Scientists have long known that chloroplasts help plants turn the sun’s energy into food, but a new study, led by plant biologists at the University of California, Davis, shows that they are also ...

Chloroplasts have resided in cells with a nucleus for about a billion years now. That the chloroplasts have discovered ways of communicating to the nucleus is not entirely surprising.

Plant cells have some specialized properties that make them distinct from animal cells. Learn how special structures, such as chloroplasts and cell walls, create this distinction.

Scientists agree this process occurred twice, leading to the development of mitochondria—organelles that produce energy—and ...

In contrast, chloroplasts employ an NTT protein to import ATP from the cytoplasm to fuel photosynthesis, starch synthesis, ...

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 ...

Chloroplasts even seemed to squeeze until haustoria collapsed, helping to counteract the infection. Bozkurt says he was shocked by how dynamic the chloroplasts’ reaction was.

The chloroplasts were sourced from red algae, while the animal cells were cultured from hamsters. Previous studies had found success in transplanting chloroplasts into yeast , granting them the ...

The team isolated the chloroplasts from algal cells using a centrifuge and gentle stirring. Instead of then piercing the host cells’ membranes, as in earlier work, the researchers adjusted the ...

Chloroplasts, the parts of cells that allow plants and algae to photosynthesize, are thought to have originated more than 1 billion years ago, when photosynthetic cyanobacteria lived symbiotically ...

But transplanting chloroplasts into animal cells is a bigger challenge. One of the major hurdles the researchers faced is that most algal chloroplasts become inactive below 37 degrees Celsius (98.6 ...
