders continue to amaze us with its diversity and intricacy.
