Coloured SEM of mitochondria in ovarian cells
Mitochondria. Coloured Scanning Electron Micro- graph (SEM) of mitochondria and smooth endoplasmic reticulum in an ovarian granulosa- lutein cell. The cell occurs in the corpus luteum of the ovary, which develops after ovulation and secretes the hormone progesterone. Mitochondria (pink) are seen sectioned, containing tubular cristae. Active secretory cells have many mitochondria which play a role in cell respiration. Membranes of smooth endoplasmic reticulum (ER, yellow) are also seen; commonly found in secretory cells, ER synthesizes lipids and transports substances around the cell. Magnification: x21, 300 at 6x7cm size. Magnification: x27, 400 at 4x5 inch size

EDITORS COMMENTS
This print showcases the intricate beauty of ovarian cells, specifically highlighting mitochondria and smooth endoplasmic reticulum. The image reveals a coloured scanning electron micrograph (SEM) that provides a detailed view of these cellular structures within an ovarian granulosa-lutein cell found in the corpus luteum. Mitochondria, depicted in delicate shades of pink, are prominently displayed with their tubular cristae clearly visible. These energy-producing powerhouses are crucial for cell respiration and play a vital role in active secretory cells like this one. Meanwhile, the yellow membranes represent the smooth endoplasmic reticulum (ER), which is responsible for lipid synthesis and intracellular transportation. The corpus luteum itself forms after ovulation and serves as a site for progesterone secretion – an essential hormone involved in reproductive processes. This image offers valuable insights into the structure and function of these fascinating cells found within the ovary tissue. With magnifications ranging from x21,300 at 6x7cm size to x27,400 at 4x5 inch size, this photograph captures even the tiniest details with remarkable clarity. It serves as a testament to both the complexity of biological systems and the incredible advancements made possible through microscopy techniques. This stunning visual representation was captured by Science Photo Library's team of experts dedicated to showcasing scientific wonders while contributing to our understanding of biology on a microscopic level.
