The sunlight-collecting organelles known as chloroplasts solve a packing problem: how to optimize photosynthesis without ...

Life as we know it wouldn’t be possible without chloroplasts — those tiny, bean-shaped structures inside plant and algae cells that harness the sun’s energy to turn water and carbon dioxide into ...

The photosynthetic sea slug, Plakobranchus ocellatus type black, (left) and an electron micrograph displaying sequestered algal chloroplasts within a sea slug cell (right). Disclaimer: AAAS and ...

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 ...

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 ...

The impacts of the prokaryotic ancestry of chloroplasts extend to the occurrence of a bacterial ‘alarm’ hormone, or alarmone, in plants, which is triggered by nutrient deficiency or stress. A new ...
