Chloroplasts are generally spherical, but a small percentage of them change their shape and send out tube-like projections called "stromules." First observed over a century ago, the biological ...

Plant cells have several structures not found in other eukaryotes. In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls ...

Energy-making chloroplasts from algae have been inserted into hamster cells, enabling the cells to photosynthesize light, according to new research in Japan. It was previously thought that combining ...

"For a second I thought it was an overhead shot of a lush golf hole." ...

Scientists have identified three different signals that indicate damage to chloroplasts -- the photosynthetic factories of plant cells that give plants their green color -- but little is known about ...

Chloroplasts may seem like docile farmers of light. But inside these microscopic plant and algal cell structures lurks the spirit of a warrior. When a pathogen attacks a plant, chloroplasts stop ...

Mitochondria and chloroplasts likely evolved from engulfed prokaryotes that once lived as independent organisms. At some point, a eukaryotic cell engulfed an aerobic prokaryote, which then formed an ...

Studying sea slugs in the group Sacoglossa can mean being on the receiving end of some very imaginative emails. Sidney K. Pierce, of the University of South Florida, retired a few years ago. “But to ...

Cucumber peel color can decide whether a fruit looks fresh, desirable, and worth buying. In many markets, especially in northern China, darker green cucumbers are preferred over paler ones. That makes ...

Plants of different species can swap chloroplasts, the little cellular factories that capture energy from sunlight, when stems graft together. The surprising discovery may explain why evolutionary ...

Under cold conditions, not only the mother plant but also the father plant can pass on its chloroplasts to the offspring. Scientists at the Max Planck Institute of Molecular Plant Physiology in ...

Experimental seedlings in the laboratory. UC Davis plant biologists have discovered how chloroplasts, responsible for photosynthesis in green plants, also play a key role in plant immunity to ...
