Cucumber peel color can decide whether a fruit looks fresh, desirable, and worth buying. In many markets, especially in ...

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

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 ...

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 ...

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 ...

Optimal packing problems have inspired mathematicians for centuries. Biophysicists now add a layer to the question: How do chloroplasts arrange themselves optimally within cells, when the meaning of ...

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 ...

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 ...

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 ...

Energy production in nature is the responsibility of chloroplasts and mitochondria and is crucial for fabricating sustainable, synthetic cells in the lab. Mitochondria are not only "the powerhouses of ...

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 ...
