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 ...

Two studies published in the journal Cell shed light on the assembly, function and evolutionary diversity of the chloroplast protein import system. Chloroplasts are fundamental organelles in plant ...

Bright light triggers the chloroplast of a bioluminescent algae to fold into a pattern that minimizes the chloroplast’s exposed area. The chloroplasts of an alga called Pyrocystis lunula fold in on ...

Take a fascinating microscopic journey inside a leaf. See its tiny structures up close and discover why the chloroplasts can look like a miniature city filled with microscopic inhabitants. #Microscope ...

Plants fix 258 billion tons of CO 2 in their chloroplasts through photosynthesis every year. For these cell organelles to work properly, they require certain minerals—particularly ions of the metals ...

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 ...

SAN ANTONIO — Students at Edison High School added a salt solution to their microscope slides and watched in awe Wednesday as tiny dots of chloroplasts in plant cells moved away from the outer walls.
