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 ...

Plants, algae and some bacteria are able to perform photosynthesis, which is the process of transforming sunlight energy into sugar. Animals are generally unable to use this process to acquire energy, ...

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 ...

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 ...

This transmission electron micrograph shows bacteria-feeding in the green alga Cymbomonas. In the cross-section features a large vacuole (v) containing bacterial cells. It also shows the tubular duct ...

Photosynthesis takes place in specialized membrane systems, made up of stacked disks linked together by unstacked planar leaflets. A team of Ludwig-Maximilians-Universitaet (LMU) in Munich has now ...
