The sun is the ultimate source of energy for virtually all organisms. Photosynthetic cells are able to use solar energy to synthesize energy-rich food molecules and to produce oxygen.

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 ...

Scientists have shed new light on a relationship between a sea slug and tiny structures called chloroplasts from their food algae that allow the animals to photosynthesise in a similar way to plants.

Every plant cell is the product of a biological merger billions of years ago. Chloroplasts are key structures in plants and algae that capture sunlight, but originally they were free-living bacteria ...

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 ...

More than a decade ago, plant geneticists noticed something peculiar when they looked at grafted plants. Where two plants grew together, the cells of each plant showed signs of having picked up ...
