A certain species of sea slug steals chloroplasts from algae and houses its contraband in special organelles that it can raid ...

Marine creatures house contraband structures in special organelles, which the animal raids for food in times of need.

The macromolecular organization of photosynthetic complexes within the thylakoids of higher plant chloroplasts has been a topic of significant debate. Using in situ cryo-electron tomography, this ...

DISCUSSION. In this meta-analysis, we showed that toxic metals (Pb and Al) affect plant physiology by reducing photosynthetic activity. Although photosynthesis is important to determine plant vigor, ...

It involves the capture and conversion of sunlight into chemical energy. This process occurs in the grana of the chloroplast, or more specifically in the thylakoid membranes. Light is absorbed by the ...

Citation: Chloroplasts' ancient origins: Organelles may have emerged as energy producers before switching to carbon assimilation (2024, December 10) retrieved 27 June 2025 from https://phys.org ...

Scientists found molecular evidence supporting the idea that chloroplasts originated as energy-generating organelles and only later evolved to support carbon assimilation in plant cells.

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 ...

However, Matsunaga says that "by mixing in chloroplast-implanted cells, oxygen could be supplied to the cells through photosynthesis, by light irradiation, thereby improving the conditions inside ...
